The Norwegian public transport market has experienced a significant development over the last decade. To test hypotheses about factors affecting cost at company and county levels, we have collected accounting and production data for all the companies for the period 1986-96 from Statistics Norway. This pooled time series-cross section data set is used to estimate the effect of contractual form, economies of scale and scope, subsidy levels on cost pr vehicle km, controlling for factors as passenger density, route speed and urban areas. The same data and variables are applied to test hypotheses of market efficiency measured by cost pr passenger km. |
