A cost function is subadditive when a single firm can produce all relevant output vectors cheaper than two or more firms. In order to do so the test developed by Evans and Heckman (1984) will be used.

Furthermore, estimating models with and without regulatory and environmental factors clearly indicates that the omission of environmental factors, such as network density, substantially changes parameter estimates and, hence, leads to biased estimation results. The objective of this paper is the comparison of the efficiency levels for a set of European rail companies in monopoly situations with respect to hypothetical duopoly situations. More specifically, the aim is to test whether the operating costs function of such companies is subadditive.
