This paper uses the 1918 influenza pandemic as a natural experiment to examine whether air pollution affects susceptibility to infectious disease. The empirical analysis combines the sharp timing of the pandemic with large cross-city differences in baseline pollution measures based on coal-fired...

We examine the impact of the Americanization of names on the labor market outcomes of migrants. We construct a novel longitudinal data set of naturalization records in which we track a complete sample of migrants who naturalize by 1930. We find that migrants who Americanized their names...

Air pollution was severe in many urban areas of the United States in the first half of the twentieth century, in part due to the burning of bituminous coal for heat. We estimate the effects of this bituminous coal consumption on mortality rates in the U.S. during the mid-20th century. Coal...

While a growing literature has shown that empowering women leads to increased short-term investments in children, little is known about its long-term effects. We investigate the effect of women's political empowerment on children's human capital accumulation by exploiting plausibly exogenous...
