Determinants of child morbidity and factors governing utilization of child health care: evidence from rural India

Prevention as well as effective treatment of respiratory infections and diarrhoea depends on several individual, household and community level factors. The objective of this article is to estimate the role played by such factors in determining the occurrence of such diseases and utilization of formal health care for children under the age of three in India. The major findings are briefly enlisted as follows. First, a woman with greater educational qualification and autonomy in terms of her power to take decisions on her own, control over household resources and complete freedom to move beyond the confines of her household exerts a significant influence on the probability of seeking care. In addition to this, formal care is more likely to be sought for children whose mothers are more exposed to the media. Programmes devised to enhance utilization of formal health care for children should be targeted to catering for the needs of the vulnerable group i.e. female child, predominantly, residing in households belonging to Scheduled Tribe. In addition to this, children belonging to Muslim households are at higher risk of contracting the diseases but there is no significant difference in their health seeking behaviour as compared to other religious groups.     

Cross-border mergers and market concentration in a vertically related industry: theory and evidence

We present a tractable model of oligopoly to identify the linkages between local competition and cross-border mergers in a vertically related industry. We show that the incentives for cross-border mergers rise with vertical integration in an industry when the premerger concentration in that industry is sufficiently high relative to the concentration in the same industry in a foreign country. We also show that the incentives for a merger between a foreign firm and a vertically integrated home firm will be higher than that for a merger between a foreign firm and a disintegrated home firm, when the premerger concentration at home is low relative to the premerger concentration in the foreign country. We then analyze a firm-level panel of 90,614 M&A observations, between 1990 and 2012, from 86 countries. Logistic regressions confirm that market concentration is an important determinant of cross-border M&A. Our results support the conjectures of our theoretical model and are consistent with recent empirical findings and theoretical predictions.     

Privatization and Strategic Mergers across Borders

We present a theoretical model to capture the role of privatization in the incentives for and implications of cross‐border horizontal mergers. Absent any merger incentives in an autarkic equilibrium, we show that a decrease in the degree of privatization will lower the incentives for diversification of international production. The incentives for diversification for any given degree of privatization will fall when the private and public firms are allowed to move sequentially rather than simultaneously. The presence of the public firm also introduces a new source of asymmetry in the incentives for cross‐border mergers: a reduction in the degree of privatization at home will dampen the potential gains from a take‐over of a home firm by a foreign firm but magnify the potential gains from a take‐over of a foreign firm by a home firm.     

A public firm in a model of spatial duopoly with price discrimination

We visit the role of privatization in the location decision of firms in an industry where no firm can produce all varieties demanded. We demonstrate that the Nash equilibrium locations are socially optimal, in the presence of a publicly owned firm, notwithstanding the degree of privatization.     

Equilibrium in behavior strategies in infinite extensive form games with imperfect information

Summary We prove the existence of equilibrium in behavior strategies for extensive form games when the game has infinite actions. The result is derived under the assumption that the behavior strategies satisfy the bounded measurability condition. The condition implies that the behavior strategies are restricted to those which can be viewed as continuous functions from the set of initial histories to the space of probability distributions over action spaces which satisfy the Lipschitz bound.I am grateful for the helpful comments of an anonymous referee.     

Import competition,employment and wage in US manufacturing: new evidence from multivariate panel cointegration analysis

This paper examines whether employment and wages in the US manufacturing sector exhibit any long-run relationship with import competition. The results based on a multivariate panel cointegration analysis of observations on 12 two-digit SIC manufacturing industries over the period from the third quarter of 1982 to the fourth quarter of 1992 indicate that US manufacturing employment does not bear a long-run relationship with import competition but manufacturing wage does. While the long-run correlation between import price and manufacturing wage is found to be sector sensitive panel estimation reveals a highly significant negative correlation between import price and manufacturing wage.     

COLLUSIVE EQUILIBRIUM IN COURNOT OLIGOPOLIES WITH UNKNOWN COSTS*

The article studies collusive equilibria in an infinitely repeated Cournot oligopoly with unknown costs. I look at collusive pooled Perfect Bayesian equilibria and separating equilibria either with signaling or with communication. In the separating equilibria with signaling the firms play the strictly separating Bayesian Nash equilibrium in period 1 and produce the optimal incentive compatible collusive quantity vector from period 2 onwards. In the separating equilibrium with communication the optimal incentive compatible quantity vector is produced from period 1 onwards. Among these, the optimal separating equilibrium with communication gives the highest expected discounted joint profits.     

Real exchange rates and real interest rates once again: a multivariate panel cointegration analysis

This paper employs multivariate panel cointegration techniques to re-examine the empirical relationship between bilateral real exchange rates and real interest rates. The results from a panel of 1470 quarterly observations on Canada, France, Germany, Italy, Japan, UK, and USA over the period 1977 to 1994 indicate the absence of any long-run relationship between the two variables.     

Trends in innovation and productivity: The case of chemical and textile industries in the U.S.

This paper attempts to investigate an empirical linkage between technological innovation and productivity in two industries in the United States. During the period 1967—82, the chemical and textile industries experienced different rates of productivity growth. In spite of stiff competition from foreign manufacturers, American textile firms maintained a steady growth in productivity. This industry benefitted from major technological innovations occurring in industries supplying to it. The chemical industry faced crisis due to sudden changes in petroleum prices. Changes in regulatory requirements also imposed a different set of constraints on the chemical industry. Rate of innovation decreased quite severely in this industry during this time period.
Innovation indicators were developed by obtaining data on new product/process announcements in the technical literature. Panels of technical experts from the industries and academia evaluated the data for their technical novelty. The data indicate a relationship between innovation and productivity growth.
