This chapter offers an overview of Data Envelopment Analysis as a nonparametric method of measuring efficiency in production. Special attention is devoted to alternative returns to scale assumptions about the technology and identifying the local nature of returns to scale at projections of an...

This article makes an objective assessment of the impact of economic reforms of 1991 on productivity change in Indian manufacturing at a disaggregated level of industrial classification. Using the state-level input–output quantity data constructed from Annual Survey of Industries (ASI)...

In this paper we use the nonparametric method of Data Envelopment Analysis (DEA) to obtain Pareto-Koopmans measures of technical efficiency of individual states over the years 1970–71 through 2000–01 in a multi-output, multi-input model of agricultural production. We disaggregate overall...

As a measure of overall technical inefficiency, the Directional Distance Function (DDF) introduced by Chambers, Chung, and Färe ties the potential output expansion and input contraction together through a single parameter. By duality, the DDF is related to a measure of profit inefficiency,...

This paper uses the nonparametric DEA methodology to estimate cost and profit efficiency of Indian banks during the post-reform period. The results show considerable variation in average levels of profit efficiency across various ownership categories of banks. In general, state owned banks are...
