Axiomatizations of the normalized Banzhaf value and the Shapley value

A cooperative game with transferable utilities– or simply a TU-game – describes a situation in which players can obtain certain payoffs by cooperation. A solution concept for these games is a function which assigns to every such a game a distribution of payoffs over the players in the game. Famous solution concepts for TU-games are the Shapley value and the Banzhaf value. Both solution concepts have been axiomatized in various ways. An important difference between these two solution concepts is the fact that the Shapley value always distributes the payoff that can be obtained by the `grand coalition' consisting of all players cooperating together while the Banzhaf value does not satisfy this property, i.e., the Banzhaf value is not efficient. In this paper we consider the normalized Banzhaf value which distributes the payoff that can be obtained by the `grand coalition' proportional to the Banzhaf values of the players. This value does not satisfy certain axioms underlying the Banzhaf value. In this paper we introduce some new axioms that characterize the normalized Banzhaf value. We also provide an axiomatization of the Shapley value using similar axioms. Received: 10 April 1996 / Accepted: 2 June 1997

A gold key to initiate a new situation in family planning work]

Because of the popularization of a responsible agricultural production system, the livilihood of peasants has been improving greatly, while the demands and needs of the general public are also increasing at the same time. Still under the influence of the traditional belief of carrying on one's family line and emphasis on having male children, married people prefer to have more childre, and the birth rate is now rising again. In order to solve this new problem, we need to teach the peasants national policies on population, land utilization, and food supply. In order to initiate a new situation in family planning work, we need to control this "gold key" of ideological education and propaganda. The emphasis should be placed on ideological education for cadres at all levels as well as the general public in order that they may understand the Party's strategy. Education on the national strategy should be combined with material interests of the peasants, and reward and punishment in production should also be linked up with that of family planning. Social measures are needed to reduce economic burdens of the peasants, offer better treatment for single-child households, and provide adequate care for old and retired people. Family planning projects should be consolidated and improved. Scientific management, facilities and techniques for birth control, compensation for working personnel in family planning, and other practical problems deserve immediate attention and solution.

由现收现付制向基金制转轨的经济学分析

文章讨论了有关养老保险体系转轨的几个基本的经济学问题。首先从宏观经济运行的角度出发探讨了以下两个问题 :为什么要从现收现付制向基金制转轨 ?对于现阶段的中国来说马上向基金制转轨是否是最优的选择 ?文章还阐释了基金制下的收益率的决定因素并对基金制与现收现付制的风险因素进行了比较 ,最后对养老保险体系的改革提出了几点建议     

基于医疗质量的公立医院绩效体系构建研究

目的：运用德尔菲法构建一套科学、可操作的公立医院绩效评价体系。方法：采用文献法研究国内外绩效评价理论,结合问卷结果形成初始量表。通过德尔菲法对指标进行两轮筛选及优化。结果：初步形成由“社会效益”、“质量安全”、“运行效益与效率”为基本结构的指标体系,包括3个一级指标、13个二级指标和72个三级指标。结论：该指标体系重点关注医院公益性及内涵质量,对公立医院绩效评价具有一定参考意义。     

双向FDI与经济增长的实证研究

从双向FDI的角度分析OFDI和IFDI与经济增长的关系。选取双向FDI对经济增长的3个主要影响因素,分别对双向FDI与GDP、投资、净出口和产业结构的关系进行实证分析。研究发现:双向FDI对于GDP和投资都具有拉动作用;IFDI对投资的影响滞后4期才能产生,对净出口的增长起到正向促进作用;OFDI的扩大不利于净出口的增长;双向FDI与三次产业都存在较强的灰色关联度。据此,提出改善对内对外投资环境、发挥双向FDI对固定资产投资和净出口的促进作用、强化双向FDI对产业结构的调整作用等建议。
