Abstract: The aim of this study is to analyze the scale and cost inefficiencies in operation for the Swiss regional bus companies. For this purpose,we have considered estimation of a stochastic and a deterministic frontier cost model for a sample of 93 bus companies in 1989. The estimates of inefficiency from the frontier models are compared and discussed within the political and regulatory setting within which the Swiss regional bus companies operate. The empirical results indicate that regulation does not seem to influence the cost efficiency significantly. Only the tariff subsidies have a negative influence on efficiency. This is an interesting result because in the current transport policy debate, the abolition of this kind of subsidy has been raised.
