This is a writeup of a shallow investigation, a brief look at an area that we use to decide how to prioritize further research.
In a nutshell
What is the problem?
Local laws often prohibit the construction of dense new housing, which drives up prices, especially in a few large high-wage metropolitan areas. The increased prices transfer wealth from renters to landowners and push people away from centers of economic activity, which reduces their wages and total economic output, likely by a very large amount.
What are possible interventions?
Local organizations could directly advocate for municipal governments to permit more and denser development. Changes in the local decision-making process (e.g. “zoning budgets”) could increase the likelihood of policy outcomes that allow higher density. Shifting decision-making to larger administrative bodies, such as state governments, could reduce the influence of the narrow local interests that most often impose barriers to permitting additional density. We don’t have a strong sense of how a new funder might best promote these outcomes.
Who else is working on it?
Some major foundations support a variety of work related to affordable (subsidized) housing, but they usually do not focus on increasing supply more generally. Some local organizations support increased supply and allowing denser development, but these organizations are generally quite small.
What is the problem?
Local governments in the United States typically have a variety of laws that limit what kinds of building can be built in different places, including limits on how much total built floor area any given lot is allowed to contain.[1]“City planners generally initiate zoning proposals, which then must be approved by city council members. Although some land use regulations are made at the state level in the U.S., most such issues are handled locally. In Canada, there is more provincial involvement, especially in Ontario. On … Continue reading Our understanding is that one effect of these policies is to prevent the construction of dense housing.[2]GiveWell’s non-verbatim summary of a conversation with Gabriel Metcalf, March 31, 2014: “Zoning and other regulatory limits on construction are the main reason that there has not been more construction in response to the demand for housing in the Bay Area.” GiveWell’s non-verbatim summary … Continue reading This drives up prices,[3]Glaeser and Gyourko 2008, Pg 79: “[B]asic economics and the data are consistent with local land-use regulations having a dramatic impact on U.S. housing markets.

Places that have met high … Continue reading and makes many people less productive by making it unaffordable for them to live close to centers of economic activity.[4]GiveWell’s non-verbatim summary of a conversation with David Schleicher, May 15, 2014: One of the major effects of liberalizing land use would be: “Accelerating the rate of economic growth by allowing people to cluster more densely in highly productive places and share ideas. This effect could … Continue reading
Economists Edward Glaeser, Joseph Gyourko, and Raven Saks have compared the sale price of housing to the combined cost of construction and price of land in different cities to estimate the level of regulatory “tax” that drives up prices by limiting construction.[5]“Because the degree of housing market regulation is so difficult to measure, we adopt an alternative approach that is based on neoclassical economic theory. With or without regulation, that theory predicts that competition among builders will ensure that prices equal average costs. In unregulated … Continue reading They estimate that land use regulations increase housing prices by 19% in Boston, 34% in Los Angeles, 12% in New York, 53% in San Francisco, and 22% in Washington, DC, while estimates for other areas are generally much smaller (close to zero).[6] METROPOLITAN AREA HEDONIC PRICE OF LAND ($/SQUARE FOOT) AVERAGE HOUSE VALUE ($) ZONING TAX/HOUSE … Continue reading The real estate website Zillow estimates that total residential rents in those metropolitan areas are around $120 billion/year, which implies that the “tax” on renters in those metropolitan areas amounts to roughly $30 billion per year.[7]We estimated this figure by multiplying Glaeser et al. 2005’s estimates of the zoning tax for five major metro areas which we guess account for the majority of the problem by estimates for the total amount of rent paid in these cities, from Total Rent Paid 2013 and 2014, Zillow: CITY RENT … Continue reading However, these figures do not represent straightforward welfare costs, since the “regulatory taxes” would be paid as inflated rents to owners. A rough back of the envelope calculation drawing on the same Glaeser et al. 2005 figures suggests that foregone housing consumption in the five large supply-restricted metropolitan areas might add up to over $600 billion in value, and that the deadweight loss in those areas might be around $100 billion.[8]According to Combined Value of US Homes to Top $25 Trillion in 2013, Zillow, the total value of housing stock in the five large supply-restricted metropolitan areas (Boston, LA, DC, SF, NY) is $6.5 trillion. We did not conduct a thorough search for data on the price elasticity of supply that would … Continue reading
Allowing more people to move to a higher-wage higher-productivity area is also a way to increase overall productivity and earning potential in the economy. Economists Chang-Tai Hsieh and Enrico Moretti, in a working paper, estimate that these land use restrictions depress annual output by more than $2 trillion, and wages by more than $1 trillion, by restricting the movement of workers into more productive regions.[9]“Empirical results are summarized in Table 4. We begin in Panel A with an extreme counterfactual: we consider how much larger total US output would be if the nominal wage was equalized across all metro areas in 2009. Column 1 indicates that equalizing nominal wages would increase US GDP by 17.2% … Continue reading In their model, a large majority of the foregone production is attributed to land use restrictions in New York, Washington, DC, Boston, San Francisco / San Jose, and Seattle. However, we regard this model as offering a conceptual upper bound on the gains to liberalizing land use restrictions, rather than a best guess, since its assumptions would require the majority of the US labor force to relocate to the few most productive regions for the gains to be realized.
What are possible interventions?
What policy changes could be helpful?
There are likely many types of policy changes that could reduce the harm caused by excessively restrictive local land use regulations. A few that have been mentioned to us include:
- Local governments in high-wage high-regulation metropolitan areas could simply “upzone,” permitting more and denser development.
- Local governments could change the process by which they decide how to regulate land use. For example, they could adopt a “zoning budget” targeting an overall level of housing growth, so that restrictions in one area would have to be balanced by expansions elsewhere.[10]“Professor Schleicher proposed several political mechanisms to improve the effectiveness of the zoning process: Municipal governments, rather than housing developers, could offer financial compensation to people adversely affected by new development, out of tax revenues from new development. The … Continue reading This would help align incentives of advocates for individual projects to support greater overall growth.
- Decision-making in land use policy could be re-assigned from local to regional or state authorities, which would likely be less susceptible to neighborhood pressure to oppose new development.[11]State legislatures are less subject to the extremely local pressure that often drives restrictive land use regulation:GiveWell’s non-verbatim summary of a conversation with David Schleicher, May 15, 2014: “Influencing policyIt may be effective to create an organization to draft pro-development … Continue reading
We don’t have a strong sense of which of these policies might be most helpful in addressing the problem.
Where can additional funding make a difference?
This cause seems not to have generated a lot of activity relative to our sense of its promise, which makes funding opportunities difficult to assess. Amongst other possibilities, a funder might be able to:
- Support existing local groups or seed new groups in key housing markets.[12] “Another strategy is to fund community organizers to create coalitions to changing zoning laws in cities. This type of strategy has previously been used for housing issues.” GiveWell’s non-verbatim summary of a conversation with David Schleicher, May 15, 2014
- Fund a campaign to move land use decision-making power from the local to the regional or state level. We are not aware of any existing arrangements of this form in the United States, or of any active efforts to promote them, so this would likely be an exercise in “active funding.”[13] See our blog post on passive and active funding for a discussion of this distinction.
- Support the development of a policy consensus (for example, by convening conferences or sponsoring work on this issue in prominent think tanks).[14]GiveWell’s non-verbatim summary of a conversation with David Schleicher, May 15, 2014: “Funding basic research on the effects of land use policy would be very important. There are some academic research centers that would do this, such as the Taubman Center and New York University’s Furman … Continue reading This would have the benefits of both encouraging coordination on this issue by policymakers, and improving our understanding of what policy changes are most likely to be beneficial.[15]“Research questions on the effects of land use policyFunding basic research on the effects of land use policy would be very important. There are some academic research centers that would do this, such as the Taubman Center and New York University’s Furman Center for Real Estate and Urban … Continue reading
We don’t have a strong sense of which of these funding approaches might be most promising overall.
How likely is additional funding to make a difference?
We suspect that land use reform is unusually tractable for an issue of its importance, because:
- The opposition to land use reform does not seem organized on any more than an ad hoc, local level, though it can be extremely strong at that level.[16]GiveWell’s non-verbatim summary of a conversation with David Schleicher, May 15, 2014: “The creation of a zoning law involves a large number of people, each of whom has different preferences on which developments should occur. Given this set of preferences, there can be many different outcomes … Continue reading
- Support for land use reform seems to cut across partisan boundaries.[17]Thinkers and writers from the both left (Larry Summers, Matt Yglesias) and right (Ed Glaeser and Joseph Gyourko, Reihan Salam) have written in support of reform:Summers 2014: “Probably the two most important steps that public policy can take with respect to wealth inequality are the strengthening … Continue reading
- Some economists think that most of the harm caused by land use restrictions comes from a few very expensive metropolitan areas.[18]According to research by economists Glaeser, Gyourko, and Saks, the “zoning tax” is mainly high in Boston, Los Angeles, New York, the San Francisco Bay area, and Washington, DC. Estimates for other major metropolitan areas are much smaller. Glaeser et al. 2005 Pg 359, Table 4According to … Continue reading If the need for reform is concentrated in a few key metropolitan areas, an advocacy effort with far less than universal coverage may achieve most of the potential benefits.
- There are several interest groups that are potential allies on this issue. Groups that directly participate in development – e.g. real estate developers and construction workers – may benefit financially from laws that permit denser cities. Public employee unions may also benefit from increased municipal revenues in growing cities.[19]“Public employee unions have some incentives to support population growth in cities, just as exporters support free trade. A higher population in a city means that there are more public services to provide, so more public employees are hired. It also means greater tax revenue, so public service … Continue reading Since land use reform would lower housing prices by increasing supply, in principle it ought to appeal to affordable housing advocates, though in practice the situation is complex; environmental advocacy groups appear to have a similarly ambiguous position.[20]“There has been disagreement within environmental organizations over whether to support increased urban density. Environmentalist organizations have traditionally been opposed to increasing density, due to local effects such as the removal of trees. Others believe that increased urban density … Continue reading
On the other hand, changing local policy may be difficult if land use restrictions are an economically rational response to the incentive by homeowners to protect the value of their investments.[21]Saiz 2010 argues that geographic barriers to development in some major metropolitan areas increase prices, which in turn increases the incentive to homeowners to favor laws that protect the values of their homes:“I process satellite-generated data on terrain elevation and presence of water … Continue reading
Who else is working on this?
Some major foundations support work around affordable housing, but we have not found a large campaign specifically around relaxing regulations to increase housing supply (see footnote for details).[22]The Ford Foundation has a Metropolitan Opportunity program that primarily focuses on affordable housing, transit-oriented development and smart growth, which gave out about $31 million in grants in 2014. Roughly $9M has gone to a strategy around “land use innovation” that includes a number of … Continue reading Some local organizations are supportive of, and in a few cases directly advocate for, permitting increased and denser development. Generally, these organizations are quite small.[23]GiveWell’s non-verbatim summary of a conversation with Stephen Smith, March 13, 2014: “Advocacy and research organizations Mr. Smith believes that public interest in effective zoning, land use, city planning, and transit is growing, but that it is very difficult to pinpoint organizations that … Continue reading
Questions for further investigation
Our research in this area has been relatively limited, and many important questions remain unanswered by our investigation. Further research on this cause might address:
- How much room is there for national research or advocacy on this topic, given that actual progress on this issue is likely to be local or regional?
- How feasible is it to support new groups in an area when there does not appear to be an existing organized effort to support?
- What other interest groups could be most effectively mobilized in support of reform on this issue?
- How likely are advocacy efforts to overcome existing opposition? How powerful are the contravening forces?
Our process
We decided to investigate this area because there appears to be an expert consensus that land use restrictions cause substantial economic harm, but little advocacy relative to its importance. The work of journalists such as Matthew Yglesias and Ryan Avent helped bring the issue to our attention.
We’ve spoken to roughly a dozen individuals in our exploration of this issue to date. Public notes are available from our conversations with:
