In this paper we optimize the regulation of an intersection of two routes connecting one origin-destination pair and study the effects of priority rules, traffic lights and tolls. We show that when the intersection is regulated by a priority rule the optimal policy is generally to block one of...

This paper proposes an analytical formulation of discomfort in mass transit and discusses its micro-economic properties. The formula we introduce reflects real situations faced by the passengers, it has nice mathematical properties and it is easy to compute. The discomfort formulation is used to...

This paper studies the political economy of pricing and investment for excludable and congestible public goods in a federal state. Currently, we observe a wide variety of practices, ranging from federal gasoline taxes and road investment to the local supply of -- and sometimes free access to --...

The paper challenges part of the sustainable transport literature. Sustainable transport plans often focus on reducing carbon emissions in a specific city, region or country, and this neglects two handicaps of strong unilateral action. The first is that climate is a global commons problem, so a...

This paper studies the political economy of public transport pricing and quality decisions in urban areas. We consider a hypothetical two-region federation. In each region there is a demand for public transport and for car use, and the group mainly using public transport may be a majority or...

Many transport and other service problems come down to simple network choices: what mode and/or route to take, when some of the routes and modes are congested and their use can be priced or not priced by different operators. The operators can have different objectives and face different market...

This paper considers various policy measures to reduce traffic externalities in cities, including externality-reducing investments, tolls, emission standards, low emission zones, and bypass capacity to guide traffic around the city center. Using a simple model that distinguishes local and...

This paper analyzes strategic interaction between intercontinental airports, each of which levies airport charges paid by airlines and chooses its own capacity under conditions of congestion. Congestion from intercontinental flights is common across the airports since departure and arrival...

We use a simple economy with two interconnected geographical zones. Individuals can live and work in one of the two zones or can commute between them. This model is used to explore the dynamics of housing and work decisions after a permanent shock in labour demand occurred in one of the two...

This paper explores reforms of pricing of private and public transport in Paris. Paris has used a policy of very low public transport prices and no road pricing. The Paris transport network is represented as a stylized concentric city with the choice between car, rapid rail, metro and busses as...
