FIRM SIZE AND OPERATING COSTS IN URBAN BUS TRANSPORTATION

This analysis specifies a neoclassical cost model of urban bus transportation making short-run cost a function of output, inputs, and the stock of buses. The model is used to estimate a long-run cost relationship of transport operations that are largely financed by public funds for a cross-section of urbanized areas in the United States. Use of this model indicates that there are significant economies in providing additional vehicle miles for the urbanized areas studied. The average annual mileage per bus in the sample is 32,000 miles. Although the model used in this paper is restrictive in providing essential information on the structure of technology of urban bus transportation, it is adequate for our problem, given the nature of the available data. It is time that bus cost-function studies leave the phase of estimation without theory. Future research should make use of the implications of duality theory. Future research should make use of the implications of duality theory in the estimation off urban bus--cost relationships. However, this approach requires an ideal data base with detailed expenditure information on each factor input. (Author)
