Größenvorteile im deutschen ÖSPV – Eine empirische Analyse

In this paper we present an efficiency analysis of bus transport companies in Germany. It is focused on the calculation of scale efficiencies in order to identify possible economies of sca-le in the German bus transport market. For this purpose, we apply data envelopment analy-sis (DEA). As DEA is a determintistic method, bootstrapping procedures are applied to test for global and individual returns to scale. We find that small bus transport companies achieve economies of scale by extending their size.
