Ride-sharing, alcohol consumption, and drunk driving

We study the effect of Uber's entry on alcohol-related behaviors across major United States' metropolitan areas by using a difference-in-differences method as an identification strategy. The results show that the introduction of Uber has a positive and significant effect on the intensive margin of alcohol consumption, measured by binge drinking. However, Uber's entry has no impact on the extensive margin of alcohol consumption, measured by the number of drinking days, or on drunk driving among adults in our sample on average. The effect of Uber on binge drinking varies across demographic groups. Our findings are robust to various tests.
