Victory margins and the paradox of voting

This paper addresses a simple question: why do people vote? Though simple, this question remains unanswered despite the considerable attention it has received. In this paper, I show that purely rational–instrumental factors explain a large fraction of turnout variations, provided that the effect of the margin of victory on implemented policy is considered. I extend Myerson's models of elections based on Poisson games, and show that, when platforms are responsive to vote shares, the predictions of the model become consistent with several stylized facts, including the secular fall in turnout rates in the US.     

悖论思维对创造力的“过犹不及”效应研究

悖论思维帮助个体发现对立事物间的联系,有利于创造性想法或创意的生成,但过高水平的悖论思维极易导致认知过载,使个体无暇顾及需要想象力和灵感的创造性活动。基于"过犹不及效应",本文提出悖论思维对员工创造力产生非线性影响。同时,根据能力-动机-机会(AMO)的理论框架,探索个人学习能力在这一关系中的中介作用,以及领导调节聚焦行为的调节作用。本文认为:悖论思维与员工创造力呈倒U型关系,个人学习能力在上述关系中起中介传导作用,领导促进型聚焦行为强化了变量间的间接关系,而领导防御型聚焦行为削弱了变量间的间接关系。通过对313名员工的三阶段调查分析,数据支持了本研究提出的假设。虽然适度的悖论思维有助于员工提升学习能力,但过度的悖论思维反而会降低员工学习效率进而削弱员工创造力,领导调节聚焦行为决定了员工是否能完成学习能力到创造力的转化。研究结论为员工创造力的影响因素研究提供了新思路,引导企业通过甄选员工和调整领导行为来激发员工创造力。     

埃尔斯伯格悖论评析

主观期望效用理论认为个体的概率分布可以由行为的偏好导出,并且理性人的行为选择应该遵循主观期望效用理论,但是,埃尔斯伯格悖论显示了没有一个主观的概率测度,而且实际行为的选择并不总是和该理论的结果相一致。因此,围绕埃尔斯伯格悖论,展开了行为决策理论应该是规范的还是描述的争论。     

Does institutional quality resolve the Lucas Paradox?

The Lucas Paradox observes that capital flows predominantly to relatively rich countries, contradicting the neoclassical prediction that it should flow to poorer capital-scarce countries. In an influential study, Alfaro, Kalemli-Ozcan, and Volosovych (AKV) argue that cross-country variation in institutional quality can fully explain the Paradox, contending that if institutional quality is included in regression models explaining international capital inflows, a country’s level of economic development is no longer statistically significant. We replicate AKV’s results using their cross-sectional IFS capital flow data. Motivated by the importance of conducting inference in statistically adequate models, we focus on misspecification testing of alternative functional forms of their empirical model of capital flows. We show that their resolution of the Paradox relies on inference in a misspecified model. In models that do not fail basic misspecification tests, even though institutional quality is a significant determinant of capital inflows, a country’s level of economic development also remains a significant predictor. The same conclusions are reached using an extended dataset covering more recent IFS international capital flow data, first-differenced capital stock data and additional controls.     

Approaching paradox: Loving and hating mega-events

This paper examines the role of paradoxes in research and proposes strategies of engaging with them. For this purpose, it analyses the ways in which six paradoxes are constitutive of sports mega-events such as the Olympic Games: the universalism paradox, the compliance paradox, the winner's paradox, the participation paradox, the uniqueness paradox and the passion paradox. It then develops three strategies of how researchers and practitioners can approach paradox. The first, exploration, examines the consequences and effects of the ambiguity of paradoxes. The second, differentiation, enquires into the spatio-temporal and social make-up of paradoxes. The third, reframing, recasts paradoxes by shifting theoretical perspectives. Instead of pressing to resolve paradoxes, researchers and practitioners alike should make productive use of their ambiguity.     

The paradoxes of risk management in the banking sector

This paper uses empirical evidence to examine the operational dynamics and paradoxical nature of risk management systems in the banking sector. It demonstrates how a core paradox of market versus regulatory demands and an accompanying variety of performance, learning and belonging paradoxes underlie evident tensions in the interaction between front and back office staff in banks. Organisational responses to such paradoxes are found to range from passive to proactive, reflecting differing organisational, departmental and individual risk culture(s), and performance management systems. Nonetheless, a common feature of regulatory initiatives designed to secure a more structurally independent risk management function is that they have failed to rectify a critical imbalance of power - with the back office control functions continuing to be dominated by front office trading and investment functions. Ultimately, viewing the 'core' of risk management systems as a series of connected paradoxes rather than a set of assured, robust practices, requires a fundamental switch in emphasis away from a normative, standards-based approach to risk management to one which gives greater recognition to its behavioural dimensions.     

论数据分组的误导作用

对数据分组之后再进行处理是一种常见方法,但是这种方法可能产生错误结果.本文搜集了几个实际的数据分析案例,说明对数据的分析可以是任意的,但是对分析结果的解释必须受制于研究对象和周围条件.本文结合案例提出了一些避免分组陷阱的手段,还提供了理解辛普森悖论的一个角度.     

农村集体建设用地流转地权的激励模式

农村集体建设用地流转中存在严重的资金时差悖论,导致难以利用集体土地本身进行融资,土地整理融资难反过来又成为阻碍集体建设用地流转的瓶颈性因素。现有流转模式难以协调各种利益,不能对流转各方产生足够激励,变相征地的方式削弱了农民的土地持续收益能力,未能真正实现城乡建设用地"同质、同价、同权"。因此,应根据利益协调的原则创新制度设计,以地权激励引导社会资源投入,促进集体建设用地顺畅流转。     

高星级酒店业的信息技术“生产率悖论”研究——基于广州案例

信息技术与酒店业的结合给酒店业带来了新的发展机会.国外有大量的学者致力于信息技术投资与企业生产率及业绩之间关系的研究,但并没有一致的结论.文章通过对广州市高星级酒店的相关调查,获取了第一手数据,借助AMOS软件的验证性因子分析及SPSS软件的相关性分析和多元回归分析功能,以检验信息技术的应用对酒店业绩的影响.结果显示,信息技术“生产率悖论”在高星级酒店业内不存在,前厅应用、客人相关界面应用、餐厅及宴会管理系统及后台应用均对酒店业绩有积极的作用.其中,客人相关界面应用对酒店业绩影响最大,因此应着重投资.文章的结论将为高星级酒店业决定是否战略性地投资于信息技术或集中于某些特定领域提供重要的信息.最后,文章还对研究的局限性以及后续可以开展的研究进行了一定的展望.
