Equilibrium Particulate Exposure

We assemble global, spatially disaggregated panel data on ambient particulates, population, and economic activity, and develop a macroeconomic integrated assessment model of particulate exposure for 30 countries representing 60\% of world population. The data indicate the importance of country level factors in determining particulate exposure. Model results indicate the importance of equilibrium adjustments. For example, uncompensated oil taxes and agricultural burning restrictions may unintentionally raise exposure by shifting labor to dirtier sectors or locations. Model results also showcase the importance of country heterogeneity and fiscal management. Our results suggest that effective particulates policy requires accounting for general equilibrium responses
