Structural Disadvantages or X-Inefficiency? A Cost Frontier Analysis for German Co-operative Banks
Data from 764 German co-operative banks are used to estimate multi-product translog cost functions for the quartils with the lowest and the highest average costs in the sample. Based on these cost functions measures of a structural inefficiency, of X-inefficiency, and of technical and allocative inefficiencies are calculated. The results point to the considerable extent of cost inefficiency in general and of technical inefficiency in particular. Given that economies of scale and scope turn out to be rather small, cost management seems to be more important for reducing costs than the merger and acquisition activities observed so frequently in this segment of German banking during recent years.
