Second, the time variation of congestion charges may be constrained. Do these constraints undermine the feasibility of marginal...

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...
