Statistical estimate of the proportional hazard premium of loss

The well known Proportional Hazard Premium Principle, introduced by Wang (1996), depends upon the survival function of the insured risk and a risk aversion index. Using this premium principle, we propose an asymptotically normal semi-parametric estimator for the net-premium of a high-excess loss layer of heavy-tailed claim amounts. An algorithm to compute confidence bounds is given. Moreover, a comparison between this estimator and the non-parametric estimator, proposed by Necir & Boukhetala (2004), is carried out.     

Using dimensions of moral intensity to predict ethical decision-making in accounting

The paper addresses the persistent problem of graphical communication in financial reporting. The lack of appropriate curriculum development for students' professional guidelines may arguably perpetuate poor practice. The multifaceted perceptual issues, strategic use and design issues involved in this visual medium for financial reporting are discussed. There are decision-making processes involved in using graphical displays. The paper presents a comprehensive set of guidelines along with practical insights for the effective use of graphical displays. It may serve as a critical (self)learning tool.     

政策性负担与长期预算软约束

经济学家们很早就注意到了政策性负担对预算软约束的影响,然而现有的有关政策性负担的理论模型主要集中讨论政策性负担与企业补贴的关系,但企业补贴并不等于预算软约束。为此,本文首先建立了一个简单的三阶段动态博弈模型,在该框架下我们可以准确地定义预算软约束问题,并分析政策性负担对预算软约束的影响。然后,我们利用重复博弈的思想将本文的基本模型动态化,建立了长期预算软约束的基本理论框架,这在现有的预算软约束文献中是不多见的,有助于更加全面地考察影响政策性负担、预算软约束和道德风险问题的各种因素。本文的主要结论是,政策性负担是导致企业出现预算软约束问题的重要根源之一,但如果政府和企业之间的博弈可以重复进行,预算软约束问题能够得到有效缓解。     

Retailers' major ethical decision making constructs

The major constructs of the Ferrell and Gresham [Ferrell OC, Gresham L. A Contingency Framework for Understanding Ethical Decision-Making in Marketing. J Mark 1985; (Summer): 87-96.], Hunt and Vitell [Hunt SD, Vitell S. A General Theory of Marketing Ethics. J Macromark 1986; 6 (Spring): 5-16.], and Ferrell et al. [Ferrell OC, Gresham L, Fraedrich JP. A Synthesis of Ethical Decision Models for Marketing. J Macromark 1989; 9(2) (Fall): 55-64.] models were tested using LISREL. Our findings suggest that Friends, Superiors, Business Associates, and Formalization of the Organization are more significant than Moral Philosophy. A new construct Ethicalness, comprised of individual, organizational, and societal value structures yielded a tight multi-dimensional fit that supports Kerlinger's domain theory and is dissimilar to Reidenbach and Robin's (1991) multi-dimensional scale. This research is one of the first to test as many ethical decision making constructs while explaining the multi-dimensional conundrum of ethical/unethical and legal/illegal practices within retailing.     

Survival of high tech firms: The effects of diversity of product–market portfolios, patents, and trademarks

High tech firms can mitigate potential risks by diversifying their product–market portfolios. A key research question is how such diversification influences firm survival. A firm exits the market in two ways, specifically, dissolution and acquisition. Here, we model how the diversity of a new firm's product–market portfolio influences the times to both types of exits. Specifically, we allow for interaction effects of the competitive intensity of a firm's environment and the diversity of a firm's product–market portfolio with its patents and trademarks. Using a competing risk hazard model, we estimate the effects of various covariates on the time to exit for 1435 US high tech firms.We observed that a more diverse product–market portfolio, in conjunction with a larger number of patents, hastens the time to a firm's exit by dissolution (9% decrease in survival duration), while in conjunction with a larger number of trademarks, portfolio diversity delays the time to exit by dissolution (12% increase). A more competitive firm environment results in a greater effect on the portfolio's diversity in delaying its exit by dissolution (7% increase). On the other hand, a diverse product–market portfolio, combined with either a larger number of patents or trademarks, hastens the firm's exit by acquisition (19% and 11% decrease respectively).     

新兴市场合资企业R&D强度与企业绩效或有关系及调整

MNCs（跨国公司）通过组建合资企业进入新兴市场,由于其R&D活动面临着创新专用性风险,使其R&D强度与合资企业绩效之间表现为一种或有关系。使用厦门、长沙和重庆3地制造业样本检验验证了该理论假设。就市场战略而言,只有那些以国际市场战略为主的合资企业才能获得R&D对合资企业绩效的促进效应;进一步考虑合资企业不同的所有权结构——市场战略配置结构,发现只有在以国际市场战略——MNCs占绝对多数股权的合资企业中,R&D强度对企业绩效的促进效应才会显现,而其它任何类型的配置结构均没有发现这种促进效应。这些发现可为中国完善外资政策提供理论指导。     

Leaving the darkness: The emergence of shadow banks

This paper studies the interaction between bank capital regulation, moral hazard and co-existence of traditional and shadow banks. Bank managers can choose between traditional banking and off-balance sheet special purpose vehicles (SPV), in a setup with deposit insurance and moral hazard. We first show that in the absence of SPV intermediation, capital requirements are ineffective at preventing the moral hazard problem originated by deposit insurance. We find that shadow banks can improve financial stability, when there is full information sharing. Finally, we analyze the case of neglected tail risk. We find that under such circumstances, the SPV will increase financial risk by exposing the system to extreme events.     

银行危机救助策略的分析

银行危机的救助策略一直是理论界关注的焦点。本文通过构建一个两期模型,以银行危机是否会引发货币危机为评判标准,探讨政府在面对商业银行清偿能力危机时救助与不救助的抉择。经研究发现:当商业银行的不良资产率高,或商业银行在经济中起重要作用,抑或产出的价格弹性较小时,为了避免货币危机的发生,政府应该出手对商业银行提供救助。在相反的情况时,固定汇率制度下,政府为了维护其固定汇率的信誉应该出手对商业银行提供救助;浮动或管理浮动汇率制度下,考虑到商业银行的道德风险问题,政府应该不予以救助。     

金融创新如何缓解信任品市场失灵?——中国食品安全责任强制保险的自然实验

信任品市场(如食品、医药等)存在的问题一直困扰着中国和世界很多国家。关于产品和服务质量的信息不对称(道德风险和逆向选择)会导致信任品市场失灵。缓解信任品市场失灵,一种常见的解决方案是政府监管;而经济学家认为更加基于市场的解决方案(例如强制责任保险等金融创新)可能更为有效。在理论上,强制责任保险有两种相反的效应:保险公司的监督减少了道德风险 vs. 保险加剧了企业的道德风险,但一直亟待实证检验。幸运的是,中国食品安全责任强制保险的改革实验走在了世界的前列。本文利用了中国在不同地区、不同时间推行的这个自然实验,通过双重差分的方法识别出责任保险对于信任品市场的因果效应。本文的研究发现,强制责任保险能显著降低食品安全事故发生概率。这表明政府强制推行的金融创新可以成为信任品市场失灵的一种有效的替代性解决方案。     

The influence of auditor narcissism and moral disengagement on risk assessments of a narcissistic client CFO

Global capital markets rely heavily on independent and skeptical auditors as gatekeepers to provide assurance that corporate financial reports are free of material fraud. The rise of narcissism among the ranks of both client and audit professionals challenge this gatekeeper function. In addition, auditor moral disengagement may undermine auditor skepticism, further eroding public confidence in the integrity of financial reporting and the audit process. We conduct a quasi-experiment with 118 auditors from three international audit firms. In a simulated interview with a client CFO, we examine whether auditors underestimate risks of fraudulent financial statements due to the interactive effects of (1) client narcissism (manipulated verbally and nonverbally) and (2) auditor narcissism. We also examine the influence of auditor moral disengagement on client risk assessments. Results indicate that CFO verbal and nonverbal narcissism significantly influenced auditors’ assessment of management-related client risk. Moreover, auditor narcissism was found to interactively influence client risk inferences such that auditors higher in narcissism exhibited narcissistic tolerance (lower risk assessments) when the hypothetical CFO displayed high verbal narcissism. Auditor moral disengagement was negatively associated with client risk assessments. We discuss the implication of these findings on future audit judgment research, audit firm policy and training on maintaining auditor skepticism, and the audit oversight role of standard-setters.
