The banking industry has been the object of DEA analyses by a significant number of researchers and probably is the most heavily studied of all business sectors. Various DEA models have been applied in performance assessing problems, and the banks' complex production processes have further...

This paper introduces a new methodology ensuring units invariant slack selection in radial DEA models and incorporating the slacks into an overall efficiency score. The CCR and BCC models are units invariant in their radial component, but not in their slack component, thus changing the units of...

Data envelopment analysis (DEA) assigns a score to each production unit (decision making unit--DMU) considered in the analysis. Such score indicates whether the unit is efficient or not. For inefficient units, it also identifies a hypothetical unit as the target and thus suggests improvements to...

There are two key motivations for this paper: (1) the need to respond to the often observed rejections of efficiency studies' results by management as they claim that a single-perspective evaluation cannot fully reflect the operating units' multi-function nature; and (2) a detailed bank branch...

In order to investigate the interrelationship between risk and efficiency, based on the multistage data envelopment analysis (DEA) model, this paper introduces a modified measure of risk-adjusted efficiency for the insurance industry in China from 1999 to 2006. By comparing the results from the...
