Rail Costs and Capital Adjustments in a Quasi-Regulated Environment

Rail Costs and Capital Adjustments in a Quasi-Regulated Environment

This paper reports on the estimation of a cost function using pooled data for major US railroads for the period of 1974-86. Analysis is performed of short and long-run returns to scale, the extent of capital disequilibrium, and the adjustments to capital in the heavily regulated and quasi-regulated environments before and after the passage of the Staggers Act in 1980. It is found that there is considerable overcapitalisation in the rail industry and that this has persisted in spite of the Act.

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.
