| Abstract: | Structural weaknesses and recent crises increased the fragility of the Turkish banking system. Consequently, 25% of the domestic commercial banks were taken by SDIF between 1997 and 2001. This study assesses the technical efficiency of nonpublic commercial banks between 1990 and 2001 following the DEA model. The study reports a declining trend in the number of efficient banks and the mean efficiency of bank subgroups. It analyzes sensitivity to the output variables and depicts consistency between the model proposals and supervisory agent decisions. Thus the DEA model can be a tool to detect and improve the sources of inefficiency by bank management and supervisory agents. (JEL G15, G21, G28) |
