Price uncertainty and output concentration

This paper conducts an empirical investigation to assess the impact of price uncertainty on industry output concentration. Results show that greater price uncertainty leads to greater output concentration; the result is robust to controls for technological factors, barriers to entry effects and other industry controls. The empirical results are consistent with theory which shows that depending on firms attitudes towards risk, output concentration is likely to be endogenous to price uncertainty. Our empirical finding suggests that examining the magnitude of uncertainty could be a useful additional criteria in antitrust policymaking.     

Decentralized environmental regulations and plant‐level productivity

Using the framework provided by the Porter hypothesis, we study the impact of environmental regulations and enforcement policies on plant‐level green total factor productivity (TFP) growth and its components related to efficiency change and technical change. The detailed microdata we use are from Sweden and for the pulp and paper industry. This industry is the source of significant amounts of water and air pollution and is one of the most heavily environmentally regulated manufacturing industries. Sweden has a unique decentralized regulatory structure where the manufacturing plants have to comply with plant‐specific regulatory standards stipulated at the national level, as well as decentralized local supervision and enforcement. Our empirical results point to beneficial impacts of the environmental policies on plants' green TFP growth and sustainable production practices. We also find that political economy considerations are important, as the presence of the Green Party and aspects like plant size (with corresponding local and regional economic effects) matter in enforcement of the standards.     

Intertemporal coordination in two-period markets

This paper studies the stability of the intertemporal coordination dynamics when the common knowledge of individual expectations of future prices is perturbed in a neighborhood of a perfect foresight equilibrium. The main forces that affect stability are: (i) the effect of a change in asset demand on second period spot market prices, and (ii) the effect on asset demand of a small change in second period prices. In an intertemporal market game whose interior Markov perfect equilibria correspond to perfect foresight equilibria, it is shown that though M-rationalizability implies the stability of the intertemporal dynamics, the converse is not always true.     

Buyers' and sellers' cartels on markets with indivisible goods

This paper analyzes the formation of cartels of buyers and sellers in a simple model of trade inspired by Rubinstein and Wolinsky's (1990) bargaining model. When cartels are formed only on one side of the market, there is at most one stable cartel size. When cartels are formed sequentially on the two sides of the market, there is also at most one stable cartel configuration. Under bilateral collusion, buyers and sellers form cartels of equal sizes, and the cartels formed are smaller than under unilateral collusion. Both the buyers' and sellers' cartels choose to exclude only one trader from the market. This result suggests that there are limits to bilateral collusion, and that the threat of collusion on one side of the market does not lead to increased collusion on the other side.     

Business Strategy and Firm Reorganization: Role of Changing Environmental Standards,Sustainable Business Initiatives and Global Market Conditions

My study is framed against the backdrop of increasingly stringent environmental demands on the pulp and paper industry to reduce water and air pollution, and the changing global market conditions. I first present an observation‐based analysis conducted by visiting selected paper mills in Finland, the US, Germany and Sweden. Interesting differences and similarities emerge. Some of the observed differences lie in their focus on achieving incremental efficiency gains from better management of production processes, inventories, supply‐chain, product distribution and timing of modernization investments such as information technology. In the second part of the paper I present evidence on firms' productivity paths and the heterogeneity in productivity among relatively similar firms, and selected evidence of firms' investments in specific areas and how these affected productivity. My findings have implications for organizational behavior and business strategies employed by firms to improve their performance and productivity under changing environmental standards and market conditions.

Exchange and optimality

Summary. A feasible social state is irreducible if and only if, for any non-trivial partition of individuals into two groups, there exists another feasible social state at which every individual in the first group is equally well-off and someone strictly better-off. Competitive equilibria decentralize irreducible Pareto optimal social states. Received: September 9, 1996; revised version: February 11, 1998     

A Study on Happiness and Related Factors Among Indian College Students

Happiness is considered to be one of the ultimate goals of life. This paper studies the happiness of Indian college and university students aged between 18 and 24 years. It attempts to answer whether and to what extent happiness of a student is significantly related to aspects of social life such as time spent with family, friends, being in a relationship, logging into social networking sites; academic factors such as job prospects of the chosen field of study and academic environment; and other personal factors such as health condition, over thinking or dwelling on past bad memories, addiction to tobacco/drug/alcohol. Moreover, this paper also inquires about the relationship between a student’s average happiness with her gender as well as the income class to which she belongs. It has been observed that among different aspects of social life, time spent with family and friends are significant while logging into social networking site is found out to be insignificant. Also being in a relationship is significantly but negatively related to happiness for male students. Job Prospects of the current field of study is a highly significant covariate of happiness irrespective of the gender of the student. Among different aspects of the personal situation, dwelling on past bad memories decreases happiness of both male and female students. Addiction to tobacco/alcohol is a negative covariate of female happiness. Furthermore, income and gender are seen to play an insignificant role in the happiness of Indian college and university students.

     

Debt Restructuring and Economic Recovery: Analysing the Argentine Swap

When Argentine sovereign default in December 2001 led to a collapse of the peso, the burden of dollar debt became demonstrably unsustainable. But it was not clear what restructuring was feasible, nor when. Eventually, in 2005 after a delay of more than three years, a super‐majority of creditors accepted a swap that essentially involved the ‘pesification’ of dollar liabilities. With the IMF not playing its customary role in arranging a swap, we consider whether a bilateral bargaining approach can help explain the final settlement and the delay in achieving it. We find that the swap broadly corresponds to a bargaining outcome where substantial delay occurred for both political and economic reasons. Even after political legitimacy was assured by general elections, negotiators seeking a sustainable outcome – at a time of deep recession, profound currency under‐valuation and high sovereign spreads – realised it was better to wait before settling. Other factors discussed include the definition of sustainability criteria, the effect of inter‐creditor conflict and the role of third parties in promoting ‘good faith’ bargaining. We suggest that, while these issues need further investigation, there are institutional changes that could make them less problematic.     

Retrading in market games

When agents are not price takers, they typically cannot obtain an efficient real location of resources in one round of trade. This paper presents a non-cooperative model of imperfect competition where agents can retrade allocations, consistent with Edgeworth's idea of recontracting. We show (a) there are Pareto optimal allocations, including competitive equilibrium allocations, that can be approximated arbitrarily closely when trade is myopic, i.e., when agents play a static Nash equilibrium at every round of retrading; (b) any converging sequence of allocations generated by myopic retrading can be supported along some retrade-proof subgame perfect equilibrium path when traders anticipate future rounds of trading.
