The COVID-19 pandemic has exacerbated the housing crisis in the United States. In response, policy makers are investing heavily in rental assistance programs. In partnership with a mid-sized US city, the People Lab is conducting a randomized experiment (N = 62,729) to evaluate the effect of reducing the learning and psychological costs associated with accessing emergency rental assistance on benefit take-up, and on subsequent eviction rates. The intervention leverages insights from behavioral science to deliver information about an emergency rental assistance program through a single mail-based communication to low-income renter households. Results are expected in Spring 2021.
