Abstract

This paper analyses the relationship between market power in the loan and deposit markets and efficiency in the EU15 countries over 1993-2002. Results show the existence of a positive relationship between market power and cost X-efficiency, allowing rejection of the so-called quiet life hypothesis (Berger and Hannan, 1998). The social welfare loss attributable to market power in 2002 represented 0.54% of the GDP of the EU15. Results show that the welfare gains associated with a reduction of market power are greater than the loss of bank cost efficiency, showing the importance of economic policy measures aimed at removing the barriers to outside competition.
