Measuring Islamic banks efficiency: the case of world Islamic banking sectors

The paper investigates the efficiency of the Islamic banking sectors in the world covering 25 countries during the period of 2003-2009. The efficiency estimates of individual banks are evaluated using the non-parametric Data Envelopment Analysis (DEA) method. The empirical findings suggest that during the period of study, pure technical efficiency outweighs scale efficiency in World Islamic banking countries. We find that banks from the high income countries were the leaders by dominating the most efficiency frontier during the period of study
