This contribution is an attempt to make an exhaustive critical review of various possible estimation methods of scale economies in a non-parametric data envelopment analysis approach. Three types of technology structure - piecewise linear, piecewise log-linear, and FDH - are found to be adopted...

Estimation of efficiency of firms in a non-competitive market characterized by heterogeneous inputs and outputs along with their varying prices is questionable when factor-based technology sets are used in data envelopment analysis (DEA). In this scenario, a value-based technology becomes an...

Designed to provide a systematic introduction to DEA and its uses as a multifaceted tool for evaluating problems in a variety of contexts. This volume reviews the basic principles taught in the authors' successful textbook, "Data Envelopment Analysis." This package includes the book in a CD-ROM...

"Data Envelopment Analysis (DEA) has grown has grown into a powerful quantitative, analytical tool for measuring and evaluating performance. It has been successfully applied to a host of different entities engaged in a wide variety of activities in many complex, multi-layered contexts worldwide....

This paper briefly reviews the existing methods of capacity utilization in nonparametric framework from economic perspectives, and then suggests an alternative in the light of limitations therein. In the spirit of work by Coelli et al. [Coelli, T.J., Grifell-Tatje, E., Perelman, S., 2002....
