Economies of Scale in Bus transport: I. Some British Municipal Results

This study was prompted by the proposal to merge a number of municipal transport undertakings into Passenger transport Authorities. The authors analyse figures showing various working expenses per bus-mile, and find no evidence of scale economies. They point out, however, that the P.T.A.s will be larger than any undertaking in their sample, and that a different conclusion might conceivably be reached if data were available on costs per passenger-mile. Extension of one-man operation appears to offer greater scope for economies than amalgamation.

An Analysis of Fortress Hubs in Airline Networks

This paper explores the possibility that the fortress hub is a consequence of the nature of airline hub-spoke rivalry. Entry into a competitor’s local market may reduce the entrant’s profit in his own market. As a result, there is a deterrent to entry if the negative effects are strong enough. The paper also examines the impacts of local competition on consumer surplus and total social surplus.

Optimal Pricing of Urban Passenger transport: A Simulation Exercise for Belgium

First, a simple theoretical model is developed that determines optimal prices for private and urban transport services in both the peak and off-peak periods of the day, taking into account all relevant private and external costs. Second, the model is implemented to study pricing policies in Belgium, using recent estimates of private and social marginal costs. Several applications are then considered.

Road Casualties in London in Relation to Public transport Policy

Exceptional changes in bus and underground rail fares in London in the early 1980s prompted analyses of the effects of fare levels and petrol prices upon the numbers of road casualties in London. Earlier estimates of the number of extra casualties associated with a period of unusually high fares in the early 1980s are shown to have probably been too high.

Optimal Public transport Price and Service Frequency

Because values of time and passenger behaviour depend on the level of frequency it is found that: (1) in urban public transport there may be one low-deficit local optimum and one high-deficit local optimum, one of which is global; (2) contrary to what might be expected, optimal financial deficit per passenger is typically larger for high frequency services than for low-frequency services; (3) the optimal off-peak may exceed the optimal peak price.
