Efficiency Analysis in Islamic Banks : a Study for Malaysia and Turkey

Abstract

In this paper, a comparison of scale efficiency, efficiency changes and total factor productivity change were conducted using the set of indicators composed of balance sheet data of 22 Islamic banks. For the period of 2009-2011, data of four banks operating in Turkey and 18 banks operating in Malaysia were used. Data Envelopment Analysis is used in the study for measuring efficiency, and Malmquist Total Factor Productivity Index is used for measuring efficiency changes and total factor productivity changes. It was determined that banks in Turkey had scale efficiency averages higher than those in Malaysia in 2009, and lower than those in Malaysia in 2010 and 2011. The change in the total factor productivities of banks in the period 2010-2011, compared to the period 2009-2010, has resulted as a decrease for Turkey and an increase for the banks in Malaysia except for 3 banks.
