Wie beeinflusst das Umfeld einer Bank die Effizienz? - Eine DEA-Analyse fuer die Bayerischen Genossenschaftsbanken

Although a huge literature has analysed the efficiency of the banking sector over the last years, only recently the importance to integrate further factors in the analysis has been mentioned. This paper, employing the non-parametric DEA approach to evaluate the efficiency of the Bavarian cooperative banks, investigates the impact of the environmental conditions on the technical efficiency. The results indicate that without consideration of the environment, the technical inefficiency of the banks is overestimated and thus may lead to a wrong evaluation of the quality of the managment.
