Abstract:

We study the economics of information provided by navigation apps that guide users through local roads. We examine the app’s incentives to provide users with information that reduces their travel cost, either by taking local shortcuts (rat runs) or by accounting for traffic calming policies by local governments. We establish that, under reasonable conditions, the information provided by the app enables excessive shortcuts. These conditions depend on marginal external costs of congestion, on externalities on the local population and on other traffic management policies (e.g., road tolls). However, we also show that the app may have insufficient incentives to incorporate traffic calming information in its paths. We also examine the response by local governments when designing their traffic policy.
