The extent to which Indian organized manufacturing performance changed after the Economic Reform of 1991 has been an important question among empirical analysts. Using input-output data from the Annual Survey of Industries for the period 1970-71 through 2007-08, this paper compares the pre- and...

An economic measure of scale efficiency is the ratio of the minimum average cost to the average cost at the actual output level of a firm. It is easily measured by the ratio of the total cost of this output under the constant and variable returns to scale assumptions. This procedure does not...

Firms within a state, states within a country, and countries across the world are continuously striving to enhance their competitiveness in the present age of globalization. This paper defines competitiveness of a production unit as the relative cost of production per unit of output. Basic...

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, which...

The input-output bundle of an efficient decision making unit (DMU) is located at a specific point on the frontier of the production possibility set. Returns to Scale (RTS) at this point can be unequivocally characterized. For an inefficient DMU, however, the input- and output-oriented...

Using the non parametric 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...

The Indian textiles industry is now at the crossroads with the phasing out of quota regime that prevailed under the Multi-Fiber Agreement (MFA) until the end of 2004. In the face of a full integration of the textiles sector in the WTO, maintaining and enhancing productive efficiency is a...

We address the problem of input aggregation in DEA models within a broader framework and provide a direct link between input aggregation in DEA on the one hand and the test of parameter restrictions implied by input aggregation in an explicitly specified production function on the other. We show...

This paper shows how one can infer the nature of local returns to scale at the input- or output-oriented efficient projection of a technically inefficient input-output bundle, when the input- and output-oriented measures of efficiency differ.

This study examines the relationship between stock market reaction to horizontal merger announcements and technical efficiency levels of the participating firms. The analysis is based on data pertaining to eighty mergers between firms in the U.S. manufacturing industry during the 1990s. We...
