JUE Insight: Distributional Impacts of Retail Vaccine Availability
利用地理空间数据，研究了美国联邦计划将COVID-19疫苗分发至商业零售药店时，若纳入低价零售商Dollar General，将大幅缩短低收入、农村和少数族裔家庭到疫苗点的距离，这些群体疫苗接种率偏低。
We examine the potential for exploiting retailer location choice in targeting health interventions. Using geospatial data, we quantify proximity to vaccines created by a U.S. federal program distributing COVID-19 vaccines to commercial retail pharmacies. We assess the distributional impacts of a proposal to provide vaccines at Dollar General, a low-priced general merchandise retailer. Adding Dollar General to the federal program would substantially decrease the distance to vaccine sites for low-income, rural, and minority U.S. households, groups for which COVID-19 vaccine take-up has been disproportionately slow.
