The comparative static predictions of the Baron and Ferejohn [Baron, D.P., and Ferejohn, J.A., (1989). Bargaining in legislatures, American Political Science Review 83 (4), 1181-1206] model better organize behavior in legislative bargaining experiments than Gamson's Law. Regressions similar to those employed in field data produce results seemingly in support of Gamson's Law (even when using data generated by simulating agents who behave according to the Baron-Ferejohn model), but this is determined by the selection protocol which recognizes voting blocks in proportion to the number of votes controlled. Proposer power is not nearly as strong as predicted in the closed rule Baron and Ferejohn model, as coalition partners refuse to take the small shares given by the continuation value of the game. Discounting pushes behavior in the direction predicted by Baron and Ferejohn but has a much smaller effect than predicted. 相似文献

Summary. This paper presents a general procedure for finding profiles with the minimum number of voters required for many important
paradoxes. Borda's and Condorcet's classic examples are revisited as well as generalizations. Using Saari's procedure line,
we obtain an upper bound for the minimum number of voters needed for a profile for which the Condorcet winner is not strictly
top ranked for all weighted positional procedures. Also we give a simple upper bound on the minimum number of voters needed for a set of prescribed voting outcomes. In contrast to situations wherein small numbers of voters are needed, we consider paradoxes
requiring arbitrarily large numbers of voters as well as large numbers of alternatives. Finally we indicate connections with
statistical rank based tests.

This paper contributes to the literature on integovernmental competition in two ways. First, the institutional setting within which public services are delivered is analyzed with respect to the impact on the quality of services provided. Previous studies have measured competition only in terms of governmental structure, ignoring the issue of service quality and the potential for differentiating local governmental jurisdictions along quality dimensions. Second, the outcome of competition is defined in terms of service quality. Previous studies generally have measured the outcome of competition by examining the fiscal effects of fragmentation and accountability through service costs or tax revenue impacts. School districts were used to empirically test quality competition. Student academic performance was modeled as a function of control variables and the degree of competition from neighboring school districts. Academic performance in public schools was positively associated with the performance of neighboring districts, although the effect was small. These findings, however, suggest that strategies to strengthen interjurisdictional competition may be useful in enhancing public service quality. 相似文献

We offer a game-theoretic proof of Hamiltons rule for the spread of altruism. For a simple case of siblings, we show that the rule can be derived as the outcome of a one-shot prisoners dilemma game between siblings.JEL Classification:

Summary. An economy with two dates is considered, one state at the first date and a finite number of states at the last date. Shareholders determine production plans by voting - one share, one vote - and at
-majority stable stock market equilibria, alternative production plans are supported by at most
percent of the shareholders. It is shown that a
-majority stable stock market equilibrium exists if
where S is the number of states at the last date and J is the number of firms. Moreover, an example shows that
-majority stable stock market equilibria need not exist for smaller

以“理性人”假设为基础的传统财务决策理论将决策者独立于投资决策过程之外,认为决策者完全能够依据理性决策模型做出最优的决策,但现实并非如此。本文对行为决策理论中关于投资决策的研究文献进行了梳理,揭示了决策者的行为特征会影响到投资决策及投资回报率的设定,展望了行为决策理论在我国的发展前景及实践意义。 相似文献

It is recommended for economists to examine China’s Urban-Rural disparity from the perspective of transaction efficiency,
in that it can provide us with a systematic explanation to both the cases of different countries and development stages. China’s
Urban-Rural disparity is special and virtually a demonstration of its special transaction efficiency structure. Exploration
of China’s Urban-Rural disparity from such perspective indicates that, different from those in countries with a market economy,
China’s case involves many exogenous and contrived factors. Therefore, the solutions are to improve the whole transaction
efficiency in the economy, which includes eliminating its regionally unfavorable policies and institutions, and enforcing
more favorable and regionally balanced institutional reforms.

控制权性质影响税收敏感性吗?——基于企业劳动力需求的检验 总被引:9,自引:2,他引:9
西方学者研究表明企业所得税是劳动力需求的重要影响因素,这一理论在中国是否适用?中国大部分上市公司为国有控股企业,这一特殊的制度背景是否会影响企业所得税与劳动力需求的关系?本文基于2007年企业所得税改革这一外生政策变化,在检验西方企业所得税与劳动力需求关系的理论在中国是否适用的基础上,就不同控制权的性质是否会影响企业劳动力需求的税收敏感性进行了检验。研究发现企业所得税税率降低和"就业税盾"增加提高了企业劳动力需求,但这种税率和"就业税盾"的变化对国有控股企业劳动力需求变化的影响要显著小于非国有控股企业。这表明税收是影响企业劳动力需求的重要因素,但国有控制权使得这种税收敏感性变弱。本文的研究结果不仅丰富了相关领域的国际学术文献,而且对我国就业政策的制定具有政策含义。 相似文献

目前,我国大多数公共投资项目由政府投资建设厦经营管理,其结果是经营管理效率低下、建设资金短缺、融资难等问题日益突出,发展特许权经营已被公认为解决上述问题的有效模式。本文从法律、风险分担、政府监管等角度分析了在公共投资项目领域实施特许经营所面临的问题,并提出了有效实施特许经营模式的对策与建议。 相似文献
