Measuring cost efficiency of Turkish commercial banks : a stochastic frontier approach

Güneş, Hakan
This study examines cost efficiency of Turkish commercial banks through a stochastic frontier approach where the inefficiency effects are approximated by a set of bank-specific variables. Empirical results reveal that intermediation ratio, deposits divided by liabilities and labor per branch are the main determinants of the inefficiency of Turkish commercial banks. Moreover, it is observed that cost efficiency of all commercial banks has an upward trend until 2008 and it takes 10 quarters to recover from the effects of 2008 economic crisis. On average, medium and foreign banks appear to be the most cost efficient banks within their bank groups. Moreover, while all sub-groups have an upward trend until 2008, each group recovers from the effects of 2008 economic crisis differently. Finally, empirical results reveal further that cost efficiency of commercial banks is persistent.


Managing financial instability in emerging markets: A Keynesian perspective
Akyüz, Yılmaz (Orta Doğu Teknik Üniversitesi (Ankara, Turkey), 2008-6)
The Keynesian analysis of financial instability as developed by Hyman Minsky provides considerable insights into understanding the nature and dynamics of boom-bust cycles driven by international capital flows in emerging markets. Its main policy conclusion that financial control rather than macroeconomic policy holds the key to financial stability is equally valid. There is, however, need to develop a new approach to financial control and place greater emphasis on managing capital inflows than has hitherto ...
Analyzing the profit efficiency of the Turkish banking sector after the BRSA restructuring program in 2001: an empirical study using stochastic frontier approach between the years of 2002-2009
Hatunoğlu, Hande; Akbostancı Özkazanç, Elif; Department of Economics (2012)
This thesis analyzes the profit efficiency of the Turkish banking sector after the restructuring program by using Stochastic Frontier Approach. 28 banks are included in the analysis and the data belongs to the period 2002-2009. Profit efficiency scores of 28 banks are estimated by SFA. When the efficiency scores are analyzed according to the ownership status, profit efficiency scores of the state owned banks are found higher than other bank groups. Moreover, according to the asset size, large scale banks’ p...
Determinants of non-core liabilities in the turkish banking system
Demirölmez, Beren; Tunç, Gül İpek; Department of Economics (2017)
After the 2008 global financial crises, composition of bank liabilities has begun to draw more attention due to its important role in diagnosing financial vulnerability. According to literature, non-core liabilities are amongst the best indicators of financial crises and because of the more frequent data availability, they also provide real time signaling observation. Although there are various studies about non-core liabilities, there is only a very limited number of country specific studies. Therefore, ou...
Currency and asset substitution in Turkey
Taşdemir, Özlem; Özmen, Erdal; Department of Economics (2003)
This study investigates the determinants and effects of currency and asset substitution in Turkey using quarterly data from 1987:1 to 2002:4. The empirical results from the application of Johansen procedure to a four-variable system containing currency-asset substitution proxy (M2Y/M2)), real income, real exchange rate, and ratchet effect proxy (past peak values of the depreciation of the real exchange rate) suggest the presence of a single cointegration vector among the variables. The results further sugge...
A Stress testing framework for the Turkish banking sector: an augmented approach
Çakmak, Bahadır; Öcal, Nadir; Department of Economics (2014)
This thesis proposes a suite of models, which are a set of independent but complementary models, for conducting a macro stress test of credit risk for the Turkish banking sector. First model links financial stability to macroeconomic stability and estimates the relationship between macroeconomic variables and macrofinancial variables within a VAR framework. Second model employs static and dynamic panel data techniques to regress nonperforming loans to these macroeconomic and macrofinancial variables. With a...
