We use data from the National Incidence-Based Reporting System (NIBRS) to examine how the probability of getting caught when committing a crime, proxied by ambient daylight, impacts criminal activity. We exploit the existence of daylight saving time (DST) to provide within-hour exogenous shock...

Optimal regulation of a polluting natural monopolist must correct for both external damages and market power to achieve a social optimum. Existing non-Bayesian regulatory methods require knowledge of the demand function, while Bayesian schemes require knowledge of the underlying cost...

We study how ambient lead exposure impacts learning in elementary school by leveraging a natural experiment where a large national automotive racing organization switched from leaded to unleaded fuel. We find increased levels and duration of exposure to lead negatively affect academic...

Using county-level Vital Statistics of the United States data from 1974-2009, we employ a differences-in-differences framework comparing influenza mortality rates in Super Bowl-participating counties to non-participants. Having a local team in the Super Bowl causes an 18% increase in influenza...

I examine the impact of prenatal total suspended particulate (TSP) exposure on educational outcomes using county-level variation in the timing and severity of the industrial recession of the early 1980s as a shock to ambient TSPs (similar to Chay and Greenstone 2003b). I then instrument for...

In 1998, a number of polluting industries, including fossil fuel power plants, were added to the list of firms publicly reporting pollution releases in the Toxics Release Inventory (TRI). This caused a large increase in reported toxic pollution, and a corresponding decrease in median housing...

We use data from the National Incidence-Based Reporting System (NIBRS) to examine how the probability of getting caught when committing a crime, proxied by ambient daylight, impacts criminal activity. We exploit the existence of daylight saving time (DST) to provide within-hour exogenous shockto...

We use a regression discontinuity design to examine students' responses to the negative incentive brought on by being placed on academic probation. Consistent with a model of introducing performance standards in which agents respond differently based on ability, we find that being placed on...
