Housing Regulation and Neighborhood Sorting Across the United States
(Job Market Paper)

Honorable mention for best student paper at the 2024 Urban Economics Association European meeting. Winner of the Bank of Canada Student Award.

Abstract:
In this paper, I consider the effect of minimum lot size regulation on welfare and urban structure. I show that minimal lots are the most expensive in the low-density neighborhoods of productive cities relative to others, and this can explain the sorting on income into these cities and neighborhoods. Motivated by this evidence, I construct a general equilibrium model in which households of heterogeneous incomes choose cities and neighborhoods, value affluent neighbors, and are burdened differently by regulation. A counterfactual deregulation exercise shows significant and progressive welfare gains for renting households (9% of income) that offset the losses to landowners (17% of land values). The exercise also reveals two surprising results. First, any productivity gains that occur from the expansion of productive cities is largely nullified by the out-migration of affluent households who prefer regulated neighborhoods. Second, deregulation exacerbates the costs of the neighborhood choice externality arising from the demand for affluent neighbors, but only slightly. These results suggest that the most important consequence of deregulating housing markets is increasing housing affordability. Other counterfactual exercises underscore cities’ lack of incentives to unilaterally deregulate and show a significant opportunity for improved spatial targeting.

Gentrification and Redevelopment in General Equilibrium

Abstract:
In this paper, we consider the effect of housing teardown taxes on teardown rates, the distribution of housing prices, and welfare. Using a spatial difference-in-difference design, we show that a trial teardown tax of \$15,000 implemented in two Chicago neighborhoods cut the probability of a demolition permit being issued in half. We supplement this finding with evidence that redevelopment activity in Chicago caused large increases local neighborhood income. Motivated by this evidence, we construct a general equilibrium model that features forward-looking housing developers, households who differ on income and preferences for low and high quality housing, and costly movement across neighborhoods. Developers choose when to (re)develop and how many housing units to build subject to the teardown tax. New housing is of high quality, depreciates slowly over time, and "filters" to low income households. We show that scaling the teardown tax to \$60,000 and increasing spatial coverage confers benefits to low income renters (0.5% of income), but decreases average housing quality and land values by even more. These effects take decades to materialize.
