This paper asks the question, "How should the level of mass transit service be adjusted when road pricing is introduced for a substitute auto mode?" The reference point for the introduction of road pricing is second-best optimization in transit. Because this involves below- marginal-cost pricing...

This paper is concerned with the application of microeconomic theory to resource allocation in the transportation sector. The basic questions it addresses are how transportation should be priced and how capacity should be determined. Three models, the traditional highway pricing and investment...

A generalized envelope theorem is presented which has the Envelope Theorem as a special case. Relative to the Envelope Theorem, it provides greater flexibility in determining the rate of change of a value function with respect to one of its arguments. We revisit a classic result on economies of...

In recent years, a new set of models drawing on Vickrey [1969] has been developed to analyze the economics of congestible facilities. These models are structural in that they derive the cost function from consumers' time-of-use decisions and the congestion technology. Standard models, in...

There are constraints on pricing congestible facilities. First, if heterogeneous users are observationally indistinguishable, then congestion charges must be anonymous. Second, the time variation of congestion charges may be constrained. Do these constraints undermine the feasibility of marginal...
