The standard economic model for analysing traffic congestion incorporates a relationship between speed and traffic flow. Empirical measurements indicate a region, known as hypercongestion, in which speed increases with flow. We argue that this relationship is unsuitable as a supply curve for...

The authors explore the properties of various types of public and private pricing on a congested road network, with heterogeneous users, and allowing for elastic demand. The network allows them to model certain features of real-world significance: pricing restrictions on either complementary or...

Van Reeven (2008) argues that the Mohring effect is not relevant to the determination of transit subsidies because a profit-maximising monopolist would supply frequencies that are the same as, or greater than, those that are socially optimal. We find that his results depend on the reduction or...

We formulate an empirical model of congestion for a series of sequential expressway links where queues may form and spill back. Its purpose is to disentangle the dynamic effect that a marginal vehicle has on the distribution of travel times experienced there and on connected links. We estimate a...

We study duopolistic pricing by ports that are congestible, share the same overseas customers and have each a downstream, congestible transport network to a common hinterland. In the central set-up, local (country) governments care about local welfare only and decide on the capacity of the port...
