真实型领导对员工越轨创新行为的影响——组织自尊与建设性责任认知的链式中介作用及差错反感文化的调节作用

应用社会学习理论、社会交换理论和三元交互决定论，基于365份领导-员工配对数据，构建一个被调节的链式中介模型，以组织自尊和建设性责任认知为中介变量，差错反感文化为调节变量，探讨了真实型领导风格对员工越轨创新行为的影响。实证结果发现：真实型领导正向影响员工越轨创新行为；组织自尊、建设性责任认知分别在真实型领导与员工越轨创新行为间起部分中介作用，并共同在真实型领导与员工越轨创新行为间发挥链式中介作用；差错反感文化负向调节真实型领导与员工越轨创新、组织自尊与员工越轨创新、建设性责任认知与员工越轨创新的关系。     

风险规避与农地租约期限选择——基于广东省农户问卷的实证分析

长期且规范的合约安排是降低要素市场交易风险和保障参与者预期收益的重要基础,但农地租约却普遍存在缔约短期化问题。其中,农户的风险预期是影响其农地租约期限的重要因素,而风险预期既可能是源于缔约对象之间的信息不对称,也可能是合约本身的不完全。因此,文章重点考察农户风险规避对其农地租约期限的影响,并从信息不对称和合约不完全两个维度阐述农户农地流转中风险的形成及其影响。实证结果表明,农户对承租方了解越多,尤其是与亲友邻居更可能基于关系信任而形成短期租约,而租约中的违约惩罚条款则能够弱化机会主义行为,有助于激励农户选择长期租约。由此,进一步阐述了目前农户农地流转受到社会关系与市场影响,导致其缔约行为兼有差序格局与商业交往的双重特征。     

中国股权溢价之谜的检验--Hansen-Jagannathan方法的应用

通过对中国证券市场的实证研究,估计的中国投资者的相对风险回避系数远远大于10,即远大于Mehra和Prescott(1985)所认可的最高水平,证实了中国股市存在股权溢价之谜,并指出了解释中国股权溢价之谜的潜在研究路径.     

Insurance and Incentive Effects of Transfers among Regions: Equity and Efficiency

When productivity shocks across regions are less-than-perfectlycorrelated, there are gains from federation, even if the regionsare identical ex ante. For the federation to provide insurancefor these productivity shocks, it must introduce some sort ofequalizing transfer programme among regions. But any suchtransfer programme induces a form of moral hazard as well, ifregions still have some control over their own policies. Oneof the implications of this moral hazard is that the progressivityof the overall (regional together with federal) tax system willbe increased when the federal transfer programme is expanded.     

Mapping symbolic (anti-) consumption

Rejection is at the heart of anti-consumption and is therefore key to some of the central relationships in symbolic consumption. However, researchers find rejection difficult to study because of the lack of material traces. This article draws on earlier frameworks to develop a new integrated and expanded conceptualization in order to achieve a more nuanced view of how rejection operates within symbolic consumption; and also to initiate research directions for investigating and theorizing rejection in anti-consumption. The focus on anti-consumption incorporates the interaction between avoidance, aversion and abandonment, and the relationship between distastes and the undesired self (mediated by the marketing, social and individual environments). A series of interrelationships and illustrations suggest how the expanded conceptualization is useful for theorizing and investigating anti-consumption.     

WELFARE AS EQUITY EQUIVALENTS

Equity (or, its counterpart, inequity) plays a fundamental role in the evaluation of social welfare in different dimensions. In this paper, we revisit the concept of inequity – in the sense of unequal distributions – across individuals, time, and states of the world using a unified framework that generalizes the standard expected discounted utilitarianism approach. We propose a general measure of welfare as equity equivalents and a corresponding inequity index. We show that allowing for different attitudes toward inequity across different dimensions covers a scope of possible inequity preferences with different interpretations. We then prove that the order of aggregation across the different dimensions matters for welfare evaluations. Finally, we show that many of the welfare-theoretical approaches recently developed in the literature can be interpreted as special cases of this general framework.     

超越经济人的社会偏好理论:一个基于实验经济学的综述

实验经济学对传统经济人假设的系统反驳促使社会偏好理论应运而生.社会偏好理论的各个模型试图在维持理性假设下,通过将基于心理学和社会学的诸如公平、互利等与“自利”假设有着明显涵义辨识度的一些人类社会性情感因素纳入到效用函数中来进而修正经济人假设,并以博弈论为基本的分析工具力图构建新的博弈均衡来解释实验经济学所揭示的一系列悖论.本文围绕社会偏好在已有文献的基础上对其产生的背景、模型、测度、外溢以及检验等问题作了一个详细而系统的梳理     

过度自信、后悔厌恶与收益率分布非正态特征

过度自信与后悔厌恶是投资者普遍存在的两种心理偏差.通过过度自信与后悔厌恶对证券市场收益率分布的影响的定性分析可知:这两种心理偏差会造成证券市场收益率分布左偏,而且与正态分布相比较存在失峰厚尾现象;特别是随着时间单位的增大,收益率分布的尖峰厚尾呈递减的趋势.利用深圳成分指数和上海综合指数进行的实证研究发现,中国股票市场的收益率分布存在上述现象.     

Betrayal intention in exporter-importer working relationships: Drivers,outcomes, and moderating effects

Betrayal is a very common, but relatively under-researched, dark side phenomenon in inter-firm relationships that warrants investigation. We propose a conceptual model of the factors reducing betrayal intention in exporter-importer (E-I) working relationships and its resulting effect on actual betrayal. Using a random sample of 262 indigenous exporters of manufactured goods based in Greece, we confirm that betrayal intention in their relationships with foreign buyers is significantly and negatively affected by four key parameters, namely, trust, communication, long-term orientation, and social bonds. An importer’s betrayal intention is subsequently very likely to develop into actual betrayal in the relationship. However, this likelihood is lower in the case of older relationships, as well as those characterized by contractual obligation between the interacting parties.     

2010年亚运会特许商品市场分析

随着金融市场理论研究和实践检验的不断发展,资本市场的许多基础理论受到了极大的挑战,与现有理论相悖的异象不断涌现。新近兴起的实验经济学为人们研究资本市场提供了一条更为有效的途径。本文分析了实验方法在资本市场研究中的利与弊,介绍了部分资本市场实验的设计过程,并应用该方法分析了风险与收益、资本市场的效率、市场泡沫的产生和破灭、CAPM理论,以及交易制度等。文章指出,在资本市场中运用实验方法进行研究,具有可控性、可比性以及可重复性等优点,为我们对于资本市场诸多理论进行检验提供了可能。在资本市场实验的设计中,我们不但需要考虑实验的各种交易制度,还需要考虑到被试人员的选择、交易资产的确定以及市场信息的设计等很多问题,只有对这些问题进行全面地考虑,才能保证实验结果的可信度,进而为我们对于各种金融理论的检验提供可能。
