Abstract

Exploiting ZIP-by-month variation, this paper examines the distributional effect of the COVID-19 pandemic on housing demand across income groups. First, we document heterogeneous demand responses to pandemic shocks. We show a large increase in demand growth rate from high-income ZIP-codes during the first six months of the pandemic. The result holds true after controlling for the housing supply effect, the state-level effect, and the county-level effect. Second, we develop within-group models testing the effects of two speculation channels. We find little evidence that the strong demand response in high-income ZIP-codes is driven by fast-growing housing prices; instead, we estimate that the ultra-low mortgage rates play an important role. With prolonged pre-pandemic and post-pandemic coverage, this paper sheds light on the implications for the evolution of wealth inequality in the United States.
