       | rest on people who claim that the laws of supply and demand fail

           | don't think any particular holder of real estate is too
           | worried about it. You can sit on vacant property to your

           | company, will likely meet or exceed what you're looking to
           | get out of it.
           | 
           | Real estate also has the handy benefit in it's basically

       | Also, I am not sure whether comparing to median value of
       | constraint index (e.g. Wharton residential land use regulation
       | index) is a particularly good way to categorizing metros into
       | constrained and unconstrained, since it's hard to know which
       | specific constraints of the "regulatory hydra" are important for
       | future development (https://twitter.com/TheJakeSchmidt/status/157
       | 220787234744729...). One metro may need to reduce minimum lot
       | sizes to allow the next increment of development, whereas another
       | metro may need to allow lot mergers and relax density limits
       | instead.
       | 
       | So I think this paper is basically concluding that land use
       | constraints are harder to measure than income growth.
