Air Pollution and Sick Leaves: evidence from social security data

  • Date: November, 20th. At 12,00
  • Room: 23.103 (UPF- Barcelona, Ciutadella Campus, Mercè Rodoreda Building)


Abstract: We estimate the causal impact of air pollution on the incidence of sick leaves in a representative panel of 440,000 employees affiliated to the Spanish social security system. Using more than half a billion worker-by-day observations from the years 2005 to 2014, our econometric approach fits a linear probability model for the event that an individual takes a sick leave on a given day. The model relates this decision to air quality at the place of residence, controlling for weather, individual effects, and a range of time-by-location effects. Identification derives from day-to-day variation in air pollution concentrations as well as quasi-experimental variation in PM10 that is due to Sahara dust advection, which is used as an instrument for local PM10 concentrations. We find that particulate matter increases sick leaves in a statistically and economically significant fashion. We explore the heterogeneity of this effect with respect to various worker and job characteristics.
