Local Industrial Shocks and Infant Mortality
利用非洲大型金矿开采的准实验扩张，发现地方工业发展使婴儿死亡率下降超过50%，表明尽管存在污染风险，工业发展仍是降低发展中国家婴儿死亡率的有效工具。
Local industrial development has the potential to improve health and well-being, while also damaging health through exposure to harmful pollution. It is an empirical question which of these effects dominate. Exploiting the quasi-experimental expansion of African large-scale gold mining, I find that local infant mortality rates decrease by more than 50% alongside rapid economic growth. The instantaneous reduction is comparable to overall gains in infant survival rates in the study countries from 1970 to today. The results are robust to migration. Local industrial development – despite risk of pollution – may be an effective tool to reduce infant mortality in developing countries.
