We use county-level panel data on mortality to estimate the effect of fine particulate matter (PM2.5) pollution on mortality in China. Causal inference relies on changes in local pollution correlated with demand shocks from export destinations amid the 2008 global financial crisis. Combining satellite data on local emissions with regional mortality data, we find an economically and statistically significant impact of the long- term exposure to PM2.5 on cardiovascular and respiratory mortality. Mortality impacts are largest for those 65 years and older. Using the variability in particulate levels both across time and geographic space, we examine how the dose-response function changes at higher levels of pollution. We find evidence of a concave dose-response, with diminishing marginal mortality impacts of pollution at levels beyond those in developed nations.
