It has been a policy proposal since long to vertically separate transport and infrastructure in Germany's railway sector. The proposal received new momentum, when selling the transport subsidiaries of Deutsche Bahn AG to the public was discussed in 2008/2009. While vertical separation is...

The freight railways sector has three attributes that have proved problematic for recent experiments with vertical separation: a) a relatively high share of network costs in total delivered service costs, b) an apparent persistence of economies of scale at the "competitive" train operations...

The setting of user prices for enterprises with large fixed costs and marginal costs below average costs - "natural monopolies" - raises important policy questions regarding both efficiency and equity. It has become well accepted among economists that, in a variety of settings, welfare may be...

We describe a pair of subadditivity tests that can be used to evaluate the technological feasibility of separating a vertically integrated network monopoly into a common infrastructure component and competing operating components. We implement the tests with a Generalized McFadden cost function...

Railways restructuring takes place under very different circumstances and with very different goals in Western Europe, Central and Eastern Europe, and Russia. Observed improvements in productivity associated with vertical access and vertical separation in Western Europe are not certain to be...

This paper explores the access charge for the use of the Italian rail infrastructure. Access problems arise when the provision of a complete service to end users requires the combination of two or more inputs, one of which is non-competitive (OECD, 2004). It is a well-known fact that excessive...

Naturally monopolistic network industries are subject to regulation of access to market and charging in order to achieve optimal use of infrastructure and avoid the abuse of monopoly power. Relatively little is known what results does such regulation generate and whether it achieves objectives....
