Item Open Access Depository banks were trapped high inflation into cost inefficiency: The Turkish experience(2010) Demir, N.; Mahmud, S. F.; Babuscu, S.Turkey embraced its worst banking crisis in the year 2001 after a long history of high inflation. Only one-third of the private domestic banks could survive immediately before and then after the crisis, mainly because of cost inefficiencies. We argue that many bank managers were trapped into cost inefficiencies during the high inflation years because they over-expanded with many new branches, looking for additional costly scarce funds in order to invest in government's securities for exuberant profits. Based on a stochastic total cost frontier with inefficiency effects (CIE) model, bank samples provide strong evidence that investing more in government securities during high inflation periods is highly significant in explaning cost inefficiency differentials among banks, in contrast to low inflation periods. A policy implication is that when inflation subsides rapidly, banks which invest heavily in government securities under high inflation are confronted with financial deterioration since they cannot adjust their cost structure, e.g., by closing several of their branches, in line with revenue losses. © EuroJournals Publishing, Inc. 2010.Item Open Access The technical inefficiency effects of Turkish banks after financial liberalization(Wiley-Blackwell Publishing Ltd., 2005) Demir, N.; Mahmud, S. F.; Babuscu, S.The banking sector in Turkey has grown significantly over the last two decades of financial liberalization. One of the aims of the financial liberalization was to improve efficiency through restructuring programs including the privatization of state banks and the encouragement of mergers. In this paper we identify key factors determining the technical efficiency differentials among Turkish commercial banks in the pre-and post-liberalization periods, using the technical inefficiency effects model. We found that loan quality, size, ownership of the banks, and profitability have a positive and significant impact on the technical efficiencies of banks. The results warrant implementation of effective regulatory measures to improve the quality of the earning assets of commercial banks. Furthermore, steps by the government to encourage acquisitions or mergers for private banks and the privatization of state-owned banks seem to be consistent in improving the overall efficiency of commercial banking in Turkey.
