摘要：

This study offers one of the first causal evidence on the morbidity costs of fine particulates (PM2.5) for all age cohorts in a developing country, using individual-level healthcare spending data from the basic medical insurance program in Wuhan, China. We implement thermal inversion as an instrumental variable to address potential endogeneity in PM2.5 concentrations. Our analysis shows that PM2.5 has a significant impact on medical expenditures in both the short and long term. The instrumental variable estimate suggests that a 10 μg/m3 reduction in monthly average PM2.5 leads to a 2.79% decrease in the value of health spending and a 0.70% decline in the number of hospital visits and pharmacy purchases.The effect is more salient for males, children, and older adults. Moreover, our estimates provide a lower bound of people’s willingness-to-pay, which amounts to 51.85 Chinese yuan per capita per year for a 10 μg/m3 reduction in PM2.5.
