Observational analysis reveals no significant impact of ride-hailing on public transportation or traffic congestion in Vancouver, suggesting complex interactions.
We investigate the long‐run effect of ride‐hailing on public transit ridership, traffic congestion, and traffic fatalities. We estimate the long‐run effect by exploiting British Columbia's use of a pre‐existing regulation in 2013 to ban ride‐hailing from Vancouver. Using difference‐in‐differences, we show that the estimated effects are sensitive to the choice of control group. Motivated by this, we use the synthetic control method to construct a counterfactual Vancouver. We do not find a statistically significant effect of ride‐hailing on our outcomes. To help understand these findings, we conduct a meta‐analysis. We find significant heterogeneity in the literature's estimates, but the average estimate is near zero.
