In this paper, the authors present a nonparametric comparative efficiency analysis of 179 communal public transport bus companies in Germany (1990-2004). They apply both deterministic data envelopment analysis (DEA) and bootstrapping to test the robustness of our estimates and to test the hypothesis of global and individual constant returns to scale. The authors find that the average technical efficiency of German bus companies is relatively low. They observe that the industry appears to be characterized by increasing returns to scale for smaller companies. These results would imply increasing pressure on bus companies to restructure.
