The paper analyses the strategic environmental policy choices of governments for the car market. We consider two countries that each have a small number of car producers who sell cars at home and abroad, there are cross border pollution externalities and cross border R&D externalities. Each...

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...
