Highlights We exploit staggered Uber entry to estimate TNC effects in US states via DID. TNC entry is associated with an average 3% drop in vehicle registrations in US states. Evidence supports a causal interpretation but cannot definitively establish causality. TNC entry is also associated with reduced vehicle VOC emissions estimated by EPA. Results for travel, gasoline consumption, and air pollutants are inconclusive.

    Abstract We estimate the effect of on-demand ride-hailing service market entry by Transportation Network Companies (TNCs) Uber and Lyft on per-capita vehicle ownership, energy use, travel distances, and emissions in U.S. states from 2005 to 2015 using a difference-in-difference propensity score-weighted regression model. We find evidence that TNC entry appears to cause a decline in state per-capita vehicle registrations by 3%, on average (95% confidence interval: 0.7–5.5%). Our results regarding travel distances, gasoline consumption, and several air pollutants are not conclusive, but we find evidence of a negative relationship with some EPA-estimated vehicle air emissions, representing a decline of $300 million to $900 million in externalities during the analysis period. However, these air emissions data are modeled, rather than directly measured, so we are cautious about causal interpretations, and uncertainty in the effects of TNC entry on travel distances and gasoline consumption suggests potential additional externality effects that could dominate the air emissions effect.
