| Abstract: | The paper estimates empirically cost efficiency of the Greek banking system for the period 1993–1998. The beginning of the examination period coincides with the acceleration of liberalization and deregulation of the Greek financial system, in view of the country joining the EMU. The study uses a multi-input, multi-output technology and adopts a heteroscedastic frontier model instead of a commonly used homoscedastic one to measure cost efficiency in the banking system. The empirical results show that larger banks are less efficient than smaller ones. Also, it is found that economic performance, bank loans and investments are positive related to the cost efficiency of the Greek commercial banking sector. |
