The primary goals are to summarize and critically review empirical estimates of financial institution efficiency and to attempt to arrive at a consensus view. We find that the various efficiency methods do not necessarily yield consistent results and attempts to remedy these situations by specifying more globally flexible functional forms in the parametric approaches and trying to implement stochastic versions of the nonparametric approaches should continue. In terms of applications, research on financial institution efficiency has largely focused on using institution efficiency estimates to inform government policy (e.g., by assessing the effects of deregulation, mergers, and market structure on industry efficiency) and improve managerial performance. Then the paper suggests some new directions for future research. Most of the important suggestions concern finding explanations of efficiency that may help inform government policy, identify the economic conditions that create inefficiency, and improve managerial performance.
