High Rents and Land Use Regulation

The Federal Reserve’s Devin Bunten has posted Is the Rent Too High? Aggregate Implications of Local Land-Use Regulation. It is a technical paper about an important subject. It has implications for those who are concerned about the lack of affordable housing in high-growth areas. The abstract reads,

Highly productive U.S. cities are characterized by high housing prices, low housing stock growth, and restrictive land-use regulations (e.g., San Francisco). While new residents would benefit from housing stock growth in cities with highly productive firms, existing residents justify strict local land-use regulations on the grounds of congestion and other costs of further development. This paper assesses the welfare implications of these local regulations for income, congestion, and urban sprawl within a general-equilibrium model with endogenous regulation. In the model, households choose from locations that vary exogenously by productivity and endogenously according to local externalities of congestion and sharing. Existing residents address these externalities by voting for regulations that limit local housing density. In equilibrium, these regulations bind and house prices compensate for differences across locations. Relative to the planner’s optimum, the decentralized model generates spatial misallocation whereby high-productivity locations are settled at too-low densities. The model admits a straightforward calibration based on observed population density, expenditure shares on consumption and local services, and local incomes. Welfare and output would be 1.4% and 2.1% higher, respectively, under the planner’s allocation. Abolishing zoning regulations entirely would increase GDP by 6%, but lower welfare by 5.9% because of greater congestion.

The important sentence from the abstract is that “Welfare and output would be 1.4% and 2.1% higher, respectively, under the planner’s allocation.” Those are significant effects when we are talking about  real people and real places. The introduction provides a bit more context for the study:

Neighborhoods in productive, high-rent regions have very strict controls on housing development and very limited new housing construction. Home to Silicon Valley, the San Francisco Bay Area is the most productive and most expensive metropolitan region in the country, and yet new housing construction has been very slow, especially in contrast to less-productive large cities like Houston, Texas. The evidence suggests that this slow-growth environment results from locally determined regulatory constraints. Existing residents justify these constraints by appealing to the costs of new development, including increased vehicle traffic and other types of congestion, and claim that they see few, if any, of the benefits from new development. However, the effects of local regulation extend beyond the local regulating authorities: regions with highly regulated municipalities experience less-elastic housing supply. (2, footnotes omitted)

The bottom line, as far as I am concerned, is that localities that are attempting to deal with their affordable housing problems have to directly address how they go about their zoning. If the zoning does not support housing construction, then no amount of affordable housing incentives will address the demand for housing in high growth places like NYC and San Francisco.

The Dense State of NYC’s Housing

NYU’s Furman Center released its State of New York City’s Housing and Neighborhoods in 2014. I found its discussion of urban density to be the most notable aspect of this nexcellent and data-rich annual report. The discussion on density concludes,

The renewed attractiveness of New York City since the 1970s means population will likely keep increasing, and so will population and housing density. In 2010, few other U.S. cities had any neighborhoods that matched the density experienced by the typical New Yorker. Yet, by recent historical standards, today’s density levels are not extreme. In recent years, the typical New Yorker lived in a lower-density neighborhood than the typical New Yorker in 1970, as population growth in the city since 1980 was focused in moderate-density neighborhoods. Further, while great disparities in education and crime across neighborhoods exist, these differences are not generally associated with density levels.

High density cities like New York are playing an increasingly important role in the economy as drivers of productivity and innovation. This means the accessibility of the city to new residents is important both for New Yorkers and the nation. We have demonstrated that significant numbers of new residents can be accommodated without elevating density to levels above what the city has historically experienced, and that high-density neighborhoods do not perform lower on key quality of life indicators. City officials will need to ensure that neighborhoods have sufficient infrastructure to accommodate their new residents. (20)

This last point is key: density is not a problem so long as the appropriate infrastructure is built to support it. And while current residents are concerned about the impact of local increases in density, the city as a whole benefits from the increased economic activity and cultural creativity that comes along with heightened density. The De Blasio Administration knows this. Other local elected officials should sign on to increased density along with thoughtful zoning and infrastructure policies.

As a final note, I would compare the transparent acknowledgement of the report’s financial sponsors in the front matter with the much less transparent acknowledgment found in Harvard’s Joint Center for Housing Studies State of the Nation’s Housing 2015 report that I blogged about yesterday.
