Uber and Traffic Fatalities by Alex Tabarrok Marginal Revolution December 31, 2023 at 7:13 am Abstract: Previous studies of the effect of ridesharing on traffic fatalities have yielded inconsistent, often contradictory conclusions. In this paper we revisit this question using proprietary data from Uber measuring monthly rideshare activity at the Census tract level. Using these more detailed data, we find a consistent negative effect of ridesharing on traffic fatalities. Impacts concentrate during nights and weekends and are robust across a range of alternative specifications. Overall, our results imply that ridesharing has decreased U.S. traffic fatalities by 5.4% in areas where it operates. Based on conventional estimates of the value of statistical life the annual life-saving benefits are $6.8 billion. Back-of-the-envelope calculations suggest that these benefits are of similar magnitude to producer surplus captured by Uber shareholders or consumer surplus captured by Uber riders. The authors, Michael Anderson and Lucas Davis, note that alcohol involvement is reported in approximately 30% of fatal crashes, which is an amazingly high number unless you think a lot of people are driving drunk. I am reminded of a clever paper by Levitt and Porter who use the proportion of crashes involving two drunk drivers to estimate that it is not that lots of people are driving drunk but rather that “drivers with alcohol in their blood are seven times more likely to cause a fatal crash” and “legally drunk drivers pose a risk 13 times greater than sober drivers.” Thus, substituting a sober driver for a drunk driver is a very good thing and so it’s plausible to me that Uber significantly reduces traffic fatalities. Consider this a public service announcement. Uber and Traffic Fatalities - Marginal REVOLUTION
