The E f ect of Pollution on Labor Supply: Evidence from a Natural Experiment in Mexico City Rema Hanna Harvard Kennedy School, NBER, BREAD, and IZA Paulina Oliva University of California Santa Barbara PRELIMINARY AND INCOMPLETE Abstract Moderate e f ects of pollution on health may exert an important inFuence on labor market decisions. We exploit exogenous variation in pollution due to the closure of a large re±nery in Mexico City to understand how pollution impacts labor supply. The closure led to an 8 percent decline in pollution in the surrounding neighborhoods. Controlling for week ±xed e f ects, neighborhood ±xed e f ects, and neighborhood-speci±c year trends, we ±nd that a one percent increase in sulfur dioxide results in a 0.61 percent decrease in the hours worked. The e f ects do not appear to be driven by labor demand shocks nor di f erential migration as a result of the closure in the areas located near the re±nery. 1I n t r o d u c t i o n In the global fght against climate change, developing nations have emerged as a top priority. How- ever, imposing environmental regulations can entail signifcant capital costs on business, potentially We thank Jonathan Hill, Katherine Kimble, and Sebastian Bustos for outstanding research assistance.

hindering economic growth. For developing countries that have experienced high growth due to a rise in manufacturing and exports, fears abound that increased regulation could greatly reduce their competitiveness. As a result, many developing nations have been hesitant to enter international climate change treaties or are lax about enforcing those that they have entered into. Environmental regulations, however, can also potentially provide local bene±ts in the form of reduced health care expenditures and increased worker productivity (Dessus and Connor, 2003; and Burtraw et al., 2003). 1 Despite the importance of understanding how large these potential bene±ts are, few credible studies exist due to limited data availability. The foremost papers in the literature have focused primarily on understanding the e f ects of pollution on health and mortality, particularly infant mortality (e.g. Currie and Neidell, 2005; Chay and Greenstone, 2003). A related literature tries to infer the total cost of high pollution levels from changes in property values (e.g. Chay and Greenstone, 2005; Greenstone and Gallagher, 2008).
