This paper employs stochastic frontier cost and profit models to estimate economies of scale as well as X-efficiency for multi-billion dollar European and U.S. banks in the period 1995-1999. Empirical results with respect to separate analyses of large European and U.S. banks are strikingly...

In this paper, I investigate whether improving the traditional SCP model gives additional insights in the existence of market power in the Dutch banking market. I first improve the measurement of market structure. Then, I introduce a simple Cournot-model, which results in a more flexible measure...

A persistent paradox in stochastic frontier efficiency research is that we cannot compare the X-efficiency of firms without assuming these firms to operate under a common frontier. In this paper, we address this imbalance by constructing so-called metafrontiers. Specifically, we build on recent...
