Component efficient solutions in line-graph games with applications

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.     

建立河北省农业生态安全预警机制的理论探讨

目前,河北省农业生态系统整体呈不断恶化趋势,已成为影响建立农业强省的重要问题。为此,建立生态安全预警机制是必要而紧迫的。本文依据农业生态学原理、环境库兹涅兹曲线与生态安全耦合原理建立了农业生态安全的理论基础,并从观念、技术、政府作用与公众参与以及生态产权和资金投入方面进行了障碍性因素分析,最后提出了相应的对策措施。

西部高校财务预警与财务风险防范研究

为适应高校教育大众化要求,高校进入了规模扩张阶段,而政府投入的不足,使高校负债发展成为必然选择,这无形中加大了高校办学的财务风险。本文通过分析西部高校财务风险成因,提出应建立财务预警系统,并采取相应的风险防范措施,以有效控制西部高校财务风险的发生。

Bootstrap and Pretest J-Type Non-Nested Tests for Orthogonal Regression Models: Some Monte Carlo Evidence

This paper compares the size and power of two J-type tests for weakly correlated or nearly orthogonal non-nested regression models: a bootstrap and a pretest test. The latter seems to outperform the former in terms of its size characteristics, especially when the alternative model has more non-nested regressors and the orthogonality between the two sets of regressors is severe. The bootstrap test does better in terms of power.
