Are Preferential Trade Agreements with Non-trade Objectives a Stumbling Block for Multilateral Liberalization?

In many preferential trade agreements (PTAs), countries exchange not only reductions in trade barriers but also cooperation in non-trade issues such as labour and environmental standards, intellectual property, etc. We provide a model of PTAs motivated by cooperation in non-trade issues and analyse its implications for global free trade and welfare. We find that such PTAs increase the cost of multilateral tariff reductions and thus cause a stumbling block to global free trade. This occurs because multilateral tariff reductions decrease the threat that can be used in PTAs and thus the surplus that can be extracted from them. By explicitly modelling the interaction between preferential and multilateral negotiations, we derive a testable prediction and provide novel econometric evidence that supports the model's key prediction. The welfare analysis shows that the current World Trade Organization rules allowing this type of PTAs may be optimal for economically large countries, thus the model can predict the rules we observe. We also analyse alternative rules that constitute a Pareto improvement.     

Work and Welfare in Economics:

Abstract . Today's conventional economics typically ignores the impact of alternative forms of work organization upon the welfare of the worker. In effect, its methodology is concerned with the welfare of the individual as a consumer, but not with the welfare of the individual as a worker. Hence, welfare conclusions of economics are subject to challenge on grounds of being incomplete. Whether the worker is alienated or achieves self-fulfillment, etc., stands in no necessary relationship to either the formal lines of enterprise ownership, political ideology or form of economic system. Questions of authority and power in work organizations and the workplace conditions affecting the worker on the job transcend them.     

A brief technology assessment of the Carbon Dioxide effect

Significant increases in atmospheric carbon dioxide are occuring as a result of fossil fuel combustion. More than a four-fold increase over preindustrial levels may occur by the year 2100. Heating of the atmosphere, changes in precipitation patterns and global storm paths, and other resulting effects are sure to cause significant social changes. This article is essentially a methodological case study demonstrating a useful but inexpensive type of technology assessment. It summarizes current research findings on “the CO₂ effect,” and presents hitherto unpublished findings that resulted from a brief but systems-oriented approach. These findings suggest that most published forecasts of phenomena associated with a CO₂ buildup may be systematically low because various positive feedback relationships are not reflected.     

THE JOINT ARRIVAL AND DEPARTURE PROCESS FOR THE M/M/l QUEUE

We consider the M/M/1-queue and derive an explicit expression for the joint distribution of the number of arrivals and the number of departures in [0, t), given the number of customers initially present. The derivation is almost purely combinatorial, it avoids the use of generating functions, and immediately yields a simple probabilistic interpretation of the result.     

The ARCO decision: Inroads into the per se rule under Section 1 of the Sherman Act

In this study, the author analyzes the 1990 U.S. Supreme Court decision inAtlantic Richfield Company vs. USA Petroleum Company approving Atlantic Richfield’s maximum pricing plan improsed on its distributors (despite the Court’s recognition that theper se rule forbade such schemes). Theper se rule had been one of the last substantial measures of effective antitrust policy administered by enforcement authorities and the courts, perhaps even more fundamental than scrutiny of proposed mergers and predatory practices. That principle has been weakened by the ARCO decision. The author addresses some of the likely consequences of the ascendancy of the Chicago School and the NeoClassical theory generally in antitrust interpretation.     

AGRICULTURAL POLICY AT THE CROSSROADS—AGAIN

American agriculture is suffering from severe structural adjustments and from its worst financial depression since landmark price and income policies were legislated more than half a century ago. As much as one-third of the $220 billion in agricultural debt is now delinquent, nonaccrual, or subject to renegotiation. Land values have fallen precipitously in the past few years. Farm foreclosures are near 1930 Depression levels. The congressional debate over programs that could determine the course of U.S. agriculture for the remainder of the century began in the summer of 1985.     

The hydroelectricity consumption and economic growth in Asian countries - evidence using an asymmetric cointegration approach

ABSTRACT

This study examines the four commonly tested hypotheses in hydroelectricity consumption – economic growth literature for 12 Asian countries. Our results from a recently developed hidden cointegration technique uncover rich and significant relationships between negative and positive components of the variables under consideration. In particular, we find evidence to support the neutrality hypothesis in five countries (Bangladesh, Indonesia, Pakistan, Philippines, and Thailand), the growth hypothesis in four countries (India, Japan, South Korea and Taiwan), and both growth and conservation hypotheses in three countries (China, Malaysia, and New Zealand). These findings suggest that appropriate economic policies should be elaborated on the basis of the country’s specific hydroelectricity consumption–growth nexus. Finally, our new evidence suggests that the lack of stable relationship between hydroelectricity consumption and economic growth documented in previous studies for some of these countries could be due to the failure to properly account for the nonlinearity property in the data.
