Abstract

In this paper, we conduct a pan-European effciency analysis to investigate the performance of European railways with a particular focus on economies of vertical integration. We test the hypothesis that integrated railways realize economies of scope and, thus, produce railway services with a higher level of effciency. To determine whether joint or separate production is more effcient, we apply a Data Envelopment Analysis super-effciency bootstrapping model which relates the ef- ficiency for integrated production to a reference set consisting of separated firms which use a di erent production technology. We find that for a majority of European railways economies of scope exist.
