Competition in Zoning Create More Housing?
By Kevin Lavery
Why are American housing prices so high? How have zoning laws impacted the supply of housing? Is urban sprawl the answer to American housing and environmental problems? Judge Glock joins EconTalk host Russ Roberts to discuss the case for zoning laws and property taxes, the importance of competition among local governments, and the under-reported success in housing policy of cities like Houston. Judge Glock is the director of research and a senior fellow at the Manhattan Institute and a contributing editor at City Journal.
Glock says two Cheers for zoning! He believes that poor housing affordability is not simply caused by over-restrictive zoning regulations. Those who disagree with Glock will say that unaffordable housing tends to concentrate in states like California, New York, and Massachusetts, but Glock wants people to look at where zoning has been successful as well:
However, California, New York, and Massachusetts didn’t always have such high housing prices. So, what happened? Glock says that the equalization of property taxes for school districts in the Serrano vs. Priest case in California started a trend. The problem is that with the redistributive effects of property taxes, property owners received less direct benefit from their taxes, and consequently vote to keep property taxes as low as possible, leading to underfunded schools and a disincentive to build new property developments.
This is an example of the free-rider problem- those who use public goods such as public transportation don’t pay their full cost. This leads to a decline in the availability and quality of these resources as there’s a low incentive for individuals to contribute to them. To Glock, zoning policy is a good way to increase this incentive to pay for public goods and to help offset the free rider problem.
Glock advocates for zoning policy because it encourages housing competition among local governments, as seen in areas where housing is relatively affordable, such as Nashville, Oklahoma City, and Houston. Glock believes this is because these municipalities emphasize single family housing with less restrictions, whereas California and New York emphasize multi-family housing developments, which don’t seem to affect housing affordability in a positive way.
This limitation of competition is another reason California’s housing prices have skyrocketed. Glock explains how in the 1960’s, LAFCOs (Local Agency Formation Commissions) exploded in California’s counties. These agencies are able to decide when new municipalities can be created. This of course led to rent seeking existing municipalities denying the creation of new ones. Glock believes that loosening these restrictions would make it much easier for people to grow new communities outside of those already established, hence increasing competition, and decreasing housing prices.
To counter Glock’s argument in favor of suburbanization, Roberts plays devil’s advocate and highlights urban sprawl; Glock pushes this aside with his view that urban sprawl can be a positive. Glock thinks that many of the arguments against urban sprawl are solutions searching for problems that sprawl can help ameliorate in the first place. He declares that there are in fact significant problems with urbanization, especially regarding the environmental issues typically attributed to suburbanization. Furthermore, Glock states that Americans have a preference for single family housing, so why not focus on how to make the suburbs more sustainable as opposed to seeking to eliminate sprawl?
So, why does Glock only propose two cheers? A large downside of zoning policy is the reduction in housing supply, especially if it’s too strict, as Glock believes it is in America. Glock doesn’t advocate for more zoning, he wants policymakers to examine the cases of successful zoning, and explore how those tactics can be applied to their respective constituencies.
Another drawback of modern American zoning policy is propagation of a form of bootleggers and Baptists problem. In the context of zoning, the Baptists are NIMBYs (not in my backyard), who favor zoning laws because they genuinely want to preserve the historical, aesthetic, or environmental aspects of the area they live in, whereas the bootleggers are those who could care less about the state of the neighborhood, but simply care about increasing the value of their property through decreasing local competition.
This problem relates to the question of why municipalities aren’t maximizing the value of their land. Glock’s answer is the flypaper effect, which is when municipalities receive additional funding, they don’t tend to spend it on improving public services, they tend to spend this money on special interest groups.
What are Glock’s solutions to the ubiquitous rent seeking and inefficient public spending, and poor incentives? More competition and subdivision to strengthen local governments, and restoring property taxes to internalize their benefits.
After listening to this episode, I was left with some questions in addition to that takes outlined above. We hope you’ll take a moment both to consider them, and to leave a comment sharing your thoughts.
1- How might Glock’s proposed housing solutions affect the massive racial disparities in home ownership? A topic little discussed in this podcast was the impetus for zoning laws in the first place. What impact have these laws had on de facto segregation, and economic immobility for black Americans?
2- How might increasing competition among public schools through school choice result in fixing the poor incentives that an increase in the funding of schools and local services through state dollars?
3- Another policy that Houston has had success in addressing is homelessness, a topic not discussed in the podcast. What role can homeless policy play in alleviating the housing crisis?
4- One of Glock’s reasons for why urban sprawl isn’t as bad as people tend to think is due to the American preference for living in single-family homes. As one commenter pointed out, can Glock hold this perspective along with the reality of city-living being highly expensive, partly due to a large demand for condensed living? Furthermore, Americans are increasingly choosing not to have children, making suburban housing less reasonable. How will this shift in preferences change the impacts of urban sprawl in the near future?
