Air Pollution and Sick Leaves: Evidence from Social Security Data
Manheimm University, Professor of Quantitative Economicsco-editor of the Journal of the Association of Environmental and Resource Economists
We estimate the causal impact of air pollution on the incidence of sick leaves in a representative panel of employees affiliated to the Spanish social security system. Using more than 100 million worker-by-week observations from the period 2005-2014, we estimate the relationship between the share of days an individual is on sick leave in a given week and exposure to particulate matter (PM10) at the place of residence, controlling for weather, individual effects, and a wide range of time-by-location controls. Identification derives from weekly variation in air pollution concentrations within municipalities. We find that particulate matter increases sick leaves in a statistically and economically significant fashion. We also explore the heterogeneity of this effect with respect to various worker and job characteristics.
