The Impact of Indonesian Forest Fires on Singaporean Pollution and Health
利用卫星火点数据作为工具变量，首次因果识别了印尼森林火灾产生的跨境烟雾对新加坡诊所就诊量的影响，发现火灾辐射功率每增加一个标准差，新加坡污染上升1.4个标准差，呼吸道感染和结膜炎就诊量各增加0.7个标准差。
Forest burning in Indonesia results in severe episodes of “seasonal haze” in neighboring Singapore. We offer the first causal analysis of the transboundary health effects of the Indonesian forest burning. Instrumenting for air pollution with satellite fire data, we estimate the impacts of the Indonesian fires on Singaporean polyclinic attendance for acute upper respiratory tract infections and acute conjunctivitis. We find that a one standard deviation increase in the Indonesian fire radiative power increases Singaporean pollution by 1.4 standard deviations and causes a 0.7 standard deviation increase in polyclinic attendance for each of the illnesses examined in this paper.
