A Non-Radial Measure of Efficiency in Indian Textile Industry: An Analysis of Unit-Level Data

In this paper we apply Data Envelopment Analysis (DEA) to firm level data from various years of Annual Survey of Industry to obtain Pareto-Koopmans measures of technical efficiency in the Indian textile garments industry. The overall efficiency measure is multiplicatively decomposed into an input- and an output-oriented Russell type non-radial measure. For the second stage regression of DEA efficiency scores in terms of age, ownership, regional location, and other characteristics of a firm, we perform a Box-Cox transformation of the one-sided dependent variable to avoid using a Tobit regression in a context where there is no obvious censoring of the data.
