This paper considers the second-best policy problem that arises when auto travel is priced below its marginal cost and there is a substitute mass transit mode. Using analytical methods, a global comparison is made between the second-best levels of transit service and the fare and their first-best levels. The fact that the results are global permits an application to road pricing not possible with the local results of Kraus (2003).
