The Long-term Impact of Preventative Public Health Programs
研究美国1908-1933年县级卫生部门对儿童的预防性健康服务，发现5岁前接触该项目的男性成年后收入提高2%至5%，且比未接触的兄弟收入更高。
Abstract This paper estimates the long-term impact of childhood exposure to a preventative public health programme on adult human capital. From 1908 to 1933, local governments in the United States instituted county-level health departments (CHDs) that provided preventative health services geared towards children. This paper estimates the long-term benefits of childhood exposure to this public programme using variation in CHD location, timing and age of exposure. CHD operation before the age of 5 increases men’s later-life earnings by 2% to 5%. Exposed boys not only perform better than later- and never-treated groups, but, after adding household fixed effects, exposed men earn more than their brothers.
