Why has homebuilding slowed even in high-demand, high-price markets?
Core argument: The intensity of U.S. housing production has dropped substantially over time, especially in expanding Sunbelt markets that were once housing market superstars, with Miami now resembling Los Angeles in its pace of unit production.
The key driver appears to be that the intensity of housing production has dropped substantially over time, especially in many expanding Sunbelt markets that were once housing market superstars. There is a marked convergence in the pace of housing unit production across markets throughout the country: Miami has become far more like Los Angeles. Our analysis suggests that there has been an economically important flattening of the empirical housing supply curve in these places. [As in] other markets on the coasts and in declining industrial centers in earlier decades. Within metropolitan areas across the country, we now build less often in the highest demand areas. We also found relatively weak relationships between density and the construction of single family detached housing. To us, this suggests that insiders increasingly control regulations to protect their own rents. If so we should expect to see a decreasing link between high prices and new construction, which is exactly what the data shows.
