Externalities such as pollution and road congestion are jointly produced by the use of intermediate inputs by firms and the consumption of final goods by households. Remarkably, to cope with such externalities policy proposals often suggest very partial tax reforms. A pertinent example is the...

In this paper, we provide a selective survey of the recent literature that deals with transport policy competition between governments. The paper shows the potential relevance of strategic behaviour by governments in deciding on prices (taxes, tolls) and investment in infrastructure capacity....

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 --...

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...

In this paper, we take a political economy approach to study the introduction of urban congestion tolls, using a simple majority voting model. Making users pay for external congestion costs is for an economist an obvious reform, but successful introductions of externality pricing in transport...

The purpose of this paper is to study tax competition on a parallel road network when different governments have tolling authority on different links of the network. Reflecting many current situations in Europe, each link is used by both local and transit traffic, and transit has a choice of...

This paper deals with costs-benefit analysis of investment in transport infrastructure. Its contribution is twofold. Firstly, we develop a general equilibrium model to explore the impact of a small budgetary-neutral investment in transport infrastructure in a second-best setting, where other...
