COVID-19 Vaccinations, Business Activity, and Firm Value
利用美国门店级数据，发现疫苗接种率每提高10%，顾客访问量增加4%至6%，并提升企业销售、盈利、扩张决策，降低违约概率，但收益因企业而异。
Abstract Using establishment-level data, we show that COVID-19 vaccinations boost business activity and firm performance in the United States. A 10-percent increase in vaccination rates results in a 4-percent to 6-percent increase in customer visits. We document the channels through which vaccinations increase store visits and the limits to the effect of vaccines on business activity. At the firm level, vaccinations increase sales and earnings, impact expansion decisions, and decrease probability of default, but the benefits vary across businesses. Vaccinations create private economic benefits to firms, shareholders, and employees, in addition to their intended public health benefits.
