In this paper we focus on the assumption of a common efficient frontier when performing an efficiency study for the … banking sector. The fact that environmental factors that are not appropriately controlled may easily bias efficiency estimates …

A persistent paradox in stochastic frontier efficiency research is that we cannot compare the X-efficiency of firms … banking market. Empirical evidence supports the view that traditional efficiency techniques based on pooled frontier … efficiency scores tend to underestimate cost and profit efficiency levels resulting in biased cross-country comparisons. …
