Nash equilibrium and generalized integration for infinite normal form games

Infinite normal form games that are mathematically simple have been treated [ Harris, C.J., Stinchcombe, M.B., Zame, W.R., in press. Nearly compact and continuous normal form games: characterizations and equilibrium existence. Games Econ. Behav.]. Under study in this paper are the other infinite normal form games, a class that includes the normal forms of most extensive form games with infinite choice sets.Finitistic equilibria are the limits of approximate equilibria taken along generalized sequences of finite subsets of the strategy spaces. Points must be added to the strategy spaces to represent these limits. There are direct, nonstandard analysis, and indirect, compactification and selection, representations of these points. The compactification and selection approach was introduced [Simon, L.K., Zame, W.R., 1990. Discontinuous games and endogenous sharing rules. Econometrica 58, 861–872]. It allows for profitable deviations and introduces spurious correlation between players' choices. Finitistic equilibria are selection equilibria without these drawbacks. Selection equilibria have drawbacks, but contain a set-valued theory of integration for non-measurable functions tightly linked to, and illuminated by, the integration of correspondences.     

企业财务战略联盟研究

并购作为企业扩张的方式之一,需要大量的资金和内部协调成本,而且随着规模的扩大极易产生“大企业病“,其解决的方式是战略联盟。自20世纪80年代以来,战略联盟组织形式在西方企业界得到了迅速发展,尤其跨国公司之间在全球市场竞争中纷纷采取这种合作方式。财务战略联盟是迄今为止最先进的财务战略,是一个新的发展领域。本文分析了企业财务战略联盟的内容、优势,着重探讨了财务战略联盟的建立问题。     

关于教育券制度的经济学思考

教育券作为近年来的新兴事物，不仅在国内外，而且在哲学、经济学、社会学、法学和行政学等领域均引发了激烈的争议。从经济学角度来看，主要体现在基金性质、机会均等、市民价值、教育质量和实践难题等五个方面。尽管如此，这一制度对我国的教育发展仍然具有相当大的借鉴意义。     

基于模糊多准则群决策的可持续项目选择模型

将模糊多准则群决策方法应用于可持续项目的选择决策中。首先构建可持续项目选择框架,包括投资的经济、社会和环境影响以及战略联盟、组织准备和投资风险六个评价准则。由于该框架的准则权重很难通过一组决策者不一致的偏好而确定,所以,运用乘法偏好关系和模糊偏好关系收集决策者对准则权重的偏好,利用目标规划方法进行建模并确定各个准则的相对权重;然后用模糊TOPSIS方法评估投资机会的适合程度。TOPSIS方法是基于偏好比率的一种决策方法,其中偏好比率运用于模糊数排序和模糊距离测量,可以有效地计算出每个备选方案与理想方案的模糊距离,从而根据距离判断其亲密系数,并最终应用于最佳方案的抉择。最后,以某投资集团的可持续投资项目选择问题为例进行分析,验证了方法的有效性和可行性。     

Call it good,bad or no news? The valuation effect of debt issues

Studies investigating market reactions to changes in capital structure aim to find the impact of private information conveyed. However, these studies ignore that financial decisions are not made randomly but are conditional on managers’ private information. Using a sample of U.S. leverage‐increasing public companies with public long‐term debt offerings, we find that debt offerings convey no new information to the markets after considering the conditionality of decisions. We also show that results can be biased if the deterministic role played by private information ex ante is omitted, which may explain the conflicting valuation evidence found in the literature.     

科技评价中指标初步筛选的实证研究

为了对科技评价中的指标进行筛选,以中国科学技术信息研究所医学期刊为数据源,采用主成分分析、因子分析、灰色关联分析和逼近理想解的排序法进行评价,并将评价结果作为因变量,所有指标作为自变量进行回归,筛选出若干不相关和负相关指标,供专家在指标选取时进行参考。研究发现,如果指标选取不当,在用主成分分析、因子分析或灰色关联分析进行评价时,会出现某些指标增加但总评分值反而减小的异常现象。而本方法可以预先向专家提供翔实的分析数据,有利于提高指标选取的准确度和效率。     

中小企业技术创新法律保障的路径选择

中小企业较之大型企业具有技术创新方面的诸多优势,但也存在不利于其发展的种种因素。完善的法律体系是中小企业利用自身优势和克服发展瓶颈进行技术创新的重要保障。通过考察国外中小企业技术创新的法律环境,梳理我国现有法律法规政策,选择出以专门法为中心,以相关配套法律法规调适与创新为重点,以地方政府法规政策推进为关键的法律保障路径。     

高校协同创新模式选择影响因素实证研究

“2011计划”明确了面向科学前沿、面向文化传承创新、面向行业产业、面向区域发展的高校协同创新模式类型,要求高校协同创新中心合理选取模式,分类型申报、培育、考核、验收。通过经评审认定、已挂牌运行的82个高校协同创新中心的126份有效问卷,实证研究了科研能力、创新文化、协同战略、协作资源、协作关系、物理距离对于不同协同创新模式选择的影响作用,可为高校协同创新模式选择提供概念模型与实证参考。     

Politics, selection and the public interest: Besley’s benevolent despot

This paper is an assessment of Besley’s attempt to orchestrate a rapprochement between public choice theory and conventional public economics—with its characteristic normative orientation towards public policy. In this paper, I first try to set the Besley enterprise in the context of earlier work—focussing on my own work with Buchanan (The Power to Tax and The Reason of Rules). I then direct attention to three aspects of the Besley enterprise: whether selecting for competence depends on having solved the motivation problem (either by incentive or selection means), how selection mechanisms might be supported institutionally and the possibility that selection processes might create incentives at the ‘dispositional’ level.
