讲座内容：本文研究中国空气质量新标准如何影响空气污染在人口流动中的作用。利用2015年人口抽样调查中个体2010年至2015年的常住地信息，我们发现这个政策通过人口外流减少了污染地区的人口。而这些人口外流主要是由严格的环境规制和相伴而生的劳动力市场条件恶化导致的。通过构造人口流动和环境规制的结构化模型，我们发现环境规制的成本至少相当于空气质量优化带来的收益的14%。同时，本文也在理论上证明环境规制可能普遍影响学者们利用迁移选择估计出的支付意愿。

Abstract：We study the impact of China's air quality monitoring and disclosure program on migration response to air pollution. Using information on individual residential locations in 2010--2015 from the 2015 Population Census, we find that this program caused a larger population drop in prefectures with poorer air quality by pushing residents away. These outflows mainly stemmed from worse labor market conditions after stringent measures for pollution crackdowns. The economic costs were greater than 14% of the gains from air improvement. We also show that regulation can universally generate a downward bias in estimating individuals' willingness to pay for clean air.
