ON THE EQUIVALENCE OF COMPETITIVE TRANSPORTATION MARKETS AND CONGESTION IN SPATIAL PRICE EQUILIBRIUM MODELS

This paper discusses three versions of a spatial price equilibrium model with competitive markets for transportation services. The first version models the situation where each link in the network has its own exclusive market for transportation services. The second version models a single market for transportation services, global to the entire transportation network. The third model is a hybrid of the first two, allowing the modeler to treat some clusters of economic regions as sharing a transportation market while treating others as having purely local markets. Only competitive markets in which carriers' behavior is modeled by an upward sloping supply curve are considered. It is shown that the existence of markets for transportation services is equivalent to the existence of congestion in a spatial price equilibrium model. Suggestions are given regarding the application of these models.
