Congestion effects in a public-good economy

This paper considers a public-good economy with congestion, where participants jointly produce a public good from input of a private good. This economic model gives rise to a transferable-utility game, the profit game, that depends on consumer preferences and a congestion parameter. The simplicity of the game allows the maximum level of congestion that guarantees the nonemptiness of the core of the economy to be determined. It is known that the sustainability of the Lindahl equilibrium in the core of the economy depends on the distribution of profits. In this paper two distributions of profits are compared: the Lindahl solution and the marginal-contribution solution. The latter is more often in the core than the Lindahl solution which in turn Lorenz-dominates the marginal-contribution solution.     

转轨中国公共品导出机制中的政府行为分析

本文从政府角度出发,对公益品和私益品的特性进行了重新思考,从偏好、福利二分、绩效衡量难易、制度环境、意识形态等角度考察政府行为的独特性.并以我国体制转轨的特殊时期为背景,分析了不同于西方代议制的政体下,在公共品导出机制中政府行为的复杂性,指出了制度上的缺陷和由此导致的一系列现实问题.     

Tax Competition and International Public Goods

A well known result in the tax competition literature is that tax rates are set too low in the Nash equilibrium to finance an efficient level of public consumption goods. In this model we introduce international spillovers in public goods provision and show that such spillovers reduce, and in the limiting case of perfect spillovers, eliminate tax competition. There is, however, always underprovision of the public good in equilibrium, since larger spillovers increase the problem of free riding. In an extension to the model, we demonstrate that congestion costs may result in overprovision of the public good.     

关于社会保险的深层次思考

正确认识社会保险税并非一般意义上的税，而是介于税费之间，从而跳出了目前的费改税之争，对当前我国社会保障制度的构建具有重要的指导作用。关于社会保险模式的选择，结合我国实际，针对不同群体可选择“并列型和个人主导型”。运用收支两条线和提高社会保障立法层次构建起社会保障运行的制约机制。同时，要在工会的参与实施下，通过制度规则建企，构建社会保险的补充形式，如企业保险、社区互助等。     

自由软件开发的模块化理论解释与启示

本文以GNU/Linux为例讨论了源代码的内部结构在自由软件开发中所起的重要作用。为此,我们考虑了源代码的模块化属性。源代码的模块化将直接影响开发者是否参与对自由软件的开发。基于模块化的自由软件开发不仅实现了劳动的分工,同时也实现了劳动价值的分割,在自由软件的开发过程中较好地解决了搭便车问题。同时,模块化理论对我国发展软件产业也有一定的借鉴作用。     

银保协作、风险自留与银行信用风险补偿——基于银保信贷系统的分析视角

在分析风险自留的内生逻辑基础上,进一步分析风险自留实现银行信用风险补偿的内在机理。研究表明：银保信贷系统通过对贷款企业个体风险与事先设定的平均代偿风险的匹配性甄别,实现对银行信用风险的分级补偿功能。针对银行超预期信用风险,先行实施银行风险拨备机制对银行平均代偿风险进行补偿,然后实施超额风险自留机制对超过平均代偿风险的银行超额风险部分再次进行补偿,超额风险自留补偿基金将由银行与担保机构依据各自的风险均衡配置阈值占比共同筹集,以此来实现银行信用风险分级补偿目标。并以此为依据,设计了银保信贷系统风险自留机制。

株洲市农村养老保障情况调查及思考

中国已步入“未富先老”的老龄化社会,农村养老保障问题日趋凸显,株洲市更是进入了非常重要而又十分特殊的社会转型时期.本文分析了株洲市农村养老保障的现状、存在的主要问题以及产生问题的根源,针对这些问题提出了相应的对策建议.     

Can teaching social dilemmas make people more prosocial? An experiment

Economics and business students regularly behave less prosocially than others. Can ethics training reverse this tendency? Results from a repeated public goods experiment reveal that it can. Students who attend an interactive lecture on social dilemmas show significantly more cooperation than others. However, the lecture does not appear to increase the incidence of reciprocal behavior. As many current social problems qualify as social dilemmas, this result stresses the importance of ethics training for policy makers and curriculum designers alike in overcoming the incentive structure of social dilemmas.     

论儿童阶段教师权威地位的重要性——对“师生平等”的反思

“平等”概念进入教育领域后，为我们解决了一些困扰已久的师生关系问题。但这种看似民主的师生平等观点，是否也夹杂着整个社会的权威退化值得探讨。在权威普遍丧失的今天，教育领域中万万不能丧失权威的概念，师生平等并不是师生关系最高标准，它甚至有弱化教师权威的倾向。如何建立起师生关系的最佳模式，如何帮助教师重塑在学生心目中应有的权威地位，阿伦特的权威观念也许可以作为一个指引。
