Hypothesis testing and statistical precision in the context of nonparametric efficiency and productivity measurement have been investigated since the early 1990s. Recent contributions focus on this matter through the use of resampling methods?i.e., bootstrapping techniques. However, empirical...

During the last fifteen years the competitive conditions under which Spanish banking firms operate have become much tighter. Deregulation has affected both banks and savings banks, allowing them to expand geographically and to choose a less regulation-conditioned output mix.This paper analyzes...

This paper analyzes the dynamics of cost efficiency scores in the Spanish banking industry during the period 1985-1995 and asks how such dynamics are influenced by specialization. Efficiency has been estimated through a nonparametric approach, and a model of distributions dynamics has been...
