Assessing profitability factors in the Greek banking system: a multicriteria methodology

The increasing competition in the national and international banking markets, the changeover towards monetary union and the new technological innovations herald major changes in the banking environment, and challenge all banks to make timely preparations in order to enter into the new competitive monetary and financial environment. Therefore, it is interesting to investigate the effectiveness of Greek banks, as it is valued by the financial markets, i.e. the greater the efficacy the higher the competitiveness and vice versa. Taking into consideration the bank assets, we distinguish banks into small and large ones. Finding factors that make the differences in such effectiveness may explain the effective advantage of these two types of financial institutions and help us understand the ‘financial intermediation’ industry in Greece better. Based on their size, a classification of Greek banks, in a multivariate environment, according to the return and operation factors for the years 1900–1999 takes place. In order to investigate the differences of profitability and efficiency between small and large Greek banks, as well as the factors of profitability and operation related with the size of banks, a multicriteria methodology has been used. The results of this paper may help us determine the key success (or failure) factors of these two categories of Greek banks as well as the responsible banking decision-makers for future readjustments.
