We exploit the introduction of sulfa drugs in 1937 to identify the causal impact of exposure to pneumonia in infancy on later life well-being and productivity in the United States. Using census data from 1980-2000, we find that cohorts born after the introduction of sulfa experienced increases...

Seasonal influenza is a common infectious disease that jeopardizes the health of pregnant women and may harm fetal development. I investigate the impacts of in utero exposure to seasonal influenza over the life course using nearly fifty years of flu season data in the U.S. I exploit state and...

Several strands of research document the life-cycle impacts of lead exposure during the critical period of children's development. Yet little is known about long-run effects of lead exposure during early-life on old-age mortality outcomes. This study exploits the staggered installation of water...

Several studies have demonstrated that universal helmet laws (UHLs) and other motor vehicle policies are effective in reducing fatal and non-fatal motorcycle injuries. Although state policies can improve traffic safety overall, very little is known about how they affect different segments of...

The evidence base for the study of guns and violence begins with data on such fundamental issues as the number and distribution of guns, the number of people shot each year in criminal assaults, and the frequency of gun use in self-defense. It seems that these simple descriptive statistics...

This paper proposes a test for the existence and degree of contagious presenteeism and negative externalities in sickness insurance schemes. First, we theoretically decompose moral hazard into shirking and contagious presenteeism behavior and derive testable conditions. Then, we implement the...

This paper exploits temporal and spatial variation in the implementation of US sick pay mandates to assess their labor market consequences. We use the Synthetic Control Group Method (SCGM) and the Quarterly Census of Employment and Wages (QCEW) to estimate the causal effect of mandated sick...

Using county-level data on COVID-19 mortality and infections, along with county-level information on the adoption of non-pharmaceutical interventions (NPIs) in the United States, we examine how the speed of NPI adoption affected COVID-19 mortality. Our estimates suggest that advancing the date...
