Environmental Regulations, Air and Water Pollution, and Infant Mortality in India
利用印度空气和水污染及环境法规的独特数据集，采用双重差分法评估法规效果，发现空气法规显著改善空气质量但婴儿死亡率下降不显著，水法规无显著效益，并指出公众支持是法规有效执行的关键。
Using the most comprehensive developing country dataset ever compiled on air and water pollution and environmental regulations, the paper assesses India's environmental regulations with a difference-in-differences design. The air pollution regulations are associated with substantial improvements in air quality. The most successful air regulation resulted in a modest but statistically insignificant decline in infant mortality. In contrast, the water regulations had no measurable benefits. The available evidence leads us to cautiously conclude that higher demand for air quality prompted the effective enforcement of air pollution regulations, indicating that strong public support allows environmental regulations to succeed in weak institutional settings.
