This paper explores the relationship between aggregate and relative congestion, returns to scale and economic growth. Aggregate congestion reduces the effective productivity of capital; relative congestion reduces the effective productivity of labour. Both forms of congestion adversely affect...

This paper reviews literature on the optimal design of pricing policies to reduce urban automobile congestion. The implications of a range of complicating factors are considered; these include traffic bottlenecks, constraints on which roads and freeway lanes in the road network can be priced,...

A growing number of roads are currently financed by the private sector via Build-Operate-and -Transfer (BOT) schemes. When the franchised road has no close substitute, the government must regulate tolls. Yet when there are many ways of getting from one point to another, regulation may be avoided...

This study examines hub-carrier scheduling and hub-airport congestion pricing using a simple hub-spoke network model incorporating both schedule delays and congestion delays. We find that in the short-middle run, where aircraft size is given exogenously, hub-airport congestion tolls are not...

The goal of this paper is to bring some unity to the theoretical side of the debate on internalization of airport congestion by showing that all the literature's theoretical results can be derived within one simple and unified framework. The analysis starts by replicating the results of...

Walters applied a demand and supply model to collect toll for easing congestion. This paper proves that his model is a lame duck, one without a supply function. It then works out a wholesome traffic and congestion model, to offer some alternative methods to solve congestion. This paper also...
