Does the Likely Demographics of Affordable Housing Justify NIMBYism?

Abstract

NIMBYism (not in my backyard) decreases the amount of affordable housing construction. A possible motivator for this is an existing homeowner’s fear that proximity to affordable housing depresses property value. Using a hedonic regression analysis of the sales prices of homes in Sacramento County, California, this study finds that increases in the demographic characteristics in a census tract that are likely to increase if more affordable housing is built there lower the sales price of a home. This finding holds even after controlling for the percentages of racial/ethnic groups more likely to face discrimination. Policymakers should recognize this economic element of NIMBYism as they consider instruments to increase the amount of affordable housing built. We conclude with a suggestion for a knowingly controversial policy mechanism based upon cap and trade with the hope it will spur further debate on this issue.
