From Workplace to Residence: The Spillover Effects of Minimum Wage Policies on Local Housing Markets

Abstract

The recent rise of sub-national minimum wage (MW) policies in the US has resulted in significant dispersion of MW levels within metropolitan areas. In this paper, we study the effect of MW changes on local housing rental markets exploiting the placed-based nature of MW policies. For each location we define both the log MW where the average resident works (the “workplace MW”) and the log MW in the location itself (the “residence MW”). We derive a partial-equilibrium model of a housing market in which MW levels in each location affect housing demand by changing the income of commuters and the prices of non-tradable consumption. The model shows that the workplace MW has a positive effect on rents whereas the residence MW has a negative effect. We construct a ZIP code by month panel using rents data from Zillow, and use a difference-in-differences design to estimate the effect of residence and workplace MW changes on median housing rents. Our baseline results imply that a 10 percent increase in the workplace MW and no change in the residence MW will increase rents by 0.69 percent (SE=0.29). If the residence MW also increases by 10 percent, then rents will increase by 0.47 percent (SE=0.16). We use our results to study the incidence of two counterfactual MW policies: a federal MW increase and a city MW increase. We estimate that landlords pocket 9.2 and 11.0 cents for every dollar increase in worker income in areas affected by these policies. However, the incidence varies systematically across space.
