Resumen
Banking industry worldwide has been transformed due to globalization, financial liberalization, technological developments, government policies, deregulation of financial services, financial crises and increase in mergers and acquisitions since 1980. With these changes, there is a trend towards decrease in the number of banks and increase in banking concentration. Increase in banking concentration might affect competition conditions in banking industry. The decrease in the number of banks and the increase in banking concentration dominate the Turkish banking industry after the banking crises in 2000 and 2001. This paper examines the relationship between concentration and competition in Turkish banking industry. I measure the size of banking concentration by concentration ratios and Herfindahl-Hirschman index with the data of commercial deposit banks in Turkey from 2000 to 2012. Competition degree is measured by using Panzar Rosse model. The results of the study suggest that there is no permanent relation between banking concentration and competition in Turkish banks.
