Most bank efficiency studies that use stochastic frontier analysis (SFA) employ each bank’s own implicit input price when estimating efficient frontiers. But the theoretical foundation of most studies is a cost minimisation and/ or profit maximisation problem assuming perfect input markets. At...

We analyze the stability of efficiency rankings of German universal banks between 1993 and 2004. First, we estimate traditional efficiency scores with stochastic cost and alternative profit frontier analysis. Then, we explicitly allow for different risk preferences and measure efficiency with a...

German banks experienced a merger wave throughout the 1990s. However, the success of bank mergers remains a continuous matter of debate. In this paper we suggest a taxonomy as how to evaluate post-merger performance on the basis of cost efficiency (CE). We categorise mergers a success that...

In this study, we test whether regional growth in 11 European countries depends on financial development and suggest the use of cost- and profit-efficiency estimates as quality measures for financial institutions. Contrary to the usual quantitative proxies for financial development, the quality...

Efficiency is considered a key factor when evaluating a bank's performance. Moreover, efficiency enhancement is an explicit policy objective in the Single Market Directive of the European Commission. But efficiency improvements may come at the expense of deteriorating bank profits and excessive...

The "quiet life hypothesis (QLH)" posits that banks enjoy the advantages of market power in terms of foregone revenues or cost savings. We suggest a united approach to measure competition and efficiency simultaneously to test this hypothesis. We estimate bank-specific Lerner indices as measures...
