The Land Use Report of the President

The Economic Report of the President contains an important analysis of local land use policies in a section titled “Constraints on Housing Supply:”

Supply constraints provide a structural challenge in the housing market, particularly in high-mobility, economically vibrant cities. When housing supply is constrained, it has less room to expand when demand increases, leading to higher prices and lower affordability. Limits on new construction can, in turn, impede growth in local labor markets and restrain aggregate output growth. Some constraints on the supply of housing come from geography, while others are man-made. Constraints due to land-use regulations, such as minimum lot size requirements, height restrictions, and ordinances prohibiting multifamily housing, fall into the man-made category and thus could be amended to support more inclusive growth. While these regulations can sometimes serve legitimate purposes such as the protection of human health and safety and the prevention of environmental degradation, land-use regulations can also be used to protect vested interests in housing markets.

Gyourko and Molloy (2015) argue that supply constraints have worsened in recent decades, in large part due to more restrictive land-use regulations. House prices have risen faster than construction costs in real terms, providing indirect evidence that land-use regulations are pushing up the price of land.

According to Gyourko and Molloy (2015), between 2010 and 2013, real house prices were 55 percent above real construction costs, compared with an average gap of 39 percent during the 1990s. Several other studies note that land-use regulations have been increasing since roughly 1970, driving much of the real house appreciation that has occurred over this time (Glaeser, Gyourko, and Saks 2005; Glaeser and Ward 2009; Been et al. 2014). This pattern is noteworthy because of the positive correlation between cities’ housing affordability and the strictness of their land use regulations, as measured by the Wharton Residential Land Use Regulation Index (Gyourko et al. 2008). Cities to the lower right of the figure which include Boston and San Francisco, have stringent land-use regulations and low affordability. Cities at the upper left, which include St. Louis and Cleveland, have low regulation and high affordability. Supply constraints by themselves do not make cities low in affordability. Rather, the less responsive housing supply that results from regulation prevents these cities, which often happen to be desirable migration destinations for workers looking for higher-paying jobs, from accommodating a rise in housing demand.

In addition to housing affordability, these regulations have a range of impacts on the economy, more broadly. Reduced housing affordability—whether as an ancillary result of regulation or by design—prevents individuals from moving to high productivity areas. Indeed, empirical evidence from Molloy, Smith, and Wozniak (2012) indicates that migration across all distances in the United States has been in decline since the middle of the 1980s. This decreased labor market mobility has important implications for intergenerational economic mobility (Chetty et al. 2014) and also was estimated in recent research to have held back current GDP by almost 10 percent (Hsieh and Moretti 2015).

Land-use regulations may also make it more difficult for the housing market to accommodate shifts in preferences due to changing demographics, such as increased demand for modifications of existing structures due to aging and increased demand for multifamily housing due to higher levels of urbanization (Goodman et al. 2015). A number of Administration initiatives, ranging from the Multifamily Risk-Sharing Mortgage program to the Affirmatively Furthering Fair Housing rule, try to facilitate the ability of housing supply to respond to housing demand. Ensuring that zoning and other constraints do not prevent housing supply from growing in high productivity areas will be an important objective of Federal as well as State and local policymakers.

It is important in itself that the Executive Branch of the federal government has acknowledged the outsized role that local land use policies play in the economy. But the policies that the Obama Administration has implemented don’t go very far in addressing the problems caused by myopic land use policies that favor vested interests. The federal government can be far more aggressive in rewarding local land use policies that support equitable housing and economic development goals. It can also punish local land use policies that hinder those goals.

Edward Glaeser and Joseph Gyourko get much of the credit for demonstrating the effect that local land use policies have on federal housing policy. Now that the President is listening to them, we need Congress to pay attention too. This could be one of those rare policy areas where Democrats and  Republicans can find common ground.
