School reopenings, COVID-19, and employment
研究美国各县在2020-2021学年选择面对面、远程或混合教学对疫情和就业的影响，发现面对面教学增加病例和死亡，但就业未受影响。
Using a panel of United States counties, this study compares outcomes before and during the 2020-2021 school year between locations that started K-12 instruction on campus, remotely, or through a hybrid approach. Corroborating recent studies, we find comparatively larger increases of COVID-19 cases and deaths in locations using any in-person instruction. Within the same empirical framework, we present robust new evidence that employment was unaffected by this choice, even in counties with more vulnerable populations. We posit that opening schools did not improve employment due to policy uncertainty, supported by the fact that one-quarter of schools changed teaching methods mid-year.
