Abstract:
The fast expansion of ridesharing has buoyed political debates on running background checks on drivers. Though these checks protect the public by reducing contact with criminals in these services, they also eliminate an accessible income source for marginalized people, which clouds their overall effectiveness. Exploiting a ragged difference-in-difference design on monthly crime data, corroborated by our analytical prediction based on a discrete choice model, we settle the doubt on its policy effectiveness. Although we find the passage of BCL to have a negative impact on the total reported TNC-related incidents, its effect on the total number of criminal cases, especially property crimes, is surprisingly positive. Our paper highlights the importance of overall social welfare assessment beyond a specific realm in public policymaking.
