Abstract: This dissertation analyses the efficiency of the Turkish banking sector by comparing the benefits obtained by deposit banks and participation banks operating from deposits/participation funds and loans (interest or profit rates) using econometric models. Firstly we comparatively examine average interest rates and profit shares by deposit banks and Islamic banks, respectively, using monthly data for the period January 2005-December 2015 using Monte Carlo Simulation. This analysis reveals that deposit banks paid a 0.49 point higher rate of interest for deposits than the profit rates paid by Islamic banks. This difference is statistically significant at conventional significant levels. Secondly, we compare interest and profit rates for the mortgage loans of the two groups of banks for the period June 2010-December 2015 using Monte Carlo simulation. We find that conventional banks offered these loans at a rate of 0.92 points lower than Islamic banks. This difference is also statistically significant at conventional significance levels. For the same period we find that, on average, Islamic banks offered commercial loans at a significantly 0.72 basis points lower rate statistically in comparison to deposit banks. Finally, we compare these groups of banks across return on assets, return on equity and net interest/profit margin using regression analysis for the period January 2005-December 2015. This analysis employs macroeconomic indicators, liquidity indicators, operational expenses, money supply indicators, asset quality indicators as explanatory variables. We find no statistically significant difference in these measures between the two groups of banks.
