International Spillover Effects of Air Pollution: Evidence from Mortality and Health Data
研究利用跨国颗粒物轨迹数据和个体死亡及急诊记录，发现中国空气污染显著增加韩国死亡率和发病率，并评估了中国环境法规的溢出效益。
Abstract International transboundary air pollution poses a significant threat to the global economy and health, yet conventional economic analyses seldom incorporate this phenomenon. By integrating transboundary particle trajectory data with individual-level mortality and emergency department visit records, we find that air pollution from China significantly increases mortality and morbidity in South Korea. We evaluate the spillover benefits of recent Chinese environmental regulations and find that a country's environmental policies could generate substantial hidden benefits for neighboring countries. Finally, we demonstrate that China's potentially strategic reductions in pollution could have undermined these benefits, highlighting the implications for additional gains through Coasian bargaining.
