Component efficient solutions in line-graph games with applications   总被引:1,自引:0,他引:1  
Recently, applications of cooperative game theory to economic allocation problems have gained popularity. We investigate a class of cooperative games that generalizes some economic applications with a similar structure. These are the so-called line-graph games being cooperative TU-games in which the players are linearly ordered. Examples of situations that can be modeled like this are sequencing situations and water distribution problems. We define four properties with respect to deleting edges that each selects a unique component efficient solution on the class of line-graph games. We interpret these solutions and properties in terms of dividend distributions, and apply them to economic situations. This research has been done while the third author was visiting Tinbergen Institute at the Free University, Amsterdam. The research is part of the Research Programme “Strategic and Cooperative Decision Making” at the Department of Econometrics. Financial support from the Netherlands Organization for Scientific Research (NWO) in the framework of the Russian-Dutch programme for scientific cooperation, is gratefully acknowledged. The third author also appreciates partial financial support from the Russian Leading Scientific Schools Fund (grant 80.2003.6) and Russian Humanitarian Scientific Fund (grant 02-02-00189a). We thank three anonymous referees for their valuable comments.  相似文献

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 It summarizes current research findings on “the CO2 effect,” and presents hitherto unpublished findings that resulted from a brief but systems-oriented approach.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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

Forecasts are developed for the diffusion of robotics in the state of New York through the year 2015. The chief objective is to compare static approaches with dynamic models for forecasting diffusion processes of various time horizons. Results for a Bass-Mansfield model are compared to those for a dynamic time-varying parameter model. The results indicate the advantages and disadvantages of a robust heuristic approach which smooths data as opposed to providing an optimal fit.  相似文献

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.  相似文献
