The foregoing statements are indeed a modification of our original assumption concerning the determination of the cost-price of commodities. We had originally assumed that the cost-price of a commodity is equal to the value of the commodities consumed in its production. Now, the price of production of a certain commodity is its cost-price for the buyer, and this price may pass into other commodities and become an element of their prices. Since the price of production may vary from the value of a commodity, it follows that the cost-price of a commodity containing this price of production may also stand above or below that portion of its total value which is formed by the value of the means of production consumed by it. It is necessary to remember this modified significance of the cost-price, and to bear in mind that there is always the possibility of an error, if we assume that the cost-price of the commodities of any particular sphere is equal to the value of the means of production consumed by it. Our present analysis does not necessitate a closer examination of this point. It remains true, nevertheless, that the cost-price of a commodity is always smaller than its value. For no matter how much the cost-price of a commodity may differ from the value of the means of production consumed by it, a previous mistake in this respect is immaterial for the capitalist. The cost-price of a certain commodity has been previously determined, it is a premise independent of the production of our capitalist, while the result of his production is a commodity containing surplus-value, which is an addition to its cost-price. For all other purposes, the statement that the cost-price is smaller than the value of a commodity is now practically changed into the statement that the cost-price is smaller than the price of production. So far as the total social capital is concerned, in the case of which the price of production is equal to the value, this statement is still identical with the former, namely that the cost-price is smaller than the value of a commodity. And while this state of things is modified in the individual spheres of production, still the fundamental fact always remains that, from the point of view of the total social capital, the cost-price of the commodities produced by it is smaller than their value, or smaller than their price of production, which in the case of the total mass of social commodities is identical with their value. The cost-price of a commodity refers only to the quantity of paid labor contained in it, while its value refers to all the paid and unpaid labor contained in it. The price of production refers to the sum of the paid labor plus a certain quantity of paid labor determined by conditions which are independent of the individual sphere in which this particular commodity was produced.

The formula that the price of production of a commodity is equal to k + p, equal to its cost-price plus profit, is now more precisely modified by the explanation that p equals kp' (p' meaning the average rate of profit), so that the price of production is equal to k + kp'. If k is 300 and p', 15%, then the price of production, being k + kp', is 300 + 300 × 15/100, or 345.

The price of production of the commodities in any particular sphere may alter its magnitude in the following cases:

In spite of the great changes occurring continually, as we shall see, in the rates of profit of the individual spheres of production, there is on the other hand no rapid change in the average rate of profit, unless it is brought about exceptionally by extraordinary economic events. A change in the average rate of profit is as a rule the belated work of a long series of fluctuations extending over very long periods of time, fluctuations which require much time before they will consolidate and compensate one another so as to bring about a change in the average rate of profit. In all short periods of time (quite aside from fluctuations of market prices), a change in the prices of production is, therefore, always traceable to actual changes in the value of commodities, that is to say, to changes in the total amount of labor-time required for their production. As a matter of course, mere changes in the money-expression of the same values are not at all considered here. 23

On the other hand it is evident that, from the point of view of the total social capital, the value of the commodities produced by it (or, expressed in money, their price) is equal to the value of the constant capital plus the value of the variable capital plus the surplus-value. Assuming the degree of labor-exploitation to be constant, the rate of profit cannot change so long as the mass of surplus-value remains the same, unless either the value of the constant capital changes, or the value of the variable capital, or the value of both, so that C is changed and thereby s/C, the general rate of profit. In every event, then, a change in the average rate of profit is conditioned on a change in the value of the commodities which form the elements of the value of the constant, or variable capital, or of both.

Or, the average rate of profit may change, if the degree of labor-exploitation changes, while the value of the commodities remains the same.

Or, if the degree of labor-exploitation remains the same, the average rate of profit may change through a relative change in the labor employed in comparison to the constant capital, as a result of technical changes in the labor-process. But such technical changes must always find expression in a change of value of the commodities, and be accompanied by it, since their production will then require either more or less labor than before.

We saw in part I that the mass of profit and surplus-value were identical. But the rate of profit was from the first distinguished from the rate of surplus-value, and this appeared to be due, at first sight, to a mere difference of calculation. But at the same time this way of looking at the question served from the outset to obscure and mystify the actual origin of surplus-value, since the rate of profit could rise or fall, while the rate of surplus-value remained the same, and vice versa, and since the capitalist had a practical interest only in the rate of profit. But there was an actual difference of magnitude only between the rates of surplus-value and of profit, not between the masses of surplus-value and of profit. Since the surplus-value was calculated on the total capital in figuring up the rate of profit, and this total capital was regarded as the standard of measurement, the surplus-value itself seemed to have its origin in the total capital and to proceed from all its parts uniformly, so that the organic difference between constant and variable capital was obliterated. In its disguise of profit, the surplus-value had actually concealed its origin, lost its character, and become unrecognizable. However, hitherto the distinction between profit and surplus-value referred only to a change of quality, or form, and there was no real difference of magnitude between the masses of surplus-value and profit, but only between the rates of surplus-value and profit, in this first stage of their metamorphosis.

But this is changed, as soon as a general rate of profit, and, by means of it, an average mass of profit corresponding to the magnitude of the capitals invested in the various spheres of production, have been established.

After that it is but accidentally that the surplus-value actually produced in any particular sphere of production, and thus the profit, is identical with the profit contained in the selling price of the commodities. It then becomes the rule, that not only the rates of surplus-value and profit are the expression of different magnitudes, but also the masses of surplus-value and of profit. Assuming a certain degree of exploitation to exist, the mass of the surplus-value produced in any particular sphere of production is now more important for the average profit of the total social capital, and thus for the capitalist class in general, than for the individual capitalist in any individual line of production. It has any importance for the individual capitalist only to the extent 24 that the quantity of surplus-value produced in his line plays a determining role in regulating the average profit. But this is a process which takes place behind his back, which he does not see, nor understand, and which indeed does not interest him at all. The actual difference of magnitude between profit and surplus-value—not merely between the rate of profit and of surplus-value—in the various spheres of production now conceals completely the true nature and origin of profit, not only for the capitalist, who has a special interest in deceiving himself on this score, but also for the laborer. By the transformation of values into prices of production, the basis of the determination of value is itself removed from direct observation. Finally, seeing that the mere transformation of surplus-value into profit separates that portion of the value of commodities which forms the profit from that portion which forms the cost-price of commodities, it is natural that the capitalist should lose the meaning of the term value at this juncture. For he is not confronted with the total labor put into the production of the commodities, but only with that portion of the total labor which he has paid in the shape of means of production, whether they be alive or dead, so that his profit appears to him as something outside of the immanent value of the commodities. And now this conception is fully endorsed, fortified, and ossified by the fact that, from the point of view of his particular sphere of production, the profit is not determined by the limits drawn for the formation of value within his own circle, but by outside influences.

The fact that the actual state of things is here revealed for the first time; that political economy up to the present time, as we shall see in the following and in volume IV, made either forced abstractions of the distinctions between surplus-value and profit, and their rates, in order to be able to retain the determination of value as a basis, or gave up the determination of value and with it all safeguards of scientific procedure, in order to cling to the obvious phenomena of these differences—this confusion of the theoretical economists demonstrates most strikingly the utter incapacity of the capitalist, when blinded by competition, to penetrate through the outward disguise into the internal essence and the inner form of the capitalist process of production.

In fact, all the laws concerning the rise and fall of the rate of profit, as analysed in part I, have the following double meaning:

1) On the one hand, they are the laws of the average rate of profit. In view of the many different causes which bring about a rise or a fall in the rate of profit, one would think that the average rate of profit would change every day. But a certain movement in one sphere will counterbalance that of another, their effects cross and paralyze one another. We shall examine later on toward which side these fluctuations gravitate ultimately. But they are slow. The suddenness, multiplicity, and different duration of the fluctuations in the individual spheres of production tend to compensate them mutually in the order of their succession in time, so that a fall in prices follows after a rise, and vice versa, limiting these fluctuations to local, individual, spheres. As a result, the various local fluctuations ultimately neutralise one another. Changes take place within each individual sphere of production, deviations from the average rate of profit, which on the one hand, balance one another after a certain time and thus do not react upon the average rate of profit, and which, on the other hand, do not react upon it, because they are balanced by other simultaneous fluctuations in other local spheres. Since the average rate of profit is determined, not only by the average profits of each sphere, but also by the allotment of the total social capital to the different individual spheres, and since this allotment is continually changing, this is another continuous cause of changes in the average rate of profit. But it is a cause of changes which largely paralyzes itself, owing to its interrupted and many sided nature.

2) Within each sphere, there is a certain playroom for a space of time in which the local rate of profit may fluctuate, before this fluctuation of rise and fall consolidates sufficiently to gain time for exerting an influence on the average rate of profit and assuming more than a local importance. Within these limits of space and time, the laws of the rate of profit, as developed in Part I of this volume, likewise remain applicable.

The theoretical conception, referring to the first transformation of surplus-value into profit, according to which every part of the capital yields uniformly the same profit, 25 expresses a practical fact. Whatever may be the composition of the industrial capital, whether it sets in motion one quarter of dead labor and three quarters of living labor, or three quarters of dead labor and one quarter of living labor, whether it absorbs three times as much surplus-labor, or produces three times as much surplus-value, in one case than in another, it yields the same profit in either case, always assuming the degree of labor-exploitation to be the same, and leaving aside individual differences, which disappear for the reason that we are dealing in either case with the average composition of the entire sphere of production. The individual capitalist, whose outlook is limited, or even all the capitalists in each individual sphere of production, justly believe that their profits are not derived solely from the labor employed in their own individual sphere. This is quite true so far as their average profit is concerned. To what extent this profit is due to the universal exploitation of labor by means of the total social capital, that is to say, by all his capitalist colleagues, this connection of things is a complete mystery for the individual capitalist. And it is all the more so, since no bourgeois economist has so far cleared it up for him. A saving of labor—not only of labor necessary for the production of a certain product, but also of the number of laborers employed—and the employment of more dead labor (constant capital), appear as very correct operations from an economic point of view, and do not seem to exert the least influence on the average rate of profit and the average profit. How, then, could living labor be the exclusive source of profit, seeing that a reduction in the quantity of labor required for production does not only seem to exert no injurious influence on profit, but even seems, under certain circumstances, to be the first cause for an increase of profits, at least for the individual capitalist?

If there is a rise or fall, in any particular sphere of production, in that portion of the cost-price which represents the value of the constant capital, it is a portion coming out of the circulation and passes from the outset into the process of production of the commodities in its enlarged or reduced state. If, on the other hand, the same number of laborers produces more or less in the same time, so that the quantity of labor required for the production of a definite quantity of commodities varies while the number of laborers remains the same, it may be that that portion of the cost-price, which represents the value of the variable capital, may remain the same and contribute the same amount to the cost-price of the total product. But every individual commodity, whose sum makes up the total product, shares in more or less labor (paid and unpaid), and shares therefore in the greater or smaller outlay for this labor, a larger or smaller portion of the wages. The total wages paid by the capitalist remain the same, but the calculation for each individual commodity is different. To that extent there would be a change in the cost-price of the commodities. But no matter whether the cost-price of the individual commodities rises or falls, either as a result of such changes of value in this same commodity, or of changes of value in its elements (or, perhaps, the cost-price of the total amount of commodities produced by a capital of a given magnitude), if the average profit is, say, 10%, it remains 10%. Still, 10%, from the point of view of the individual commodity, may represent very different amounts, according to the change of magnitude in the cost-price of the individual commodities called forth by such changes of value as we have assumed. 26

So far as the variable capital is concerned—and this is the more important, because it is the source of surplus-value, and because anything which conceals its relation to the accumulation of wealth by the capitalist serves to mystify the entire system—the matter assumes a coarser form. It appears to the capitalist in this light: A variable capital of 100 p.st. employs, perhaps, 100 laborers per week. If these 100 laborers produce 200 pieces of commodities or 200 C, per week in a given working time, then 1 C—leaving aside the question of that portion of its cost-price which is added by the constant capital, costs 10 shillings, for 100 p.st. pay for 200 c, and therefore 1 C costs 100/200 p.st. Now take it that a change takes place in the productive power of labor. Perhaps it is doubled, so that the same number of laborers now produces twice 200 C in the same time in which they used to produce once 200 C. In that case 1 C costs 5 shillings (always speaking only of that portion of the cost-price which consists of wages), for since 100 p.st. now pay for 400 C, 1 C costs 100/400 p.st. On the other hand, if the productive power were to decrease by one-half, then the same labor would produce only (200/2) C. And since 100 p.st. pay for (200/2) C, 1 C would cost 200/200 p.st., or 1 p.st. The changes in the labor-time required for the production of the commodities, and thus the changes in their values, thus appear with reference to the cost-price and the price of production as different allotments of the same wages to more or fewer commodities, according to the greater or smaller quantity of commodities produced in the same working time for the same wages. The capitalist, and consequently his political economist, see that the aliquot part of the paid labor falling to the share of each individual commodity changes with the productivity of labor, and that the value of these commodities also changes accordingly. But they do not see that the same is true of the unpaid labor contained in every individual commodity, and they see it so much less since the average profit is but accidentally determined by the unpaid labor absorbed in the sphere of the individual capitalist. Only in this vague and meaningless form are we still reminded of the fact that the value of the commodities is determined by the labor contained in them.

CHAPTER X.: COMPENSATION OF THE AVERAGE RATE OF PROFIT BY COMPETITION. MARKET PRICES AND MARKET VALUES. SURPLUS-PROFIT.

ONE portion of the spheres of production has an average composition of their capitals, that is to say, their capitals have exactly or approximately the composition of the average social capital.

In these spheres of production, the price of production of the produced commodities coincides exactly or approximately with their values as expressed in money. If there is no other way of reaching a mathematical limit, this would be the one. Competition distributes the social capital in such a way between the various spheres of production that the prices of production of each sphere are formed after the model of the prices of production in these spheres of average composition, which is k + kp', cost-price plus the average rate of profit multiplied by the cost-price. Now, this average rate of profit is nothing else but the percentage of profit in that sphere of average composition, in which the profit is identical with the surplus-value. Hence the rate of profit is the same in all spheres of production, for it is apportioned according to that one of the average spheres of production in which the average composition of capitals prevails. Consequently the sum of the profits of all spheres of production must be equal to the sum of surplus-values, and the sum of the prices of production of the total social product equal to the sum of its values. But it is evident that the balance between the spheres of production of different composition must tend to equalise them with the spheres of average composition, no matter whether this average composition is exact or only approximate. Again, there are tendencies toward equalisation between the more or less similar spheres, and these tendencies seek to bring about the ideal average, which does not really exist, so that there is a trend toward crystallisation around the ideal. In this way the tendency necessarily prevails to make of the prices of production merely changed forms of value, or to make of profits but mere portions of surplus-value, which are assigned, however, not in proportion to the surplus-value produced in each special sphere of production, but in proportion to the mass of capital employed in each sphere of production, so that equal masses of capital, whatever may be their composition, receive equal aliquot shares of the total surplus-value produced by the total social capital.

In the case of capitals of average, or approximately average, composition, the price of production coincides exactly, or approximately with the value, and the profit with the surplus-value produced by them. All the other capitals, of whatever composition, tend toward this average under the pressure of competition. But since the capitals of average composition are of the same, or approximately the same, structure as the average social capital, all capitals have the tendency, regardless of the surplus-value produced by them, to realise in the prices of their commodities the average profit, instead of their own surplus-value, in other words, to realise the prices of production.

On the other hand it may be said that whenever an average profit, and a general rate of profit, are brought about, no matter by what means, such as average profit cannot be anything else but the profit on the average social capital, the sum of these average profits being equal to the sum of surplus-values produced by the average social capitals, and that the prices brought about by adding this average profit to the cost-prices cannot be anything else but the values transformed into prices of production. It would not alter matters, if certain capitals in certain spheres of production would not submit to the process of equalisation for some reason or other. In that case the average profit would be computed on that portion of the social capital which takes part in the process of equalisation. It is evident that the average profit cannot be anything else but the total mass of surplus-values allotted to the various masses of capital in the different spheres of production in proportion to their magnitudes. The average profit is the total amount of realised unpaid labor, and this total mass of unpaid labor, the same as the paid, dead or living, labor, is materialised in the total mass of commodities and money falling to the share of the capitalists.

The real difficulty lies in the question: How is this equalisation of profits into an average rate of profit brought about, seeing that it is evidently a result, not a point of departure?

It is obvious that an estimate of the values of the commodities, for instance in money, can not be made until they have been exchanged. If we assume such an estimate, we must regard it as the outcome of an actual exchange of commodity-value for commodity-value. But how should such an exchange of commodities at their real values have come about?

Let us assume that all commodities in the different lines of production are sold at their real value. What would be the outcome? According to our foregoing analyses, the rates of profit in the various spheres of production would differ considerably. It is quite obvious that we are dealing with two different things, whether on the one hand commodities are sold at their values (that is to say, sold in proportion to the value contained in them, or exchanges with one another at the price of their values), or whether, on the other hand, they are sold at such prices that their sale yields equal amounts of profits on equal masses of the respective capitals advanced for their production.

If capitals employing unequal amounts of living labor are to produce unequal amounts of surplus-value, it must be assumed, at least to a certain degree, that the intensity of exploitation, or the rate of surplus-value, are the same, or that any existing differences in them are balanced by real or imaginary (conventional) elements of compensation. This would presuppose a competition among the laborers and an equilibration by means of their continual emigration from one sphere of production to another. Such a general rate of surplus-value—as a tendency, like all other economic laws—has been assumed by us for the sake of theoretical simplification. But in reality it is an actual premise of the capitalist mode of production, although it is more or less obstructed by practical frictions causing more or less considerable differences locally, such as the settlement laws for English farm laborers. But in theory it is the custom to assume that the laws of capitalist production evolve in their pure form. In reality, however, there is always but an approximation. Still, this approximation is so much greater to the extent that the capitalist mode of production is normally developed, and to the extent that its adulteration and amalgamation with remains of former economic conditions is outgrown.

The whole difficulty arises from the fact that commodities are not exchanged simply as commodities, but as products of capitals, which claim equal shares of the total amount of surplus-value, if they are of equal magnitude, or shares proportional to their different magnitudes. And this claim is to be satisfied by the total price realised by a certain capital on the commodities produced by it within a certain space of time. This total price, again, is but the sum of the prices of the individual commodities produced by this capital.

The essential point will become most visible, when we look upon the matter in this way: Let us assume that the laborers themselves are in possession of their respective means of production and exchange their commodities with one another. In that case these commodities would not be products of capital. The value of the various instruments of labor and raw materials would differ according to the technical nature of the labors performed in the different lines of production. Furthermore, aside from the unequal value of the means of production employed by them, they would require different quantities of means of production for given quantities of labor, according to whether a certain commodity can be finished in one hour, another in one day, and so forth. Let us assume, also, that these laborers work on an average equal lengths of time, allowing for compensations due to different intensities of labor. In that case, two laborers, both working one day, would have in the commodities produced by them, first, an equivalent for their outlay, the cost-prices of the means of production consumed by their labor. These would differ according to the technical nature of their lines of production. In the second place, both of them would have created equal amounts of new value, namely the working day added by them to the means of production. This would comprise their wages plus the surplus-value, the last representing surplus-labor exceeding their necessary wants, the product of which would belong to them. If we were to use capitalist terms, we should say that both of them receive the same wages plus the same profit, or the same value expressed, say, by the product of a working day of ten hours. But in the first place, the values of their commodities would differ. The commodities of I, for instance, might contain more value for each portion of the consumed means of production than the commodities of II. And, to introduce all possible differences, we may assume right now that the commodities of I absorb more living labor, and consequently require more labor-time for their production, than the commodities of II. Then the value of the commodities of I and II, we repeat, differs considerably. So do the sums of the values of their commodities, which represent the product of the labor performed by laborers I and II in a certain time. The rates of profit would also differ considerably for I and II, assuming that we call rate of profit, in this case, the proportion of the surplus-value to the total value of the invested means of production. The means of subsistence daily consumed by I and II during production, which take the place of wages, will form that part of the invested capital which we would call variable capital under different circumstances. But the surplus-values would be the same for I and II, or, to express it more accurately, since both I and II receive the value of the product of one day's labor, both of them receive equal values after the value of the invested "constant" capital has been deducted, and we may regard one portion of this remaining value as an equivalent for the means of subsistence consumed during production, and the other as surplus-value. If laborer I has higher expenses, they are made good by a greater portion of the value of his commodities replacing this "constant" part, and he has to reconvert a larger portion of the total value of his product into the material elements of this constant part, while laborer II, if he receives less for this purpose, has to reconvert so much less. Under these circumstances a difference in the rates of profit would be of no concern, just as it is immaterial for the wage-laborer to-day what rate of profit may express the amount of surplus-value filched from him, and just as in international commerce the difference in the various national rates of profit is immaterial for the exchange of their commodities.

The exchange of commodities at their values, or approximately at their values, requires, therefore, a much lower stage than their exchange at their prices of production, which requires a relatively high development of capitalist production.

Whatever may be the way in which the prices of the various commodities are first fixed or mutually regulated, the law of value always dominates their movements. If the labor time required for the production of these commodities is reduced, prices fall; if it is increased, prices rise, other circumstances remaining the same.

Aside from the fact that prices and their movements are dominated by the law of value, it is quite appropriate, under these circumstances, to regard the value of commodities not only theoretically, but also historically, as existing prior to the prices of production. This applies to conditions, in which the laborer owns his means of production, and this is the condition of the land-owning farmer and of the craftsman in the old world as well as the new. This agrees also with the view formerly expressed by me that the development of product into commodities arises through the exchange between different communes, not through that between the members of the same commune. 27 It applies not only to this primitive condition, but also to subsequent conditions based on slavery or serfdom, and to the guild organisation of handicrafts, so long as the means of production installed in one line of production cannot be transferred to another line except under difficulties, so that the various lines of production maintain, to a certain degree, the same mutual relations as foreign countries or communistic groups.

In order that the prices at which commodities are exchanged with one another may correspond approximately to their values, no other conditions are required but the following: 1) The exchange of the various commodities must no longer be accidental or occasional, 2) So far as the direct exchange of commodities is concerned, these commodities must be produced on both sides in sufficient quantities to meet mutual requirements, a thing easily learned by experience in trading, and therefore a natural outgrowth of continued trading, 3) So far as selling is concerned, there must be no accidental or artificial monopoly which may enable either of the contracting sides to sell commodities above their value or compel others to sell below value. An accidental monopoly is one which a buyer or seller acquires by an accidental proportion of supply to demand.

The assumption that the commodities of the various spheres of production are sold at their value implies, of course, only that their value is the center of gravity around which prices fluctuate, and around which their rise and fall tends to an equilibrium. We shall also have to note a market value, which must be distinguished from the individual value of the commodities produced by the various producers. Of this more anon. The individual value of some of these commodities will be below the market-value, that is to say, they require less labor-time for their production than is expressed in the market-value, while that of others will be above the market-value. We shall have to regard the market-value on one side as the average value of the commodities produced in a certain sphere, and on the other side as the individual value of commodities produced under the average conditions of their respective sphere of production and constituting the bulk of the products of that sphere. It is only extraordinary combinations of circumstances under which commodities produced under the least or most favorable conditions regulate the market-value, which forms the center of fluctuation for the market-prices, which are the same, however, for the same kind of commodities. If the ordinary demand is satisfied by the supply of commodities of average value, that is to say, of a value midway between the two extremes, then those commodities, whose individual value stands below the market-value, realise an extra surplus-value, or surplus-profit, while those, whose individual value stands above the market-value cannot realise a portion of the surplus-value contained in them.

It does not do any good to say that the sale of the commodities produced under the most unfavorable conditions proves that they are required for keeping up the supply. If the price in the assumed case were higher than the average market-value, the demand would be greater. At a certain price, any kind of commodities may occupy so much room on the market. This room does not remain the same in the case of a change of prices, unless a higher price is accompanied by a smaller quantity of commodities, and a lower prices by a larger quantity of commodities. But if the demand is so strong that it does not let up when the price is regulated by the value of commodities produced under the most unfavorable conditions, then these commodities determine the market-value. This is not possible unless the demand exceeds the ordinary, or the supply falls below it. Finally, if the mass of the produced commodities exceeds the quantity which is ordinarily disposed of at average market-values, then the commodities produced under the most favorable conditions regulate the market value. These commodities may be sold exactly or approximately at their individual values, and in that case it may happen that the commodities produced under the least favorable conditions do not realise even their cost prices, while those produced under average conditions realise only a portion of the surplus-value contained in them. The statements referring to market-value apply also to the price of production, if it takes the place of market-value. The price of production is regulated in each sphere, and this regulation depends on special circumstances. And this price of production is in its turn the center of gravity around which the daily market-prices fluctuate and tend to balance one another within definite periods. (See Ricardo on the determination of the price of production by those who produce under the least favorable conditions.)

No matter what may be the way in which prices are regulated, the result always is the following:

1) The law of value dominates the movements of prices, since a reduction or increase of the labor-time required for production causes the prices of production to fall or to rise. It is in this sense that Ricardo (who doubtless realised that his prices of production differed from the value of commodities) says that "the inquiry to which he wishes to draw the reader's attention relates to the effect of the variations in the relative value of commodities, and not in their absolute value."

2) The average profit which determines the prices of production must always be approximately equal to that quantity of surplus-value, which falls to the share of a certain individual capital in its capacity as an aliquot part of the total social capital. Take it that the average rate of profit, and therefore the average profit, are expressed by an amount of money of a higher value than the money-value of the actual average surplus-value. So far as the capitalists are concerned in that case, it is immaterial whether they charge one another a profit of 10 or of 15%. The one of these percentages does not cover any more actual commodity-value than the other, since the overcharge in money is mutual. But so far as the laborer is concerned (the assumption being that he receives the normal wages, so that the raising of the average profit does not imply an actual deduction from his wages, in other words, does not express something entirely different from the normal surplus-value of the capitalist), the rise in the price of commodities due to a raising of the average profit must be accompanied by a corresponding rise of the money-expression for the variable capital. As a matter of fact, such a general nominal raising of the rate of profit and the average profit above the limit provided by the proportion of the actual surplus-value to the total invested capital is not possible without carrying in its wake an increase of wages, and also an increase in the prices of the commodities which constitute the constant capital. The same is true of the opposite case, that of a reduction of the rate of profit in this way. Now, since the total value of the commodities regulates the total surplus-value, and this the level of the average profit and the average rate of profit—always understanding this as a general law, as a principle regulating the fluctuations—it follows that the law of value regulates the prices of production.

Competition first brings about, in a certain individual sphere, the establishment of an equal market-value and market-price by averaging the various individual values of the commodities. The competition of the capitals in the different spheres then results in the price of production which equalises the rates of profit between the different spheres. This last process requires a higher development of capitalist production than the previous process.

In order that commodities of the same sphere of production, the same kind, and approximately the same quality, may be sold at their value, the following two requirements must be fulfilled:

1) The different individual values must have been averaged into one social value, the above-named market-value, and this implies a competition between the producers of the same kind of commodities, and also the existence of a common market, on which they offer their articles for sale. In order that the market-price of identical commodities, which however are produced under different individual circumstances, may correspond to the market-value, may not differ from it by exceeding it or falling below it, it is necessary that the different sellers should exert sufficient pressure upon one another to bring that quantity of commodities on the market which social requirements demand, in other words, that quantity of commodities whose market-value society can pay. If the quantity of products exceeds this demand, then the commodities must be sold below their market-value; vice versa, if the quantity of products is not large enough to meet this demand, or, what amounts to the same, if the pressure of competition among the sellers is not strong enough to bring this quantity of products to market, then the commodities are sold above their market-value. If the market-value is changed, then there will also be a change in the conditions under which the total quantity of commodities can be sold. If the market-value falls, then the average social demand increases (always referring to the solvent demand) and can absorb a larger quantity of commodities within certain limits. If the market-value rises, then the solvent social demand for commodities is reduced and smaller quantities of them are absorbed. Hence if supply and demand regulate the market-price, or rather the deviations of market-prices from market-values, it is true, on the other hand, that the market-value regulates the proportions of supply and demand, or the center around which supply and demand cause the market-prices to fluctuate.

If we look closer at the matter, we find that the conditions determining the value of some individual commodity become effective, in this instance, as conditions determining the value of the total quantities of a certain kind. For, generally speaking, capitalist production is from the outset a mass-production. And even other, less developed, modes of production carry small quantities of products, the result of the work of many small producers, to market as co-operative products, at least in the main lines of production, concentrating and accumulating them for sale in the hands of relatively few merchants. Such commodities are regarded as co-operative products of an entire line of production, or of a greater or smaller part of this line.

We remark by the way that the "social demand," in other words, that which regulates the principle of demand, is essentially conditioned on the mutual relations of the different economic classes and their relative economic positions, that is to say, first, on the proportion of the total surplus-value to the wages, and secondly, on the proportion of the various parts into which surplus-value is divided (profit, interest, ground-rent, taxes, etc.). And this shows once more that absolutely nothing can be explained by the relation of supply and demand, unless the basis has first been ascertained, on which this relation rests.

Although both commodity and money represent units of exchange-value and use-value, we have already seen in volume I, chapter I, 3, that in buying and selling both of these functions are polarised at the two extremes, the commodity (seller) representing the use-value, and the money (buyer) the exchange-value. It was one of the first conditions for the sale of a commodity that it should have a use-value and satisfy some social need. The other essential condition was that the quantity of labor contained in a certain commodity should represent socially necessary labor, so that its individual value (and what amounts to the same under the present assumption, its selling price) should coincide with its social value. 28

Now let us apply this to the mass of commodities on the market, which represent the product of a whole sphere of production. The matter will be most easily explained by regarding this whole mass of commodities, coming from one line of production, as one single commodity, and the sum of the prices of the many identical commodities as one price. In that case the statements made in regard to one individual commodity apply literally to the mass of commodities sent to the market by one entire line of production. The postulate that the individual value of a commodity should correspond to its social value has then the significance that the total quantity of commodities contains the quantity of social labor necessary for its production, and that the value of this mass is equal to its market-value.

Now let us assume that the bulk of these commodities has been produced under approximately the same normal conditions of social labor, so that this social value is at the same time identical with the individual value of the individual commodities constituting this mass. In that case, a relatively small portion of these commodities may have been produced below, and another above, these conditions, so that the individual value of the one portion is greater, and that of the other smaller, than the average value of the bulk of the commodities, but in such proportions that these extremes balance one another. The average value of the commodities in these extremes is then equal to the average value of the great bulk of average commodities. Under such circumstances, the market-value is determined by the value of the commodities produced under average conditions. 29 The value of the entire mass of commodities is equal to the actual sum of the values of all individual commodities combined, no matter whether they were produced under average conditions, or under conditions above or below the average. In this case, the market-value, or the social value, of the mass of commodities—the necessary labor time contained in them—is determined by the value of the average bulk.

Let us assume, on the other hand, that the total mass of commodities brought to market remains the same, while the value of the commodities produced under the least favorable conditions is not balanced by the value of the commodities produced under the most favorable conditions, so that the mass of commodities produced under the least favorable conditions constitutes a relatively large quantity, compared to the average mass as well as to the other extreme. In that case the mass produced under the least favorable conditions determines the market-value, or social value.

Take it, finally, that the mass of commodities produced under the most favorable conditions is considerable in excess of the mass produced under the least favorable conditions, and is large even compared with the average mass. Then the mass produced under the most favorable conditions determines the market-value. We leave aside the question of a transfer of the market, whenever the mass of commodities produced under the most favorable conditions regulates the market-price. We are not dealing here with the market-price in so far as it differs from the market-value, but with the various modes of determining the market-value itself. 30

In fact, assuming the strictest case (which, or course, is realised only approximately and with a thousand modifications) of our first illustration, the market-value regulated by the average values of the total mass of commodities is equal to the sum of their individual values, although this market-value is forced as an average value upon the commodities produced at the extremes. Those who produce under the worst conditions must then sell their commodities below their individual values; those producing under the best conditions sell them above their individual values.

In the second case, the two lots of commodities produced as the two extremes do not balance one another. The lot produced under the worst conditions decides the question. Strictly speaking, the average price, or the market-value, of every individual commodity, or of every aliquot part of the total mass, would now be determined by the total value of the mass as ascertained by the addition of the values of the commodities produced under different conditions, and by the aliquot part of this total value falling to the share of the individual commodity. The market-value thus ascertained would be above the individual value, not only of the commodities belonging to the most favorable extreme, but also of those belonging to the average lot. But still it would be below the individual value of the commodities produced at the most unfavorable extreme. The extent to which this market-value would approach the individual value of this extreme, or coincide with it, would depend entirely on the volume occupied in that sphere of commodities by the lot of commodities produced at the unfavorable extreme. If the demand exceeds the supply but slightly, then the individual value of the unfavorably produced commodities regulates the market-price.

Finally, if the lot of commodities produced at the most favorable extreme occupies the greatest space, as it does in the third case, compared not only to the other extreme, but also to the average lot, then the market-value falls below the average value. The average value, computed by the addition of the sum of values of the two extremes and of the middle, stands here below that of the middle, and approaches it or recedes from it, according to the relative space occupied by the favorable extreme. If the demand is weak compared to the supply, then the favorably situated part, whatever may be its size, makes room for itself forcibly by contracting its price down to its individual value. The market-value cannot coincide with this individual value of the commodities produced under the most favorable conditions, except when the supply far exceeds the demand.

This mode of determining market-values, which we have here outlined abstractly, is promoted on the real market by competition among the buyers, provided that the demand is just large enough to absorb the quantity of commodities at the values fixed in this manner. And this brings us to the second point.

2) To say that a commodity has a use-value is merely to say that it satisfies some social want. So long as we were dealing simply with individual commodities, we could assume that the demand for any one commodity—its price implying its quantity—existed without inquiring into the extent to which this demand required satisfaction. But this question of the extent of a certain demand becomes essential, whenever the product of some entire line of production is placed on one side, and the social demand for it on the other. In that case it becomes necessary to consider the amount, the quantity, of this social demand.

In the foregoing statements referring to market-value, the assumption was that the mass of the produced commodities remains the same given quantity, and that a change takes place only in the proportions of the elements constituting this mass and produced under different conditions, so that the market-value of the same mass of commodities is differently regulated. Let us suppose that this mass is of a quantity equal to the ordinary supply, leaving aside the possibility that a portion of the produced commodities may be temporarily withdrawn from the market. Now, if the demand for this mass also remains the same, then this commodity will be sold at its market-value; no matter which one of the three aforementioned cases may regulate this market-value. This mass of commodities does not only satisfy a demand, but satisfies it to its full social extent. On the other hand, if the quantity is smaller than the demand for it, then the market-prices differ from the market-values. And the first differentiation is that the market-value is always regulated by the commodity produced under the least favorable circumstances, if the supply is too small, and by the commodity produced under the most favorable conditions, if the supply is too large. In other words, one of the extremes determines the market-value, in spite of the fact that the proportion of the masses produced under different conditions ought to bring about a different result. If the difference between demand and supply of the product is very considerable, then the market-price will likewise differ considerably from the market-value in either direction. Now, the difference between the quantity of the produced commodities and the quantity of commodities which fixes their sale at their market-value may be due to two reasons. Either the quantity itself varies, by decreasing or increasing, so that there would be a reproduction on a different scale than the one which regulated a certain market-value. If so, then the supply changes while the demand remains unchanged, and we have a relative overproduction or underproduction. Or, the reproduction, and the supply, remain the same, while the demand is reduced or increased, which may take place for several reasons. If so, then the absolute magnitude of the supply is unchanged, while its relative magnitude, compared to the demand, has changed. The effect is the same as in the first case, only it acts in the opposite direction. Finally, if changes take place on both sides, either in opposite directions, or, if in the same direction, not to the same extent, in other words, if changes take place on both sides which alter the former proportion between these sides, then the final result must always lead to one of the two above mentioned cases.

The real difficulty in determining the meaning of the concepts supply and demand is that they seem to amount to a tautology. Consider first the supply, either the product on the market, or the product which can be supplied to the market. In order to avoid useless details, we shall consider only the mass annually reproduced in every given line of production and leave out of the question the varying faculty of some commodities to withdraw from the market and go into storage for consumption at a later time, for instance next year. This annual reproduction is expressed in a certain quantity, in weight or numbers, according to whether this mass of commodities is measured continuously or discontinuously. They represent not only use-value satisfying human wants, but these use-values are on the market in definite quantities. In the second place, this quantity of commodities has a definite market-value, which may be expressed by a multiple of the market-value of the individual commodity, or of the measure, which serve as units. There is, then, no necessary connection between the quantitative volume of the commodities on the market and their market-value, since many commodities have, for instance, a high specific value, others a low specific value, so that a given sum of values may be represented by a very large quantity of some, and a very small quantity of other commodities. There is only this connection between the quantity of articles on the market and the market-value of these articles: Given a certain basis for the productivity of labor in every particular sphere of production, the production of a certain quantity of articles requires a definite quantity of social labor time; but this proportion differs in different spheres of production and stands in no internal relation to the usefulness of these articles or the particular nature of their use-values. Assuming all other circumstances to be equal, and a certain quantity a of some commodity to cost b labor time, a quantity na of the same commodity will cost nb labor-time. Furthermore, if society wants to satisfy some demand and have articles produced for this purpose, it must pay for them. Since the production of commodities is accompanied by a division of labor, society buys these articles by devoting to their production a portion of its available labor-time. Society buys them by spending a definite quantity of the labor-time over which it disposes. That part of society, to which the division of labor assigns the task of employing its labor in the production of the desired article, must be given an equivalent for it by other social labor incorporated in articles which it wants. There is, however, no necessary, but only an accidental, connection between the volume of society's demand for a certain article and the volume represented by the production of this article in the total production, or the quantity of social labor spent on this article, the aliquot part of the total labor-power spent by society in the production of this article. True, every individual article, or every definite quantity of any kind of commodities, contains, perhaps, only the social labor required for its production, and from this point of view the market-value of this entire mass of commodities of a certain kind represents only necessary labor. Nevertheless, if this commodity has been produced in excess of the temporary demand of society for it, so much of the social labor has been wasted, and in that case this mass of commodities represents a much smaller quantity of labor on the market than is actually incorporated in it. (Only when production will be under the conscious and prearranged control of society, will society establish a direct relation between the quantity of social labor time employed in the production of definite articles and the quantity of the demand of society for them.) The commodities must then be sold below their market-value, and a portion of them may even become unsaleable. The opposite takes place, if the quantity of social labor employed in the production of a certain kind of commodities is too small to meet the social demand for them. But if the quantity of social labor spent in the production of a certain article corresponds to the social demand for it, so that the quantity produced is that which is the ordinary on that scale of production and for that same demand, then the article is sold at its market-value. The exchange, or sale, of commodities at their value is the rational way, the natural law of their equilibrium. It must be the point of departure for the explanation of deviations from it, not vice versa the deviations the basis on which this law is explained.

Now let us look at the other side, the demand.

Commodities are bought either as means of production or means of subsistence, in order to be used for productive or individual consumption. It does not alter matters that some commodities may serve both ends. There is, then, a demand for them on the part of the producers (who are capitalists in this case, since we have assumed that the means of production have been transformed into capital) and on the part of the consumers. It appears at first sight as though these two sides ought to have a corresponding quantity of social demands offset by a corresponding quantity of social supplies in the various lines of production. If the cotton industry is to accomplish its annual reproduction on a given scale, it must produce the usual quantity of cotton and an additional quantity determined by the annual extension of reproduction through the necessities of accumulating capital, always assuming other circumstances to remain the same. This is also true of means of subsistence. The working class must find at least the same quantity of necessities on hand, if it is to continue living in the accustomed way, although these necessities may be of different kinds and differently distributed. And there must be an additional quantity to allow for the annual increase of population. This applies with more or less modification to the other classes.

It would seem, then, that there is on the side of demand a definite magnitude of social wants which require for their satisfaction a definite quantity of certain articles on the market. But the quantity demanded by these wants is very elastic and changing. Its fixedness is but apparent. If the means of subsistence were cheaper, or money-wages higher, the laborers would buy more of them, and a greater "social demand" would be manifested for this kind of commodities, leaving aside the question of paupers, whose "demand" is even below the narrowest limits of their physical wants. On the other hand, if cotton were cheaper, the demand of the capitalists for it would increase, more additional capital would be thrown into the cotton industry, etc. It must never be forgotten that the demand for productive consumption is a demand of capitalists, under our assumption, and that its essential purpose is the production of surplus-value, so that commodities are produced only to this end. Still this does not argue against the fact that the capitalist as a buyer, for instance of cotton, represents the demand for this cotton. Moreover it is immaterial to the seller of cotton, whether the buyer converts it into shirting or into guncotton, or whether he intends to make it into wads for his and the world's ears. But it does exert a considerable influence on the way in which the capitalist acts as a buyer. His demand for cotton is essentially modified by the fact that he disguises thereby his real demand, that of making profits. The limits within which the need for commodities on the market, the demand, differs quantitatively from the actual social need, varies naturally considerably for different commodities; in other words, the difference between the demanded quantity of commodities and that quantity which would be demanded, if the money-prices of the commodities, or other conditions concerning the money or living of the buyers, were different.

Nothing is easier than to realise the inequalities of demand and supply, and the resulting deviation of market-prices from market-values. The real difficulty consists in determining what is meant by balancing supply and demand.

Demand and supply balance one another, when their mutual proportions are such that the mass of commodities of a definite line of production can be sold at their market-value, neither above nor below it. That is the first thing we hear.

The second is this: If the commodities are sold at their market-values, then supply and demand balance.

If demand and supply balance, then they cease to have any effect, and for this very reason commodities are sold at their market-values. If two forces exert themselves equally in opposite directions, they balance one another, they have no influence at all on the outside, and any phenomena taking place at the same time must be explained by other causes than the influence of these forces. If demand and supply balance one another, they cease to explain anything, they do not affect market-values, and therefore leave us even more in the dark than before concerning the reasons for the expression of the market-value in just a certain sum of money and no other. It is evident that the essential fundamental laws of production cannot be explained by the interaction of supply and demand (quite aside from a deeper analysis of these two motive forces of social production, which would be out of place here). For these laws cannot be observed in their pure state, until the effects of supply and demand are suspended, are balanced. As a matter of fact supply and demand never balance, or, if they do, it is by mere accident, it is scientifically rated at zero, it is considered as not happening. But political economy assumes that supply and demand balance one another. Why? For no other reason, primarily, than to be able to study phenomena in their fundamental relations, in that elementary form which corresponds to their conception, that is to say, to study them unhampered by the disturbing interference of supply and demand. The other reason is to find the actual tendencies of economic movements and to fix them, as it were. For the inequalities are of an antagonistic nature, and since they continually follow one after another, they balance one another by their opposite movements, by their opposition. Since supply and demand never balance each other in any given case, their differences follow one another in such a way that supply and demand are always balanced only when looking at them from the point of view of a greater or smaller period of time. For the result of a deviation in one direction is a deviation in the opposite direction. Such a balance is only an average of past movements, a result of a continual movement in contradictions. By this means the market-prices differing from the market-values reduce one another to the average of market-values and balance the different plus and minus in their divergencies. And this average figure has not merely a theoretical, but also a practical, value for capital, since its investment is calculated on the fluctuations and compensations of more or less fixed periods of time.

The relation of demand and supply explains, therefore, on the one hand only the deviations of market-prices from market-values, and on the other the tendency to balance these deviations, in other words, to suspend the effect of the relation of demand and supply. (Such exceptions as commodities having prices without having any value are not considered here.) Demand and supply may bring about a balance in the effect caused by their inequalities in many different ways. For instance, if the demand, and consequently the market-price, fall, capital may be withdrawn and the supply reduced. But instead it may happen that the market-value itself is reduced and balanced with the market-price through inventions, which reduce the necessary labor time. Vice versa, if the demand increases, and consequently the market-price rises above the market-value, too much capital may flow into this line of production and production may be increased to such an extent, that the market-price finally falls below the market-value. Or, it may lead to a rise of prices which cuts down the demand. It may also bring about a rise in the market-value itself for a shorter or longer time, in some lines of production, in which a portion of the desired products must be produced under more unfavorable conditions during this period.

If demand and supply determine the market-price, so does the market-price, and in the further analysis the market-value determine demand and supply. This is obvious in the case of demand, which moves in opposition to price, rising when prices fall, and falling when prices rise. But it may also be noted in the case of supply. For the prices of the means of production which are incorporated in the supplied commodities determine the demand for these means of production, and thus the supply of the commodities whose supply implies the demand for these means of production. The prices of cotton are determining elements for the supply of cotton goods.

This confusion of a determination of prices by demand and supply, and at the same time a determination of supply and demand by prices, is worse confounded by the determination of the supply by the demand, and the demand by supply, of the market by production, and of production by the market. 31

Even the ordinary economist (see our foot-note) recognizes that the proportion between supply and demand may vary in consequence of a change in the market-value of commodities, without a change in the demand of supply by external circumstances. The author of the Observations continues after the passage quoted in the foot-note: "This proportion" (between demand and supply) "however, if we still mean by 'demand' and 'natural price' what we meant just now, when referring to Adam Smith, must always be a proportion of equality; for it is only when the supply is equal to the effectual demand, that is, to that demand, which will pay neither more nor less than the natural price, that the natural price is in fact paid; consequently there may be two very different natural prices, at different times, for the same commodity, and yet the proportion which the supply bears to the demand, be in both cases the same, namely the proportion of equality." It is admitted, then, that with two different natural prices of the same commodity at different times demand and supply may balance one another and must balance one another, if the commodity is to be sold at its natural price in both instances. Since there is no difference in the proportion of supply and demand in either case, but only a difference in the magnitude of the natural price itself, it follows that this price is determined independently of demand and supply, and cannot very well be determined by them.

In order that a commodity may be sold at its market-value, that is to say, in proportion to the necessary social labor contained in it, the total quantity of social labor devoted to the total mass of this kind of commodities must correspond to the quantity of the social demand for them, meaning the solvent social demand. Competition, the fluctuations of market-prices which correspond to the fluctuations of demand and supply, tend continually to reduce the total quantity of labor devoted to each kind of commodities to this scale.

The proportion of supply and demand repeats, in the first place, the relation of the use-value and exchange-value of commodities, of commodity and money, of buyer and seller; in the second place, the relation of producer and consumer, although both of them may be represented by third merchants. In studying buyers and sellers, it is sufficient to confront them individually, in order to set forth their relations. Three individuals suffice for the complete metamorphosis of commodities, and therefore for the complete transactions of sale and purchase. A converts his commodity into the money of B, to whom he sells his commodity, and he reconverts his money into commodities which he buys for it from C. The whole transaction takes place between these three. Furthermore: In the study of money it had been assumed that the commodities are sold at their values, because there was no reason to take into consideration any divergence of prices from values, it being a question of changes of form experienced by the commodities in their transformation into money and their reconversion from money into commodities. As soon as a commodity has been sold and a new commodity bought with the receipts, we have the entire metamorphosis before us, and for the consideration of this process it is immaterial whether the price of the commodity stands above or below its value. The value of the commodity is essential as a basis, because the concept of money cannot be developed on any other foundation but this one, and because price, in its general meaning, is but value in the form of money. Of course, it is assumed in the study of money as a medium of circulation that more than one metamorphosis of a certain commodity takes place. It is the social interrelation of these metamorphoses which is studied. Only by this means do we arrive at the circulation of money and at the development of its function as a medium of circulation. While this connection of the matter is very important for the transition of money into its function of a circulating medium, and for its resulting change of form, it is of no moment for the transaction between the individual buyer and seller.

In a question of supply and demand, however, the supply means the sum of the sellers, or producers, of a certain kind of commodities, and the demand the sum of the buyers, or consumers, of the same kind of commodities (both productive and individual consumers). There two bodies react on one another as units, as aggregate forces. The individual counts here only as a part of a social power, as an atom of some mass, and it is in this form that competition enforces the social character of production and consumption.

That side of competition, which is momentarily the weaker, is also that in which the individual acts independently of the mass of his competitors and often works against them, whereby the dependence of one upon the other is impressed upon them, while the stronger side always acts more or less unitedly against its antagonist. If the demand for this particular kind of commodities is larger than the supply, then one buyer outbids another, within certain limits, and thereby raises the price of the commodity for all of them above the market-price, while on the other hand the sellers unite in trying to sell at a high price. If, vice versa, the supply exceeds the demand, some one begins to dispose of his goods at a cheaper rate and the others must follow, while the buyers unite in their efforts to depress the market-price as much as possible below the market-value. The common interest is appreciated only so long as each gains more by it than without it. And common action ceases, as soon as this or that side becomes the weaker, when each one tries to get out of it by his own devices with as little loss as possible. Again, if some one produces more cheaply and can sell more goods, thus assuming more room on the market by selling below the current market-price, or market-value, he does it, and thereby he begins an action which gradually compels the others to introduce the cheaper mode of production and which reduces the socially necessary labor to a new, and lower, level. If one side has the advantage, every one belonging to it gains. It is as though they had exerted their common monopoly. If one side is the weaker, then every one may try on his own hook to be the stronger (for instance, any one working with lower costs of production), or at least to get off as easily as possible, and in that case he does not care in the least for his neighbor, although his actions affect not only himself, but also all his fellow strugglers. 32

Demand and supply imply the transformation of values into market-prices, and to the extent that they proceed on a capitalist basis, to the extent that the commodities are products of capital, they are based on capitalist processes, that is, on quite different and more complicated conditions than the mere purchase and sale of goods. In these capitalist processes it is not a question of the formal conversion of the value of commodities, into prices, not a question of a mere change of form. It is a matter of definite differences in quantity between market-prices and market-values, and, further, prices of production. In simple purchases and sales, it is enough to consider merely the producers of articles as such. But supply and demand, in a wider analysis, imply the existence of different classes and sections of classes which divide the total revenue of society among themselves and consume it as revenue among themselves, which, therefore, constitute the demand in the form of revenue. On the other hand, the attempt to grasp the question of the supply and demand among the producers as such requires an analysis of the total conformation of the capitalist process of production.

Under capitalist production it is not a question of merely throwing a certain mass of values into circulation and exchanging that mass for equal values in some other form, whether of money or other commodities, but it is also a question of advancing capital in production and realising on it as much surplus-value, or profit, in proportion to its magnitude, as any other capital of the same or of other magnitudes in whatever line of production. It is a question, then, of selling the commodities at least at prices which will yield the average profit, in other words, at prices of production. Capital comes in this form to a realisation of the social nature of its power, in which every capitalist participates in proportion to his share in the total social capital.

In the first place, capitalist production is essentially indifferent to the particular use-value, or the peculiarity, of any commodity produced by it. In every sphere of production it is the sole purpose of production to secure surplus-value, to appropriate in the product of labor a certain quantity of unpaid labor. And it is likewise the nature of the wage-labor subject to capital to be indifferent to the specific character of its labor, to transform itself in accord with the requirements of capital, and to submit to being transferred from one sphere of production to another.

In the second place, one sphere of production is now as good or as bad as another. Every one of them yields the same profit, and every one of them would be useless, if the commodities produced by them did not satisfy some social need.

Now, if the commodities are sold at their values, then, as we have shown, considerably different rates of profit arise in the various spheres of production, according to the different organic composition of the masses of capital invested in them. But capital withdraws from spheres with low rates of profit and invades others which yield a higher rate. By means of this incessant emigration and immigration, in one word, by its distribution among the various spheres in accord with a rise of the rate of profit here, and its fall there, it brings about such a proportion of supply to demand that the average profit in the various spheres of production becomes the same, so that values are converted into prices of production. This equilibration is accomplished by capital in a more or less perfect degree to the extent that capitalist development is advanced in a certain nation, in other words, to the extent that conditions in the respective countries are adapted to the capitalist mode of production. As capitalist development proceeds, it develops also its own peculiar conditions and subjects to its specific character and its immanent laws all the social requirements on which the process of production is based.

The incessant equilibration of the continual differences is accomplished so much quicker, 1), the more movable capital is, the easier it can be shifted from one sphere and one place to another; 2) the quicker labor-power can be transferred from one sphere to another and from one local point of production to another. The first condition implies complete freedom of trade in the interior of society and the removal of all monopolies with the exception of those which naturally arise out of the capitalist mode of production. It implies, furthermore, the development of the credit-system, which concentrates the inorganic mass of the disposable social capital instead of leaving it in the hands of individual capitalists. Finally it implies a subordination of the various spheres of production to the control of capitalists. This last implication is of itself included in the assumption that it is a question of a transformation of values into prices of production in all capitalistically exploited spheres of production. But this equilibration meets great obstacles, whenever numerous and large spheres of production, which are not operated on a capitalistic basis (such as farming by small farmers), are interpolated between the capitalist spheres and interrelated with them. A great density of population is also a requirement.—The second condition implies the abolition of all laws which prevent the laborers from moving from one sphere of production to another and from one local center of production to another; an indifference of the laborer to the nature of his labor; the greatest possible reduction of labor in all spheres of production to simple labor; the elimination of all craft prejudices among laborers; and last, not least, a subjugation of the laborer under the capitalist mode of production. More detailed statements concerning these points belong in a special analysis of competition.

It follows from the foregoing that the individual capitalist as well as the capitalists as a whole in each particular sphere of production are participants in the exploitation of the total working class by the total capital, and in the degree of that exploitation, not only out of general class sympathy, but also for direct economic reasons, because, assuming all other conditions, among them the value of the advanced constant capital, to be given, the average rate of profit depends on the intensity of exploitation of the total labor by the total capital.

The average profit coincides with the average surplus-value produced for each 100 of capital, and so far as the surplus-value is concerned, the foregoing statements apply as a matter of course. In the determination of the rate of profit, the value of the advanced capital becomes an additional element. In fact, the direct interest taken by the capitalist, or the capital, of any individual sphere of production in the exploitation of the laborers directly employed by him, or it, is limited to the endeavor to make an extra gain, a profit exceeding the average, either by exceptional overwork, or by a reduction of wages below the average, or by an exceptional productivity of labor. Aside from this, a capitalist who would not employ any variable capital, and therefore no laborers (an exaggerated assumption), would be as much interested in the exploitation of the working class by capital, and would derive his profit quite as much from unpaid surplus-labor, as a capitalist who would employ only variable capital (another exaggeration), and who would invest his entire capital in wages. The degree of exploitation of labor depends on the average intensity of labor, if the working day is given, and on the length of the working day, if the average intensity of exploitation is given. The degree of exploitation of labor determines the size of the rate of surplus-value, and therefore the size of the mass of surplus-value for a given total mass of variable capital, and consequently the magnitude of the profit. The individual capitalist, as distinguished from his sphere, has the same special interest in the exploitation of the laborers personally employed by him that the capital of a certain sphere, as distinguished from the total social capital, has in the exploitation of the laborers directly employed by it.

On the other hand, every particular sphere of capital, and every individual capitalist, has the same interest in the productivity of the social labor employed by the total capital. For two things depend on this productivity: In the first place, the mass of use-values by which the average profit is expressed; and this is doubly important, where this average profit serves as a fund for the accumulation of new capital and as a fund for revenue to be spent in enjoyment. In the second place, the amount of the value of the total capital invested (constant and variable), which, with a given amount of surplus-value, or profit, for the whole capitalist class, determines the rate of profit, or the profit on a certain percentage of capital. The special productivity of labor in any particular sphere, or in any individual business of this sphere, interests only those capitalists who are directly engaged in it, since it enables that particular sphere, or that individual capitalist, to make an extra profit over that of the total capital.

Here, then, we have the mathematically exact demonstration, how it is that the capitalists form a veritable freemason society arrayed against the whole working class, however much they may treat each other as false brothers in the competition among themselves.

The price of production includes the average profit. We call it price of production. It is, as a matter of fact, the same thing which Adam Smith calls natural price, Ricardo price of production, or cost of production, and the physiocrats prix nécessaire, because it is in the long run a prerequisite of supply, of the reproduction of commodities in every individual sphere. 33 But none of them has revealed the difference between price of production and value. We can well understand, then, why these same economists, who always resist a determination of the value of commodities by labor-time, by the quantity of labor contained in them, always speak of prices of production as centers, around which market-prices fluctuate. They can afford to do that, because the price of production is an utterly external and, at first glance, meaningless form of the value of commodities, a form as seen in competition and thus reflected in the mind of the vulgar capitalist, and consequently in that of the vulgar economists.

Our analysis resulted in the discovery that the market-value (and everything said concerning it applies with the necessary modifications to the price of production) implies a surplus-profit for those who produce in any particular sphere of production under the most favorable conditions. With the exception of crises, and of over-production in general, this applies to all market-prices, no matter how much they may deviate from market-values or market-prices of production. For the market-price signifies that the same price is paid for commodities of the same kind, although they may have been produced under very different individual conditions and may have considerably different cost-prices. (We do not speak at this point of any surplus-profits due to monopolies in the strict meaning of the term, whether they are artificial or natural.)

A surplus-profit may also arise, when certain spheres of production are in a position to evade the conversion of the values of their commodities into prices of production, and thus a reduction of their profits to the average profit. We shall devote more attention to the further modifications of these two forms of surplus-profit in the part dealing with ground-rent.

CHAPTER XI.: EFFECTS OF GENERAL FLUCTUATIONS OF WAGES ON PRICES OF PRODUCTION.

LET the average composition of social capital be 80 c + 20 v, with a profit of 20%. The rate of surplus-value is then 100%. A general increase of wages, all other things remaining the same, is a reduction of the rate of surplus-value. In the case of the average capital, profit and surplus-value are identical. Let wages rise by 25%. Then the same quantity of labor, which was formerly set in motion with 20, costs 25. Instead of 80 c + 20 v + 20 p, we have then for the value of one turn-over 80 c + 25 v + 15 p. The labor set in motion by the variable capital still produces a value of 40, the same as before. If v rises from 20 to 25, then the surplus p, or s, amounts only to 15. The profit of 15 on a capital of 105 is 14 2/7%, and this would be the new average rate of profit. Since the price of production of commodities produced by the average capital coincides with their value, the price of production of these commodities would remain unchanged. The raising of wages would have brought about a reduction of profits, but no change in the value and price of the commodities.

Formerly, so long as the average profit was 20%, the price of production of the commodities produced in one period of turn-over was equal to their cost-price plus a profit of 20% on this cost-price, in other words k + kp' = k + 20 k/100. In this formula k is a variable magnitude, changing according to the value of the means of production which are incorporated in the commodities, and according to the amount of wear transferred from the fixed capital to the product. Now the price of production would amount to k + (14 2/7 k)/100.

Now let us first select a capital, whose composition is lower than the original composition of the average social capital of 80 c + 20 v (which has now been transformed into 76 4/21 c+ 23 17/21 v), for instance a capital of 50 c + 50 v. In this case, the price of production of the annual product, assuming for the sake of simplicity that the entire fixed capital passes through wear into the product and that the time of turn-over is the same as that in the first case, would have been 50 c + 50 v + 20 p, or 120, before the raising of wages. A raising of wages by 25% means for the same quantity of labor a rising of the variable capital from 50 to 62½. If the annual product were sold at the former price of production of 120, then we should have the formula 50 c + 62½ v + 7½ p, or a rate of profit of 6 2/3%. But the new average rate of profit is 14 2/7%, and since we assume all other circumstances to remain the same, this capital of 50 c + 62½ v will also have to make this profit. Now, a capital of 112½ makes a round profit of 16 1/12 at a rate of profit of 14 2/7%. Therefore the price of production of the commodities produced by this capital is now 50 c + 62½ v + 16 1/12 p = 128 7/12. In consequence of a raise in wages of 25%, the price of production of the same quantity of the same commodities has risen from 120 to 128 7/12, or more than 7%.

Vice versa, let us select a sphere of production of a higher composition than the average capital, for instance a capital of 92 c + 8 v. The original average profit in this case would still be 20, and if we assume once more that the entire fixed capital passes into the annual product, and that the time of turn-over is the same as in the first and second case, the price of production of the commodities is also 120.

In consequence of the rise of wages by 25% the variable capital for the same quantity of labor rises from 8 to 10, the cost-price of the commodities from 100 to 102, while the average rate of profit has fallen from 20% to 14 2/7%. Now 100 : 14 2/7 = 102 : 14 4/7 (approximately). The profit now falling to the share of 102 is 14 4/7. Therefore the total product sells at k + kp', or 102 + 14 4/7, or 116 4/7. The price of production has fallen from 120 to 116 4/7, or more than 3%.

Consequently, if wages are raised by 25%,

Since the price of production of the commodities of the average capital remains the same and equal to the value of the product, it follows that the sum of the prices of production of the products of all capitals remain the same and equal to the sum of the values produced by the total social capital. The increase on one side is balanced by the decrease on the other and the level of the average social capital maintained for the total social capital.

Seeing that the price of production in the second illustration rises, while it falls in the third, it is evident from these opposite effects brought about by a fall in the rate of surplus-value or by a general rise of wages that there is no prospect of any compensation in the price for the rise in wages, since the fall of the price of production in No. III cannot very well compensate the capitalist for the fall in the profit, and since the rise of the price in No. II does not prevent a fall in profit. On the contrary, in either case, whether the price rises or falls, the profit remains the same as that of the average capital whose price remains unchanged. It is the same average profit, which has fallen by 5 5/7, or about 25%, in the case of II as well as III. It follows from this, that if the price did not rise in II and fall in III, II would have to sell below and III above the new, recently reduced, average profit. It is quite evident that a rise of wages must affect a capitalist who has invested one-tenth of his capital in wages differently from one who has invested one-fourth or one-half, according to whether 50, 25, or 10 per hundred of capital are advanced for wages. An increase in the price of production on one side, and a fall on the other, according to whether a capital is below or above the average social composition, is effected only by leveling to the new reduced average profit.

Now, how would a general fall of wages, and a corresponding general rise of the rate of profit, and thus of the average profit, affect the prices of production of commodities produced by capitals diverging in opposite directions from the average social composition? We have but to reverse the foregoing statements, in order to find the answer (which Ricardo did not analyse).

I. Average capital 80 c + 20 v = 100; rate of surplus-value 100%; price of production = value of commodities = 80 c + 20 v + 20 p = 120; rate of profit 20%. Let wages fall by one-fourth. Then the same constant capital is set in motion by 15 v, instead of 20 v. We have then as the value of commodities 80 c + 15 v + 25 p = 120. The quantity of labor employed by v remains the same, only the newly created value is differently distributed between the capitalist and the laborers. The surplus-value increases from 20 to 25, and the rate of surplus-value from 20/20 to 25/15, in other words, from 100% to 166 2/3%. The profit on 95 is now 25, so that the rate of profit per 100 is 26 6/19. The composition of the capital in percentages is now 84 4/19 + 15 15/19 = 100.

II. Lower composition. Original composition, as above, 50 c + 50 v. By the fall of wages by one-fourth v is reduced to 37½, and consequently the advanced total capital to 50 c + 37½ v = 87½. Applying to this the new rate of profit of 26 6/19%, we get 100 : 26 6/19 = 87½ : 23 1/38. The same mass of commodities which formerly cost 120, now costs 87½ + 23 1/38 = 100 10/19. A fall in prices of almost 10%.

III. Higher composition. Original composition 92 c + 8 v = 100. The fall in wages by one-fourth reduces 8 v to 6 v, and the total capital to 98. Consequently 100 : 26 6/19 = 98 : 25 15/19. The price of production of the commodities, formerly 100 + 20 = 120, is now, after the fall in wages, 98 + 25 15/19 = 123 15/19. A rise by almost 4%.

We see, then, that we have but to follow the preceding development in the opposite direction with the necessary, modifications; that a general fall of wages carries with it a general rise of surplus-value, of the rate of surplus-value, and, other circumstances remaining the same, also of the rate of profit, although expressed by different proportions; a fall in the prices of production for the commodities produced by capitals of lower composition, a rise in the prices of production for commodities produced by capitals of higher composition. The result is just the reverse of that following a general rise of wages. 34 In both cases, whether of a rise or a fall, the assumption is that the working day remains the same, also the prices of the means of subsistence. Under these circumstances, a fall in wages is possible only, if wages stood higher than the normal price of labor, or if they are depressed below this price. The way in which this condition is modified, if the rise or fall of wages is due to a change in value, and consequently in the price of production of commodities usually consumed by the laborer, will be to a certain extent analysed in the part dealing with ground-rent. At this place we make for once and all the following statements:

In this entire chapter, it is assumed as a fact that there are in existence a general rate of profit, an average profit, and a conversion of values into prices of production. The question was merely in what manner a general rise or fall in wages affected the prices of production of commodities, which were assumed to exist. This is but a very secondary question compared with the important points analysed in this part. But it is the only relevant question treated by Ricardo, and we shall see that he treated even this but onesidedly and imperfectly.

CHAPTER XII.: SOME AFTER REMARKS.

CHAPTER XIII.: THE THEORY OF THE LAW.

WITH a given wage and working day, a certain variable capital, for instance of 100, represents a certain number of employed laborers. It is the index of this number. For instance, let 100 p.st. be the wages of 100 laborers for one week. If these laborers perform the same amount of necessary as of surplus-labor, in other words, if they work daily as much time for themselves as they do for the capitalist, or, in still other words, if they require as much time for the reproduction of their wages as they do for the production of surplus-value for the capitalist, then they would produce a total value of 200 p.st., and the surplus-value would amount to 100 p.st. The rate of surplus-value, s/V, would be 100%. But we have seen that this rate of surplus-value would express itself in considerably different rates of profit, according to the different volumes of constant capitals c and consequently of total capitals C. For the rate of profit is calculated by the formula s/C.

Take it that the rate of surplus-value is 100%. Now, if

In this way, the same rate of surplus-value, with the same degree of labor exploitation, would express itself in a falling rate of profit, because the material growth of the constant capital, and consequently of the total capital, implies their growth in value, although not in the same proportion.

If it is furthermore assumed that this gradual change in the composition of capital is not confined to some individual spheres of production, but occurs more or less in all, or at least in the most important ones, so that they imply changes in the organic average composition of the total capital of a certain society, then the gradual and relative growth of the constant over the variable capital must necessarily lead to a gradual fall of the average rate of profit, so long as the rate of surplus-value, or the intensity of exploitation of labor by capital, remain the same. Now we have seen that it is one of the laws of capitalist production that its development carries with it a relative decrease of variable as compared with constant capital, and consequently as compared to the total capital, which it sets in motion. This is only another way of saying that the same number of laborers, the same quantity of labor-power set in motion by a variable capital of a given value, consume in production an ever increasing quantity of means of production, such as machinery and all sorts of fixed capital, raw and auxiliary materials, and consequently a constant capital of ever increasing value and volume, during the same period of time, owing to the peculiar methods of production developing within the capitalist system. This progressive relative decrease of the variable capital as compared to the constant, and consequently to the total, capital is identical with the progressive higher organic composition of the average social capital. It is, in another way, but an expression of the progressive development of the productive powers of society, which is manifested by the fact that the same number of laborers, in the same time, convert an ever growing quantity of raw and auxiliary materials into products, thanks to the growing application of machinery and fixed capital in general, so that less labor is needed for the production of the same, or of more, commodities. This growing value and volume of constant capital corresponds to a progressive cheapening of products, although the increase in the value of the constant capital indicates but imperfectly the growth in the actual mass of use-values represented by the material of the constant capital. Every individual product, taken by itself, contains a smaller quantity of labor than the same product did on a lower scale of production, in which the capital invested in wages occupies a far greater space compared to the capital invested in means of production. The hypothetical series placed at the beginning of this chapter expresses, therefore, the actual tendency of capitalist production. This mode of production produces a progressive decrease of the variable capital as compared to the constant capital, and consequently a continuously rising organic composition of the total capital. The immediate result of this is that the rate of surplus-value, at the same degree of labor-exploitation, expresses itself in a continually falling average rate of profit. (We shall see later why this fall does not manifest itself in an absolute form, but rather as a tendency toward a progressive fall.) This progressive tendency of the average rate of profit to fall is, therefore, but a peculiar expression of capitalist production for the fact that the social productivity of labor is progressively increasing. This is not saying that the rate of profit may not fall temporarily for other reasons. But it demonstrates at least that it is the nature of the capitalist mode of production, and a logical necessity of its development, to give expression to the average rate of surplus-value by a falling rate of average profit. Since the mass of the employed living labor is continually on the decline compared to the mass of materialised labor incorporated in productively consumed means of production, it follows that that portion of living labor, which is unpaid and represents surplus-value, must also be continually on the decrease compared to the volume and value of the invested total capital. Seeing that the proportion of the mass of surplus-value to the value of the invested total capital forms the rate of profit, this rate must fall continuously.

Simple as this law appears from the foregoing statements, all of political economy has so far tried in vain to discover it, as we shall see later on. The economists saw the problem and cudgeled their brains in tortuous attempts to interpret it. Since this law is of great importance for capitalist production, it may be said to be that mystery whose solution has been the goal of the entire political economy since Adam Smith. The difference between the various schools since Adam Smith consists in their different attempts to solve this riddle. If we consider, on the other hand, that political economy up to the present has been tinkering with the distinction between constant and variable capital without ever defining it accurately; that it never separated surplus-value from profit, and never even considered profit in its purely theoretical form, that is, separated from its different subdivisions, such as industrial profit, commercial profit, interest, ground rent; that it never thoroughly analyzed the differences in the organic composition of capital, and for this reason never thought of analyzing the formation of an average rate of profit; if we consider all this, we no longer wonder at its failure to solve the riddle.

We intentionally analyze first this law, before we pass on to a consideration of the different independent categories into which profit is subdivided. The fact that this analysis is made independently of the subdivisions of profit, which fall to the share of different categories of persons, shows in itself that this law, in its general workings, is independent of those subdivisions and of the mutual relations of the resulting categories of profit. The profit to which we are here referring is but another name for surplus-value itself, which is merely observed in its relation to the total capital, instead of its relation to the variable capital from which it arises. The fall in the rate of profit therefore expresses the falling relation of surplus-value itself to the total capital, and is for this reason independent of any division of this profit among various participants.

We have seen that a certain stage of capitalist development, in which the organic composition of capital, c : v shows the proportion of 50 : 100, expresses a rate of surplus-value of 100% by a rate of profit of 66 2/3%, and that a higher stage, in which c : v shows the proportion 400:100, expresses the same rate of surplus-value by a rate of profit of only 20%. What is true of different successive stages in the same country, is also true of different contemporaneous stages of development in different countries. In an undeveloped country, in which the first-named composition of capital is the rule, the average rate of profit would be 66 2/3%, while in a country with the other, higher, stage of development, the average rate of profit would be 20%.

The difference between two national rates of profit might be eliminated, or even reversed, if labor were less productive in the less developed country, so that a larger quantity of labor would be incorporated in a smaller quantity of the same commodities, a larger exchange-value represented by a smaller use-value, so that the laborer would consume a larger portion of his time in the reproduction of his own means of subsistence, or of their value, and have less time to spare for the production of surplus-value, and consequently would perform less surplus-labor, so that the rate of surplus-value would be lower. For instance, if the laborer of the less developed country were to work two-thirds of the working day for himself, and one-third for the capitalist, then, referring to the above illustration, the same labor-power would be paid with 133 1/3 and would furnish a surplus of only 66 2/3. A constant capital of 50 would correspond to a variable capital of 133 1/3. The rate of surplus-value would then amount to 133 1/3 : 66 2/3 = 50%, and the rate of profit to 183 1/3 : 66 2/3 = about 36½%.

Since we have not analysed the different subdivisions of profit, so that they do not exist for the present so far as we are here concerned, we make the following preliminary remarks merely in order to prevent misunderstanding: It would be a mistake to measure the level of the national rate of profit by, say, the level of the national rate of interest, when comparing countries in different stages of development, especially when comparing countries with a developed capitalist production to countries, in which labor has not yet been fully subjected to capital, although the laborer may already be exploited by the capitalist, as happens, for instance, in India, where the ryot manages his farm as an independent producer, whose production, strictly so called, is not yet under the complete sway of capital, although the usurer may not only rob him of his entire surplus-labor by means of interest, but also curtail his wages, to use a capitalist term. For the interest of such stages comprises all of the profit, and more than the profit, instead of merely expressing an aliquot part of the produced surplus-value, or profit, as it does in countries with a developed capitalist production. On the other hand, the rate of interest in capitalist countries is overwhelmingly determined by conditions (loans granted by usurers to owners of large estates who draw ground-rent) which have nothing to do with profit, but which merely indicate to what extent usury appropriates ground-rent.

In countries with capitalist production in different stages of development, and consequently with capitals of different organic composition, a country with a short normal working day may have a higher rate of surplus-value (the one factor which determines the rate of profit) than a country with a long normal working day. In the first place, if the English working day of 10 hours, on account of its higher intensity, is equal to an Austrian working day of 14 hours, then dividing the working day equally in both instances, 5 hours of English surplus-labor may represent a greater value on the world-market than 7 hours of Austrian surplus-labor. In the second place, a larger portion of the English working day may represent surplus-labor than of the Austrian working day.

The law of the falling tendency of the rate of profit, which is the expression of the same, or even of a higher, rate of surplus-value, says in so many words: If you take any quantity of the average social capital, say a capital of 100, you will find that an ever larger portion of it is invested in means of production, and an ever smaller portion in living labor. Since, then, the aggregate mass of the living labor operating the means of production decreases in comparison to the value of these means of production, it follows that the unpaid labor, and that portion of value in which it is expressed, must decline as compared to the value of the advanced total capital. Or, an ever smaller aliquot part of the invested total capital is converted into living labor, and this capital absorbs in proportion to its magnitude less and less surplus-labor, although the proportion of the unpaid part of the employed labor may simultaneously grow as compared with the paid part. The relative decrease of the variable, and the relative increase of the constant, capital, while both parts may grow absolutely in magnitude, is but another expression for the increased productivity of labor.

Let a capital of 100 consist of 80 c + 20 v, and let the 20 v stand for 20 laborers. Let the rate of surplus-value be 100%, that is to say, the laborers work one-half of the day for themselves and the other half for the capitalist. Now take a less developed country, in which a capital of 100 is composed of 20 c + 80 v, and let these 80 v stand for 80 laborers. But let these laborers work two-thirds of the day for themselves, and only one-third for the capitalists. Assuming all other things to be equal, the laborers in the first case will produce a value of 40, while those in the second case will produce a value of 120. The first capital produces 80 c + 20 v + 20 s = 120; rate of profit 20%. The second capital produces 20 c+80 v+40 s=140; rate of profit 40%. In other words, the rate of profit in the second case is double that of the first case, and yet the rate of surplus-value in the first case is 100%, while it is only 50% in the second case. But a capital of the same magnitude appropriates in the first case the surplus-labor of only 20 laborers, while it appropriates that of 80 laborers in the second case.

The law of the falling tendency of the rate of profit, or of the relative decline of the appropriated surplus-labor compared to the mass of materialised labor set in motion by living labor does not argue in any way against the fact that the absolute mass of the employed and exploited labor set in motion by the social capital, and consequently the absolute mass of the surplus-labor appropriated by it, may grow. Nor does it argue against the fact that the capitals controlled by individual capitalists may dispose of a growing mass of labor and surplus-labor, even though the number of the laborers employed by them may not grow.

Take for illustration's sake a certain population of working people, for instance, two millions. Assume, furthermore, that the length and intensity of the average working day, and the level of wages, and thereby the proportion between necessary and surplus-labor, are given. In the case the aggregate labor of these two millions, and their surplus-labor expressed in surplus-value, represent always the same magnitude of values. But with the growth of the mass of the constant (fixed and circulating) capital, which this labor manipulates, the proportion of this produced quantity of values declines as compared to the value of this total capital. And the value of this capital grows with its mass, although not in the same proportion. This proportion, and consequently the rate of profit, falls in spite of the fact that the same mass of living labor is controlled as before, and the same amount of surplus-labor absorbed by the capital. This proportion changes, not because the mass of living labor decreases, but because the mass of the materialised labor set in motion by living labor increases. It is a relative decrease, not an absolute one, and has really nothing to do with the absolute magnitude of the labor and surplus-labor set in motion. The fall of the rate of profit is not due to an absolute, but only to a relative decrease of the variable part of the total capital, that is, its decrease as compared with the constant part.

The same thing which applies to any given mass of labor and surplus-labor, applies also to a growing number of laborers, and thus under the above assumptions, to any growing mass of the controlled labor in general and to its unpaid part, the surplus-labor, in particular. If the laboring population increases from two million to three million, if, furthermore, the variable capital invested in wages also rises to three million from its former amount of two million, while the constant capital rises from four million to fifteen million, then the mass of surplus-labor, and of surplus-value, under the above assumption of a constant working day and a constant rate of surplus-value, rises by 50%, that is, from two million to three million. Nevertheless, in spite of this growth in the absolute mass of surplus-labor and surplus-value by 50%, the proportion of the variable to the constant capital would fall from 2 : 4 to 3 : 15, and the proportion of the surplus-value to the total capital, expressed in millions, would be

While the mass of surplus-value has increased by one-half, the rate of profit has fallen by one-half. However, the profit is only the surplus-value calculated on the total social capital, so that its absolute magnitude, socially considered, is the same as the absolute magnitude of the surplus-value. In this case, the absolute magnitude of the profit would have grown by 50%, in spite of its enormous relative decrease compared to the advanced total capital, or in spite of the enormous fall of the average rate of profit. We see, then, that in spite of the progressive fall of rate of profit, there may be an absolute increase of the number of laborers employed by capital, an absolute increase of the labor set in motion by it, an absolute increase of the mass of surplus-labor absorbed, a resulting absolute increase of the produced surplus-value, and consequently an absolute increase in the mass of the produced profit. And this increase may be progressive. And it may not only be so. On the basis of capitalist production, it must be so, aside from temporary fluctuations.

The capitalist process of production is essentially a process of accumulation. We have shown that the mass of values, which must be simply reproduced and maintained, increases progressively with the development of capitalist production to the extent that the productivity of labor grows, even if the employed labor-power should remain constant. But the development of social productivity carries with it a still greater increase of the produced use-values, of which the means of production form a part. And the additional labor, whose appropriation reconverts this additional value into capital, does not depend on the value, but on the mass of these means of production (including the means of subsistence), because the laborer in the productive process is not operating with the exchange-value, but with the use-value of the means of production. Accumulation itself, however, and the concentration of capital that goes with it, is a material means of increasing the productive power. Now, this growth of the means of production includes the increase of the laboring population, the creation of a laboring population which corresponds to the surplus-capital or even exceeds its general requirements, leading to an overpopulation of working people. A momentary excess of the surplus-capital over the laboring population controlled by it would have a twofold effect. It would, on the one hand, mitigate the conditions, which decimate the offspring of the laboring class and would facilitate marriages among them, by raising wages. This would tend to increase the laboring population. On the other hand, it would employ the methods by which relative surplus-value is created (introduction and improvement of machinery) and thereby create still more rapidly an artificial relative overpopulation, which in its turn would be a hothouse for the actual propagation of its numbers, since under capitalist production poverty propagates its kind. The nature of the capitalist process of accumulation, which process is but an element in the capitalist process of production, implies as a matter of course that the increased mass of means of production, which is to be converted into capital, must always find on hand a corresponding increase, or even an excess, of laboring people for exploitation. The progress of the process of production and accumulation must, therefore, be accompanied by a growth of the mass of available and appropriated surplus-labor, and consequently by a growth of the absolute mass of profit appropriated by the social capital. But the same laws of production and accumulation increase the volume and value of the constant capital in a more rapid progression than those of the variable capital invested in living labor. The same laws, then, produce for the social capital an increase in the absolute mass of profit and a falling rate of profit.

We leave out of consideration the fact that the same amount of values represents a progressively increasing mass of use-values and enjoyments to the extent that the capitalist process of production carries with it a development of the productive power of social labor, a multiplication of the lines of production, and an increase of products.

The development of capitalist production and accumulation lifts the processes of labor to a higher scale and gives them greater dimensions, which imply larger investments of capital for each individual establishment. A growing concentration of capitals (accompanied by a growing number of capitalists, though not to the same extent) is therefore one of the material requirements of capitalist production as well as one of the results produced by it. Hand in hand with it, and mutually interacting, goes a progressive expropriation of the more or less direct producers. It is, then, a matter of course for the capitalists that they should control increasing armies of laborers (no matter how much the variable capital may relatively decrease in comparison to the constant capital), and that the mass of surplus-value, and of profit, appropriated by them, should grow simultaneously with the fall of the rate of profit, and in spite of it. The same causes which concentrate masses of laborers under the control of capitalists, are precisely those which also swell the mass of fixed capital, auxiliary and raw materials in a growing proportion as compared to the mass of the employed living labor.

It requires but a passing notice at this point, that, given a certain laboring population, the mass of surplus-value, and therefore the absolute mass of profit, must grow if the rate of surplus-value increases by a prolongation or intensification of the working day, or by a lowering of the value of wages through a development of the productive power of labor, and must do so in spite of the relative decrease of the variable capital compared to the constant.

The same development of the productive power of social labor, the same laws, which express themselves in a relative fall of the variable as compared to the total capital and in a correspondingly hastened accumulation, while this accumulation in its turn becomes the starting point of a further development of the productive power and of a further relative fall of the variable capital, this same development manifests itself, aside from temporary fluctuations, by a growing increase of the employed total labor-power, a growing increase of the absolute mass of surplus-value, and consequently of profits.

Now, in what form must this two-faced law with the same causes for a decrease of the rate of profits and a simultaneous increase of the absolute mass of profits show itself? A law based on the fact that under certain conditions the appropriated mass of surplus-labor, and consequently of surplus-value, increases, and that, so far as the total capital is concerned, or the individual capital as an aliquot part of the total capital, profit and surplus-value are identical magnitudes?

Take that aliquot part of capital which is the basis of our calculation of the rate of profit, for instance 100. These 100 illustrate the average composition of the total capital, say 80 c + 20 v. We have seen in the second part of this volume, that the average rate of profit is determined, not by the particular composition of individual capital, but by the average composition of social capital. If the variable capital decreases as compared to the constant, or to the total capital, then the rate of profit, or the relative magnitude of surplus-value calculated on the total capital, falls even though the intensity of exploitation were to remain the same, or even to increase. But it is not this relative magnitude alone which falls. The magnitude of the surplus-value or profit absorbed by the total capital of 100 also falls absolutely. At a rate of surplus-value of 100%, a capital of 60 + 40 produces a mass of surplus-value and profit amounting to 40; a capital of 70 c + 30 v a mass of profit of 30; a capital of 80 c + 20 v produces only 20 of profit. This fall refers to the mass of surplus-value and thus of profit, and is due to the fact that the total capital of 100, with the same intensity of labor exploitation, employs less living labor, sets in motion less labor-power, and therefore produces less surplus-value. Taking any aliquot part of the social capital, this is, of capital of average composition, as a standard by which to measure surplus-value—and this is done in all calculations of profit—a relative fall of surplus-value is identical with its absolute fall. The rate of profit sinks in the above cases from 40% to 30% and 20%, because the mass of surplus-value, and of profit, produced by the same capital falls absolutely from 40 to 30 and 20. Since the magnitude of the value of capital, by which the surplus-value is measured, is given as 100, a fall in the proportion of surplus-value to this given magnitude can be only another expression for the fact that surplus-value and profit decrease absolutely. This is, of course, a tautology. But we have demonstrated that the nature of the capitalist process of production brings about this decrease.

On the other hand, the same causes which bring about an absolute decrease of surplus-value and profit on a given capital, and consequently in the percentage of the rate of profit, produce an increase of the absolute mass of surplus-value and profit appropriated by the total capital (that is, by the capitalists as a whole). How can this be explained, and what is the only way in which this can be explained, or what are the conditions on which this apparent contradiction is based?

While any aliquot part, any 100 of the social capital, any 100 of average social composition, is a given magnitude, for which a fall in the rate of profit implies a fall in the absolute magnitude of profit, just because the capital which serves as a standard of measurement is a constant magnitude, the magnitude of the social capital, on the other hand, as well as that of the capital in the hands of individual capitalists, is variable, and in keeping with our assumptions it must vary inversely to the decrease of its variable portion.

In our former illustration, when the percentage of composition was 60 c + 40 v, the corresponding surplus-value and profit was 40, and the rate of profit 40%. Take it that the total capital in this stage of composition was one million. In that case the total surplus-value, and total profit, amounted to 400,000. Now, if the composition changes later to 80 c + 20 v, while the degree of labor exploitation remains the same, then the surplus-value and profit for each 100 is 20. But as we have demonstrated that the absolute mass of surplus-value and profit increases in spite of the fall of the rate of profit, in spite of the decrease in the production of surplus-value by a capital of 100, that it grows, say, from 400,000 to 440,000, there is no other way in which this could be brought about than by a growth of the total capital to 2,200,000 to the extent that this new composition developed. The mass of the total capital set in motion has risen by 220%, while the rate of profit has fallen by 50%. If the total capital had only been doubled, it could have produced no more surplus-value and profit with a rate of profit of 20% than the old capital of 1,000,000 at a rate of 40%. If it had grown to less than twice its old size, it would have produced less surplus-value or profit than the old capital of 1,000,000 which, with its former composition, would have had to grow from 1,000,000 to no more than 1,100,000, in order to raise its surplus-value from 400,000 to 440,000.

We meet here once more the previously analysed law, that the relative decrease of the variable capital, or the development of the productive power of labor, requires an increasing mass of total capital for the purpose of setting in motion the same quantity of labor-power and absorbing the same quantity of surplus-labor. Consequently the possibility of a relative surplus of laboring people develops to the extent that capitalist production advances, not because the productive power of social labor decreases, but because it increases. Relative overpopulation does not arise out of an absolute disproportion between labor and means of subsistence, or of means for the production of these means of existence, but out of a disproportion due to the capitalist exploitation of labor, a disproportion between the growing increase of capital and its relatively decreasing demand for an increase of population.

A fall in the rate of profit by 50% means its fall by one-half. If the mass of profit is to remain the same, the capital must be doubled. In order that the mass of profit made at a declining rate of profit may remain the same as before, the multiplier indicating the growth of the total capital must be equal to the divisor indicating the fall of the rate of profit. If the rate of profit falls from 40 to 20, the total capital must rise at the rate of 20 to 40, in order that the result may remain the same. If the rate of profit had fallen from 40 to 8, the capital would have to increase at the rate of 8 to 40, or five times its value. A capital of 1,000,000 at a rate of 40% produces 400,000, and a capital of 5,000,000 at a rate of 8% likewise produces 400,000. This applies, so long as the result is to remain the same. But if the result is to be higher, then the capital must grow at a faster rate than the rate of profit falls. In other words, in order that the variable portion of the total capital may not only remain the same, but may also increase absolutely, although its percentage in the total capital falls, the total capital must grow at a higher rate than the percentage of the variable capital falls. It must grow at such a rate that it requires in its new composition not merely the same old variable capital, but more than it for the purchase of labor-power. If the variable portion of a capital of 100 falls from 40 to 20, the total capital must rise higher than 200, in order to be able to employ a larger variable capital than 40.

Even if the mass of the exploited laboring population were to remain constant, and only the length and intensity of the working day to increase, the mass of the invested capital would have to increase, since it must rise for the mere purpose of employing the same mass of labor under the old conditions of exploitation as soon as the composition of capital varies.

In short, the same development of the social productivity of labor expresses itself in the course of capitalist production on the one hand in a tendency to a progressive fall of the rate of profit, and on the other hand in a progressive increase of the absolute mass of the appropriated surplus-value, or profit; so that on the whole a relative decrease of variable capital and profit is accompanied by an absolute increase of both. This twofold effect, as we have seen, can express itself only in a growth of the total capital at a ratio more rapid than that expressed by the fall in the rate of profit. In order that an absolutely increased variable capital may be employed in a capital of higher composition, that is, a capital in which the constant capital has relatively increased still more than the variable, the total capital must one only grow in proportion to its higher composition, but even still more rapidly. It follows, then, that an ever larger quantity of capital is required in order to employ the same, and still more an increased amount of labor-power, to the extent that the capitalist mode of production develops. The increasing productivity of labor thus creates necessarily and permanently an apparent overpopulation of laboring people. If the variable capital forms only one-sixth of the total capital instead of one-half, as before, then the total capital must be trebled in order to employ the same amount of labor-power. And if the labor-power to be employed is doubled, then the total capital must be multiplied by six.

Political economy has so far been unable to explain the law of the falling tendency of the rate of profit. So it pointed as a consolation to the increasing mass of profit, the increase in the absolute magnitude of profit for the individual capitalist as well as for the social capital, but even this consolation was based on mere commonplaces and probabilities.

It is simply a tautology to say that the mass of profit is determined by two factors, namely first the rate profit, and secondly by the mass of capital invested at this rate. It is therefore but a corollary of this tautology to say that there is a possibility for the increase of the mass of profit even though the rate of profit may fall at the same time. This does not help us to get one step farther, since there is also a possibility that the capital may increase without resulting in an increase of the mass of profit, and that it may even increase while the mass of profit is already falling. For 100 at 25% make 25, while 400 at 5% make only 20. 35 But if the same causes, which bring about a fall in the rate of profit, promote the accumulation, that is, the formation of additional capital, and if each additional capital employs additional labor and produces additional surplus-value; when, on the other hand, the mere fall in the rate of profit implies the fact that the constant capital, and with it the total old capital, have increased, then this process ceases to be mysterious. We shall see later, to what falsifications of calculations some people have recourse in order to deny the possibility of an increase in the mass of profits while the rate of profits is simultaneously decreasing.

We have shown that the same causes, which bring about a tendency of the average rate of profits to fall, necessitate also an accelerated accumulation of capital and consequently an increase in the absolute magnitude, or total mass, of the surplus-labor (surplus-value, profit) appropriated by it. Just as everything is reversed in competition, and thus in the consciousness of its agents, so is also this law, this internal and necessary connection between two apparent contradictions. It is evident, within the proportions indicated above, that a capitalist disposing of a large capital will receive a larger mass of profits than a small capitalist making apparently high profits. A superficial observation of competition shows furthermore that under certain circumstances, when the greater capitalist wishes to make more room for himself on the market by pushing aside the smaller ones, as happens in times of commercial crises, he makes a practical use of this, that is, he lowers his rate of profit intentionally in order to crowd the smaller ones off the field. Particularly merchant's capital, as we shall show at length later on, shows symptoms, which seem to attribute the fall in profits to an expansion of the business, and thus of capital. We shall later on give a scientific expression for this false conception. Similar superficial observations result from the comparison of rates of profit made in some particular lines of business, according to whether they are subject to free competition or to monopoly. The utterly shallow conception existing in the heads of the agents of competition is found in our Roscher, namely the idea that a reduction of the rate of profits is "more prudent and humane." The fall in the rate of profit is in this case attributed to an increase of capital, it appears as a consequence of this increase, and of the resultant calculation of the capitalist that the mass of profits to be pocketed by him will be greater at a smaller rate of profits. This entire conception (with the exception of that of Adam Smith, which we shall mention later) rests on the utter misapprehension of what the average rate of profit represents and on the crude idea that prices are indeed determined by adding a more or less arbitrary amount of profit to the actual value of the commodities. Crude as these ideas are, they arise necessarily out of the inverted aspect which the immanent laws of capitalist production represent under competition.

The law that the fall in the rate of profit due to the development of the productive powers is accompanied by an increase in the mass of profit expresses itself furthermore in the fact that a fall in the price of commodities produced by capital is accompanied by a relative increase of the masses of profit contained in them and realised by their sale.

Since the development of the productive powers and the higher composition of capital corresponding to it set in motion an ever increasing quantity of means of production with an ever decreasing quantity of labor, every aliquot part of the total product, every single commodity, or every particular quantity of commodities in the total mass of products absorbs less living labor, and also contains less materialised labor, both as to the wear and tear of fixed capital and to the raw and auxiliary materials consumed. Every single commodity, then, contains a smaller amount of labor materialised in means of production and of labor newly added during production. Hence the price of the individual commodity falls. The mass of profits contained in the individual commodities may nevertheless increase, if the rate of the absolute or relative surplus-value grows. The commodity then contains less newly added labor, but its unpaid portion grows over its paid portion. However, this is the case only within certain limits. In the course of the development of production, with the enormously growing absolute decrease of the amount of living labor newly embodied in the individual commodities, the mass of unpaid labor contained in them will likewise decrease absolutely, however much it may have grown as compared to their paid portion. The mass of profit on each individual commodity will decrease considerably with the development of the productive power of labor, in spite of the increase of the rate of surplus-value. And this reduction, the same as the fall in the rate of profits, is only delayed by the cheapening of the elements of constant capital and the other circumstances mentioned in the first part of this volume, which increase the rate of profit at a stable, or even falling, rate of surplus-value.

To say that the price of the individual commodities falls, which together make up the total product of the capital, is simply to say that a certain quantity of labor is realised in a larger quantity of commodities, so that each individual commodity contains less labor than before. This is the case even if the price of one of the parts of constant capital, such as raw material, etc., should rise. With the exception of a few cases (for instance, if the productive power of labor cheapens all the elements of constant and variable capital uniformly) the rate of profit will fall in spite of the increased rate of surplus-value, 1), because even a larger unpaid portion of the smaller total amount of newly added labor is smaller than a smaller aliquot portion of unpaid labor was in the former large amount of total labor, and 2), because the higher composition of the capital is expressed through the individual commodity by the fact that that portion of its value, in which newly added labor is materialised, decreases as compared to that portion of its value, which represents raw material, auxiliary material, and wear and tear of fixed capital. This change in the proportions of the various component parts of the price of the individual commodities, the decrease of that portion of their price, in which newly added labor is materialised, and the increase of that portion, in which formerly materialised labor is represented, is that form which expresses through the price of the individual commodities the decrease of the variable capital as compared to the constant capital. To the extent that this decrease is absolute for a certain amount of capital, for instance 100, it is also absolute for every individual commodity as an aliquot part of the reproduced capital. However, the rate of profit, if calculated merely on the elements of the price of the individual commodity, would be different from what it actually is. The reason for this is as follows:

This demonstrates once more how important it is under the capitalist mode of production that the individual commodities or the commodity-product of a certain period should not be considered as isolated by themselves, as mere commodities, but as products of advanced capital and in their relation to the total capital, which produces them.

Although the rate of profit must be calculated by measuring the mass of the produced and realised surplus-value by the consumed portion of capital reappearing in the commodities as well as by the sum of this portion plus that portion of capital which, though not consumed, is employed and continues to serve in production, the mass of profit cannot be equal to anything but the mass of profit, or surplus-value, contained in the commodities themselves and to be realised by their sale.

If the productivity of industry increases, the prices of the individual commodities fall. There is less paid and unpaid labor contained in them. Let the same labor produce, say, thrice, its former product. Then the individual product requires two-thirds less labor. And since the profit can constitute but a portion of the amount of labor congealed in the individual commodities, the mass of profit in the individual commodities must decrease. And this must hold good, within certain limits, even if the rate of surplus-value should rise. In any case, the mass of profits on the total product does not fall below the original mass of profits so long as the capital employs the same number of laborers at the same degree of exploitation. (This may also take place, if fewer laborers are employed at a higher rate of exploitation.) For to the same extent that the mass of profit on the individual product decreases does the number of products increase. The mass of profits remains the same, only it is distributed differently over the total amount of commodities. Nor does this alter the division of the amount of value created by newly added labor between the laborers and capitalists. The mass of profit cannot increase, so long as same amount of labor is employed, unless the unpaid surplus-labor increases, or, supposing the intensity of exploitation to remain the same, unless the number of laborers grows. Or, both of these causes may, of course, combine to produce this result. In all these cases, which, however, according to our assumption, presuppose an increase of the constant capital as compared to the variable and an increase in the magnitude of the total capital, the individual commodity contains a smaller mass of profit and the rate of profit falls even if it is calculated on the individual commodity. A given quantity of additional labor is materialised in a larger quantity of commodities. The price of the individual commodities falls. Abstractly speaking, the rate of profit may remain the same, even though the price of the individual commodity may fall as a result of an increase in the productivity of labor and a simultaneous increase in the number of these cheaper commodities, for instance, if the increase in the productivity of labor extended its effects uniformly and simultaneously to all the elements of the commodities, so that the total price of the commodities would fall in the same proportion in which the productivity of labor would increase, while on the other hand the mutual relations of the different elements of the price of commodities would remain the same. The rate of profit might even rise, if a rise in the rate of surplus-value were accompanied by a considerable reduction in the value of the elements of constant, and particularly of fixed, capital. But in reality, as we have seen, the rate of profit will fall in the long run. In any case, a fall in the price of any individual commodity does not by itself give a clue to the rate of profit. Everything depends on the magnitude of the total capital invested in its production. For instance, if the price of one yard of fabric falls from 3 sh. to 1 2/3 sh.; if we know that it contained before this reduction in price 1 2/3 sh. worth of constant capital, yarn, etc., 2/3 sh. wages, and 1/3 sh. profit, while it contains after this reduction 1 sh. of constant capital, 1/3 sh. of wages, and 1/3 sh. of profit, we cannot tell whether the rate of profit has remained the same or not. This depends on the question, whether the advanced total capital has increased, and how much, and how many yards of fabric more it produces in a given time.

This phenomenon arising from the nature of the capitalist mode of production, namely, that an increase in the productivity of labor implies a fall in the price of the individual commodity, or of a certain mass of commodities, an increase in the number of commodities, a reduction of the mass of profit in the individual commodity and of the rate of profit on the aggregate of commodities, an increase of the mass of profit in the total quantity of commodities, this phenomenon shows itself on the surface only in a reduction of the mass of profit in the individual commodities, in a fall of their prices, in an increase of the mass of profits in the augmented number of commodities as a whole, which have been produced by the total capital of society or by that of the individual capitalist. It is then imagined that the capitalist adds less profits to the price of the individual commodities on his own free volition and makes up for it by the returns on a greater number of commodities produced by him. This conception rests upon the idea of profit upon alienation, which in its turn is deduced from the ideas of merchant's capital.

We have seen previously, in parts four and seven of Book I, that the growth in the mass of commodities resulting from the productivity of labor and the consequent cheapening of the commodities as such (unless these commodities become determining elements in the price of labor-power) do not affect the proportion between paid and unpaid labor in the individual commodities, in spite of the fall in price.

Since everything appears inverted under competition, the individual capitalist may imagine: 1) That he is reducing his profit on the individual commodity by cutting its price, but still making a greater profit on account of the larger quantity of commodities which he is selling; 2) that he is fixing the price of the individual commodities and determining the price of the total product by multiplication, while the original process is really one of division (see Book I, chapter XII) and the multiplication is correct only in a secondary way, being based on that division. The vulgar economist does practically no more than to translate the queer concepts of the capitalists, who are in the thralls of competition, into a more theoretical and generalising language and to attempt a vindication of the correctness of those conceptions.

Practically, a fall in the prices of commodities and a rise in the mass of profits contained in the augmented mass of these cheapened commodities is but another expression for the law of the falling rate of profit with a simultaneous increase in the mass of profits.

The analysis of the extent to which a falling rate of profit may coincide with rising prices does not belong in this chapter any more than that of the point previously discussed in volume I, chapter XII, concerning relative surplus-value. A capitalist working with improved methods of production that have not yet become general sells below the market-price, but above his individual price of production. In this way his rate of profit rises until competition levels it down. During this leveling period the second requisite puts in its appearance, namely the expansion of the invested capital. According to the degree of this expansion the capitalist will be enabled to employ a part of his former laborers under the new conditions, and eventually all of them or more, in other words, he will be enabled to produce the same or a greater mass of profits.

CHAPTER XIV.: COUNTERACTING CAUSES.

IF we consider the enormous development of the productive powers of labor, even comparing but the last 30 years with all former periods; if we consider in particular the enormous mass of fixed capital, aside from machinery in the strict meaning of the term, passing into the process of social production. as a whole, then the difficult, which has hitherto troubled the vulgar economists, namely that of finding an explanation for the falling rate of profit, gives way to its opposite, namely to the question; How is it that this fall is not greater and more rapid? There must be some counteracting influences at work, which thwart and annul the effects of this general law, leaving to it merely the character of a tendency. For this reason we have referred to the fall of the average rate of profit as a tendency to fall.

The following are the general counterbalancing causes:
