Do Islamic Banks Have Greater Market Power?

Posted by D. Daniel Sokol

Laurent Weill of the Laboratoire de Recherche en Gestion (LARGE) (Management Research Laboratory) Université de Strasbourg asks, Do Islamic Banks Have Greater Market Power?

ABSTRACT: The aim of this paper is to investigate whether Islamic banks have greater market power than conventional banks. Indeed Islamic banks may benefit from a captive clientele, owing to religious principles, which would be charged greater prices. To measure market power, we compute Lerner indices on a sample of banks from 17 countries in which Islamic and conventional banks coexist over the period 2000-2007. Comparison of Lerner indices shows no significant difference between Islamic banks and conventional banks. When including control variables, regression of Lerner indices even suggests that Islamic banks have a lower market power than conventional banks. A robustness check with the Rosse-Panzar model confirms that Islamic banks are not less competitive than conventional banks. The lower market power of Islamic banks can be explained by their different norms and their different incentives.
