Data Envelopment Analysis for Performance Evaluation: A Child’s Guide

RAY, SUBHASH C.; CHEN, LEI - In: Indian Economic Review 45 (2010) 2, pp. 79-124

In this paper we offer a simple exposition of the neoclassical production theoretic foundations of Data Envelopment Analysis. The concepts of technical efficiency (both input- and output-oriented), scale efficiency, and cost efficiency are explained and the corresponding DEA models are described...

Sources of Heterogeneity in the Efficiency of Indian Pharmaceutical Firms

MAZUMDAR, MAINAK; RAJEEV, MEENAKSHI; RAY, SUBHASH C. - In: Indian Economic Review 47 (2012) 2, pp. 191-221

Using the nonparametric approach of Data Envelopment Analysis (DEA), this paper examines firm’s heterogeneity in the Indian pharmaceutical industry by measuring their input and output efficiencies for the period 1991 to 2005. The analysis establishes that even though firms have been able to...
