This paper considers the welfare impacts of a range of franchising regimes for congestible highways. For a single road in isolation, it is shown that a competitive auction with the level of road use as the decision criterion produces the socially optimal road (in terms of capacity and toll...

This paper studies the efficiency impacts of private toll roads in initially untolled networks. The analysis allows for capacity and toll choice by private operators, and endogenizes entry and therewith the degree of competition, distinguishing and allowing for both parallel and serial...

This is also the case in Vickrey's (1969) 'bottleneck model'. To...</p></a>

This paper provides a link between car following theory and the economic theory of road congestion by means of a theory of speed choice. According to this theory speed choice is based on a trade-off between the benefits (shorter travel time) and cost (higher accident risk) of driving faster....

In this paper we argue that authorities aid cooperation by means of direct coordination or the enforcement of re-commitment devices such as contract laws.Credible threats of violence allow this role. In a local interaction model, an authority forms if mutually connected individuals with...

In densely-populated countries and in particular in large metropolitan areas, the presence of so much human activity causes all sorts of negative externalities, for example traffic noise disturbance. These externalities call for corrective measures by the government. Economists have developed a...
