The Economic Implications of Housing Supply

A new paper with the above title by urban economists Edward Glaeser and Joseph Gyourko provides more evidence to back up the Antiplanner’s recent paper on the New Feudalism. One of the major points of that paper was that the Obama administration’s plan to force suburbs to relax zoning codes to allow higher density housing is not the solution to housing affordability problems.

Glaeser and Gyourko point out that housing is affordable in most of the country despite zoning. In some parts of the country, however, “property rights have essentially been reassigned from existing land owners to wider communities, which have chosen to substantially reduce the amount of new building.” The result is that the supply curve for housing, which is nearly horizontal (meaning changes in demand have little effect on prices) in communities with traditional zoning, becomes very steep in the overly regulated communities (meaning small changes in demand can result in large changes in prices, i.e., prices will be more volatile).
