Anne M. Burton was awarded Cornell’s 2020 CTECH Ph.D. Dissertation Award. She is working towards her Ph.D. in Economics with Professor John Cawley. Her dissertation title is “Do Uber and Lyft Reduce Drunk Driving Fatalities?” The project investigates whether Uber and Lyft lead to reductions in drunk driving, as measured by city-level drunk-driver-related motor vehicle fatalities and fatal crashes. She is using a difference-in-differences method that exploits the variation in the timing of Uber and Lyft entry for the 100 most populous U.S. cities. Using monthly city-level Fatality Analysis Reporting System (FARS) data for 2006 to 2016, she finds that Lyft and Uber lead to a statistically significant reduction in nighttime drunk-driver-related fatal motor vehicle incidents. This effect appears to be driven by reductions in incidents several years after the entry of Uber or Lyft into a city, consistent with a lagged adoption of this new transportation technology by riders.
