Abstract

This study examines how Economic Policy Uncertainty (EPU) shapes disparities in air pollution exposure across individuals with different levels of education. Using a shift–share instrumental variable based on world import demand to predict provincial EPU fluctuations, we construct an individual-level panel dataset linking personal exposure to EPU and SO2 concentration across six survey waves from 2000 to 2015. The results indicate that a 1% increase in the EPU index leads to an average rise of approximately 1.15μg/m3 in SO2 exposure among individuals without a high school degree, relative to those with one. Mechanism analyses suggest that this effect operates mainly through two channels:changes in government regulatory behavior and in firm-level emission decisions.
