Concentration vs Inequality Measures of Market Structure

This paper compares market structure in different industries using conventional additive measures and various indices of firm size inequality. It is found that levels or changes in market structure are not exactly consistent across various measures. However, as compared to additive measures, inequality indices give more consistent results, and hence can be used to examine the structure of markets in different industries. Nonetheless, since there are inconsistencies across different inequality indices, efforts should be made towards formulating a suitable criterion for selecting the most appropriate measure.

Market Concentration in Indian Manufacturing Sector: Measurement Issues

The article attempts to examine the accuracy of the conventional additive measures of market concentration by using the criteria as suggested by Ginevicius and Cirba. It is found that the GRS Index of Ginevicius and Cirba is a more accurate measure of market concentration. The Herfindahl-Hirschman Index, the most widely used measure of market concentration, deviates far from accuracy. Hence, examining market concentration on the basis of the conventional indices may result in misleading conclusions and hence guide policy formulations in wrong directions.

Payments for Environmental Services: Issues and Implications for India

Programmes on payments for environmental services aim to provide economic incentives for the conservation of natural resources. They are expected to generate a continuous flow of environmental services in the long run, along with maintaining their quality. This essay elucidates the conditions required for the successful implementation of PES schemes and considers how well they may do in the Indian context. It foresees a number of formidable challenges in the schemes producing the desired outcomes in India.

Concentration-Markup Relationship in Indian Manufacturing Sector

While the positive relationship between market concentration and price-cost margin or profitability is well documented in industrial organisation literature, the present paper makes an attempt to examine the concentration-markup relationship in Indian manufacturing sector in the post-liberalisation era using dynamic panel data model. It is observed that the traditional positive concentration-markup relationship does not hold in a dynamic context, when controlled for various structural aspects of the market, firms' strategies and policies of the government. In other words, industries with greater market concentration do not necessarily enjoy higher pcm in the long run, possibly due to entry of new firms, x-inefficiency of the incumbents and deceleration in industrial production.

Acceleration of Agricultural Growth in India: Suggestive Policy Framework

In his article 'Deceleration in Agricul- tural Growth: Technology Fatigue or Policy Fatigue?' (June 23), Narayanamoorthy has argued that the crisis in Indian agriculture is mainly due to the lack of appropriate policy rather than technology.
