Measures of inefficiency in data envelopment analysis and stochastic frontier estimation
William W. Cooper,Kaoru Tone +1 more
TL;DR: In this paper, the authors discuss recent work in developing scalar measures of inefficiency which comprehend all inefficiencies, including non-zero slacks, and are readily interpretable and easily used in a wide variety of contexts.

An epsilon-based measure of efficiency in DEA
Kaoru Tone,Miki Tsutsui +1 more
TL;DR: In this paper, the authors discuss differences between Farrell and Pareto-Koopmans efficiency measures in DEA, and propose a composite method for discriminating them, and extend the method to so-called Epsilon based-measure (EBM).
A Strange Case of the Cost and Allocative Efficiency in DEA
TL;DR: In this paper, the shortcomings of the cost and allocative efficiencies as used in the DEA literature are pointed out, and a new approach to the cost efficiency evaluation is proposed.
Journal ArticleDOI
Decomposing capacity utilization in data envelopment analysis: An application to banks in India
TL;DR: Two broad empirical findings are that competition created after financial sector reforms generates high efficiency growth, and reduces excess capacity; second, the cost gap of the short-run cost from the actual cost is higher for the nationalized banks over the private banks indicating that the former banks, though old, do not reflect their learning experience in their cost minimizing behavior.
Dynamic DEA with network structure_ A slacks-based measure approach
Kaoru Tone,Miki Tsutsui +1 more
TL;DR: A dynamic DEA model involving network structure in each period within the framework of a slacks-based measure approach that can evaluate the overall efficiency over the entire observed period and dynamic change of period efficiency.
