The Effect of Compulsory Schooling on Vaccination Against COVID
利用德国60岁以上人群数据，发现义务教育年限增加一年与疫苗接种率提高0.7个百分点相关，但工具变量估计显示因果效应为零。
We study the effect of education on vaccination against COVID in Germany in a sample of individuals above the age of 60. In ordinary least squares regressions, we find that, in this age group, one more year of education goes along with a 0.7 percentage point increase in the likelihood to get a COVID vaccination. In two stage least squares regressions where changes in compulsory schooling laws are used as exogenous variation for education, the effect of an additional year of education is estimated to be zero. The results hold for the compliers to the policy change which are older individuals at the lowest margin of education.
