基于信号博弈的卖方欺诈行为分析

本文主要基于信号博弈的卖方欺诈行为进行研究，假设拍卖中可能存在欺诈型和诚实型两种卖家，其中欺诈行为有概率发生在第二价格拍卖中：欺诈型卖方冒充竞拍者递交仅次于最高价的报价从而获得额外收益。两种卖家根据各自效用选择拍卖形式：第一价格或者第二价格。而竞买者将卖者的选择作为信号，更新对卖方类型的判断，然后制定报价策略。这是一个买卖方信号交叉影响的过程。考虑到拍卖过程中买方价值相关性，本文在建立模型中参考了关联价值原理。针对该模型进行分析，得出了不同情况下的买卖方策略，并且研究了买方报价、买方判断、卖方收益三者之间的关系。文中利用贝叶斯公式对双方的策略选择问题进行预测，与单纯的概率分布方法相比，更具实践价值。     

The limits of the decentred state: the case of policing insurance claims fraud

Existing research clearly shows that the public–private divide is continuously being challenged, recast and transformed. However, this article argues that a sharp distinction between public and private continues to operate as an important norm for professionals involved in the investigation of insurance claims fraud in Sweden. It shows how power within private insurance companies and the police authority is organized around the public–private divide, which is in turn mobilized to justify repression and to give investigations legitimacy. The article indicates that the formal public–private distinction is far more thoroughly maintained than is suggested by the existing literature. Rather than challenging the centrality of state power, private insurers and the police construct, maintain and have a stake in the reproduction of a state‐centric monopoly of crime control.     

社会信任对公司违规的抑制性研究

如何防范公司违规、保护投资者利益是资本市场研究的热点问题。以2010-2017年沪深两地A股2853家上市公司为研究样本,基于部分可观测的Bivariate Probit模型的实证结果显示：公司所在地区的社会信任水平越高,其违规倾向越低,被违规稽查的概率则越高;进一步研究发现,风险喜好型高管会降低社会信任对公司违规倾向的抑制作用,并在一定程度上强化了社会信任对公司违规稽查的影响力度;此外,相较于信息披露违规,社会信任对经营违规倾向的抑制作用更为显著,并且更为有效地提高了经营违规被稽查的概率。     

The victim–offender overlap in late adulthood

This study contributes to the general knowledge of the victim–offender overlap by determining whether the phenomenon exists among older adults and whether known correlates of crime and victimization explain the relationship. Cross-sectional survey data from telephone interviews conducted with individuals 60 years and older (N = 2,000) residing in Arizona and Florida are used to estimate confirmatory factor models for both victimization and criminal offending. The results from a series of multivariate regression models show that victimization is associated with criminal offending. While factors such as low self-control, depression, and spending time in commercial drinking establishments partially attenuate the victimization–crime link, the statistically significant relationship persists in a multivariate context. Further testing indicates that the observed findings are robust across measurement and modeling strategies. Coupled with prior research, the results support the argument that the victim–offender overlap exists (and is difficult to explain) over the life course.     

Both Whistleblowers and the Scientists They Accuse Are Vulnerable and Deserve Protection

Whistleblowers play an important role diagnosing research misconduct, but often experience severe negative consequences. That is also true for incorrectly accused scientists. Both categories are vulnerable and deserve protection. Whistleblowers must proceed carefully and cautiously. Anonymous whistleblowing should be discouraged but cannot be ignored when the allegations are specific, serious, and plausible. When accused of a breach of research integrity it is important to be as transparent as possible. Sometimes accusations are false in the sense that the accuser knows or should know that the allegations are untrue. A mala fide whistleblower typically does not act carefully and we postulate a typology that may help in detecting them. Striking the right balance between whistleblower protection and timely unmasking false and identifying incorrect accusations is a tough dilemma leaders of research institutions have to face.     

网上创新竞争中解答者对发布者的信任问题研究

困扰网上创新竞争发展的一个重要因素是发布者作弊问题,它降低了解答者对发布者的信任,网络平台也采取各种方法监督作弊行为。为此,研究2个紧密关联的问题:①影响解答者对发布者信任的因素;②网络平台如何设定合适的监督水平。对问题①,基于信任理论构建研究模型,通过大样本问卷调研检验假设,结果表明:现有的信誉机制作用不显著,而网络平台本身的信誉和解答者满意度对信任有显著影响。实证研究结果凸显了网络平台服务水平的重要性,也是研究问题②的驱动因素。问题②的研究方法是博弈论,通过逆向求解,分析网络平台如何平衡成本和信誉来制定监督水平。最后,给出了主要结论以及未来的研究方向。     

商业贿赂的会计途径及其防范

商业贿赂业已成为当前我国经济生活中的一个突出问题,其支出往往通过不记入财务账、转入其他财务账中或者做假账等非正常途径进入会计信息系统,阻碍了市场经济的健康发展。分析其中原因,竞争机制滞后、权力寻租、制度建设不健全是主要方面。治理商业贿赂应从完善法律制度、完善会计制度、构建反商业贿赂社会会计监督联动体系方面进行。     

表见合伙之价值评判——兼析新《合伙企业法》第76条

2007年6月1日开始实施的新《合伙企业法》是一部非常有效地法律,但其最大缺陷是仍然没有规定表见合伙制度。表见合伙与表见代理、与民事欺诈是有明显区别的,不能用表见代理与民事欺诈解决实践中的表见合伙纠纷。新《合伙企业法》第76条的规定让人困惑,像似表见合伙,实则不然。建立表见合伙制度更有利于保障交易公平和安全,彰显善意第三人的利益,充分救济善意第三人的权利。因此,我国应当建立表见合伙制度。     

诈欺不法原因给付财物与利益之刑法分析

诈欺基于不法原因给付的财物或者财产性利益的场合下是否成立诈骗罪,德国、日本和我国的立法、判例和学说都有所不同。在诈欺的对象是财物的场合下,基于不法原因给付的财物在因诈欺行为交付之前,也是民事法上保护的对象等原因,应当肯定诈骗罪的成立。在诈欺的对象是财产性利益的场合下,不法利益本身并非民事法上应当得到保护的利益,不应得到刑法保护,应否定财产罪的成立。     

A Mechanical Interpretation of the Coefficient of Rank Correlation and other Analogies

Periodically, the pyramid or “chain letter” scheme is offered to Americans under the guise of a business dealership. Recently, the FTC ordered Glen Turner's “Dare to be Great” firm to repay 44 million dollars to participants. In order to demonstrate that the potential gains are misrepresented by promoters, a probability model of the pyramid scheme is developed. The major implications are that the vast majority of participants have less than a ten percent chance of recouping their initial investment when a small profit is achieved as soon as they recruit three people and that, on the average, half of the participants will recruit no one else and lose all their money.
