Smeed (1967) derived conditions under which it is possible for a driver to depart later and arrive earlier at a destination. In this note we replicate Smeed's argument and modify one of the postulates that under realistic traffic assumptions this phenomenon cannot occur.

A model of peak period traffic congestion analyzes the effects of capacity constraints. The model predicts the temporal distribution of traffic volumes when the demand is elastic. In response to changes in traffic conditions travellers can switch to a different mode, alternate route. The delays...

We analyze the incidence of ad valorem and unit excise taxes in an oligopolistic industry with differentiated products and price-setting (Bertrand) firms. Both taxes may be passed on to consumers by more than 100 percent, and an increase in the tax rate can increase short run firm profits (and...

This paper lays out and elaborates upon the properties of an extended Chamberlinian model with applications both in Industrial Organization and Economic Geography/ Urban Economics. The framework is used to explain the impact of some major changes over the last two centuries: reductions in...

"This paper studies how trip chaining (combining commuting and shopping or commuting and child care) affects market competition: in particular, pricing and the equilibrium number of firms as well as welfare. We use a monopolistic competition framework, where firms sell differentiated products as...

A proposal has been made to build a new tunnel under the Scheldt river near the centre of Antwerp in order to relieve traffic congestion on the ring road and in an existing tunnel. The new tunnel is expected to cost more than €1 billion, and tolls have been suggested to help finance...

Thie paper proves the existence of a symmetric equilibrium with multiproduct firms using a nested logit model of demand. The demand model is parametrized by two variable which characterize different dimensions of preference variety. These reflect intragroup heterogeneity and intergropu...

Two types of location equilibria are compared. The first one is that of a simultaneous price and location game, the second is that of a two-stage location-then-price game. It is suggested that equilibrium locations are further apart under the second and profits are higher, since firms...

This article introduces the contributions of this special issue on modelling of urban road pricing and its implementation. The issue focuses on the design of urban road pricing schemes, and their spatial and temporal impacts, using quantitative transport (and land use) models. The policy...
