在线服务失败类型对平台卖家声誉的影响研究北大核心CSSCI

随着平台型电商的快速发展,买家经历的服务失败也日益增多,在线服务失败不但给平台卖家声誉造成负向影响,且不同服务失败类型对平台卖家声誉的影响效应有所不同。本文通过在线服务失败相关研究的梳理,将在线服务失败类型划分为未达到平台规则和未达到卖家承诺两种,并采用实验法探讨了在线服务失败类型对平台卖家声誉的影响以及外部归因的中介作用,在此基础上进一步考察了卖家评分(高评分vs.低评分)和平台型电商声誉(高声誉vs.低声誉)的调节作用。实验结果显示:较之未达到平台规则,平台卖家所提供的商品/服务未达到卖家承诺时,买家对平台卖家声誉的评价更低;买家的外部归因可以中介在线服务失败类型与平台卖家声誉之间的关系;对于高评分卖家来说,外部归因的中介效应更为显著;对于高声誉平台型电商,外部归因在在线服务失败类型和平台卖家声誉之间的中介效应更为显著。本文的研究结论为平台卖家的声誉管理和在线服务失败补救提供了有益的经验借鉴,也丰富了网络消费者行为的相关研究。     

网上交易中的私人秩序-社区、声誉与第三方中介

网络扩大了市场范围,减少了信息收集成本和信息传播成本,使买家和卖家更容易配对。但是,网上C2C交易中也存在着严重的囚徒困境问题。交易网站以及其他第三方中介建立了信用评价等一系列机制来解决网上交易的治理。本文主要探讨在法律制度不完善或法律不能很好发挥作用的情况下,交易方以及追求利润最大化的第三方中介如何建立起私人秩序来保证交易的顺利进行。这些私人秩序在一定程度上起到了替代法律这种公共秩序的作用。

保证金制度下C2C逆向物流平台定价研究

基于双边市场理论,引入保证金制度,建立5种定价模型,为C2C逆向物流平台选择均衡定价决策提供参考。研究发现,双寡头竞争市场中任一平台不会率先收取保证金,保证金的收取有可能使得平台对用户收取的注册费为负,并且5种定价模式中,大部分情况下平台选择对卖家收取保证金、对买家收取注册费时平台获取的利润最大。     

信用、社会资本与企业孵化行为研究——基于行为理论的分析

本文基于行为理论,构建了企业孵化行为模型,并推导出企业孵化网络进化的稳态方程.在企业孵化网络中被孵企业拥有社会资本,且影响社会资本的关键因素是可信度,在具有较高社会资本的企业孵化网络中,被孵企业所作出的承诺,即使不能使他们获得最大的经济利益也是值得信任的.契约的不确定性导致契约设计并不能解决孵化网络运行机制中的所有问题,声誉、信用与契约对企业孵化网络运行的影响同等重要.声誉是形成契约的基础,但仅靠声誉是脆弱的,只有在相互信任的基础上,依靠契约及共同遵守的行为规范才能保证企业孵化网络的正常运转.     

网络借贷中信息不对称缓解机制研究*——基于信号传递和双边声誉视角

本文借助于“人人贷”平台的微观数据从信号传递和双边声誉两个视角研究了网络借贷平台信息不对称问题的缓解机制。研究发现网络借贷平台的学历信号和双边声誉机制有助于减缓信息不对称程度，提高金融服务效率，增进资源的合理配置，降低融资后的道德风险。同时，本文还发现借款人的学历信号和双边声誉存在非对称的替代关系，高声誉更能弥补低学历借款人信誉信号的不足，因此低学历借款人更有激励建立自身的高声誉，但是随着借款人学历的提升，该非对称效应消失。进一步研究发现，学历信号和双边声誉机制在缓解借贷双方的信息不对称问题上存在较大的区域差异。本文的研究对于缓解“长尾人群”的融资约束提供了一种新的思路。     

非正式社会结构下民间信用演进与生命周期

在非正式制度为主导的农村非正式社会结构中,基于特殊信任主义的民间信用,其博弈主体由于交易域和社会交换域的关联博弈和基于声誉的私人契约执行机制,使得民间信用契约具有自我执行的内在机制.随着农村非正式社会结构的制度转型,使得特殊信任主义向一般信任主义演变,并促使中国民间信用制度沿着其生命周期轨迹发生适应性变迁.     

竞争对第三方标记有效性的异质性影响:理论与实证

网络交易市场中卖家数量增多导致的竞争加剧会对第三方标记这一信号传递机制的有效性产生影响。在信号传递的理论框架下,对分离均衡和混同均衡在双边垄断以及竞争市场中的分析发现,竞争加剧对第三方标记的有效性存在着异质性的影响:当买家对不同类型卖家的意愿支付差异高于诚信卖家的标记成本且小于投机卖家的标记成本时,竞争加剧会损害第三方标记的有效性;但是当不同类型卖家的标记成本彼此之间差异较大,而又都低于买家的意愿支付差异时,第三方标记的有效性会随着竞争加剧先上升后下降。对淘宝网上多种主流第三方标记在不同竞争环境下的实证分析与效果对比也为上述结论提供了经验支持。     

Pleasure and belief in Hume's Decision Process

Abstract

The purpose of this paper is to introduce explicitly pleasure and belief in what aims at being a Humean theory of decision, like the one developed in Diaye and Lapidus (2005a). Although we support the idea that Hume was in some way a hedonist – evidently different from Bentham's or Jevons' way – we lay emphasis less on continuity than on the specific kind of hedonism encountered in Hume's writings (chiefly the Treatise, the second Enquiry, the Dissertation, or some of his Essays). Such hedonism clearly contrasts to its standard modern inheritance, expressed by the relation between preferences and utility.

The reason for such a difference with the usual approach lies in the mental process that Hume puts to the fore in order to explain the way pleasure determines desires and volition. Whereas pleasure is primarily, in Hume's words, an impression of sensation, it takes place in the birth of passions as reflecting an idea of pleasure, whose “force and vivacity” is precisely a “belief”, transferred to the direct passions of desire or volition that come immediately before action. As a result, from a Humean point of view, “belief” deals with decision under risk or uncertainty, as well as with intertemporal decision and indiscrimination problems.

The latter are explored within a formal framework, and it is shown that the relation of pleasure is transformed by belief into a non-empty class of relations of desire, among which at least one is a preorder.     

Globalization,Neoliberalism and the attack on social security

Neoliberal political movements advocate privatization of public pension systems. Globalization imposes pressure on nations to conform to neoliberal policy views with respect to the design and structure of social insurance, including public pension systems. The paper begins with an investigation of the economic, ethical and ideological dimensions of the privatization debates in the U.S.; it argues that privatization advocates may be largely moved by ideology, since the other reasons advanced appear weak or unfounded. The second part discusses the history of Social Security, the purposes for its creation, and some of its economic effects. Differences between public and private pension systems are considered. A brief international comparison of some aspects of public pension system finance and benefit structures is presented. The final section considers the ethical, macroeconomic and distributional implications of privatization, prefunding and payroll tax funding, and argues for a pay as you go system financed with income taxes. In order to promote equity, economic security, community, and social cohesion, public pension systems should be universal in coverage. In order to reduce the inequality, income insecurity, and aged poverty generated by market economies, public pension systems ought to be progressive: benefit/contribution ratios should be inversely proportional to income, and progressive income taxes should finance the system. To promote economic growth, the systems should be financed on a pay-as-you-go basis, and should not be prefunded except for an emergency reserve. The fiscal policy recommendations partially depend upon the theory developed by Abba Lerner in the 1940s, and recently advanced by Wynne Godley and Randy Wray: Lerner's “principle of functional finance.”     

John Stuart Mill's Theory Of Justice

John Stuart Mill has traditionally been portrayed as self-contradictory and failing to construct a unified social theory. Recent scholarship, however, has challenged this view, finding Mill's work to be creatively synthetic in bridging the antinomies inherent in liberal democratic thought. This revisionist interpretation of Mill is advanced by an understanding of his theory of justice and its role in shaping his policy positions on issues such as welfare, education, voting rights, property rights, taxation, government intervention, and the future of capitalism.

Interest on reserves and inflation

The payment of interest on reserves has been a common practice in inflationary economies. This policy may seem paradoxical since it involves returning part of the seigniorage, generated by the inflation process, with the intention to finance the fiscal deficit. This paper argues that the motivation for this policy can be captured by the discretionary regime, where the policymaker pays interest on reserves because he is concerned with the erosion of real liquidity by inflation, which is in part beyond his control. However, this policy is an unlikely outcome in the commitment regime, where the policymaker is in full control of inflation.
