Potential Gains from Mergers in Local Public Transport: An Efficiency Analysis Applied to Germany
Walter, Matthias; Cullmann, Astrid - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2008
We analyze potential gains from hypothetical mergers in local public transport using the non-parametric Data Envelopment Analysis with bias corrections by means of bootstrapping. Our sample consists of 41 public transport companies from Germany's most densely populated region, North...
