Credit Events and the Valuation of Credit Derivatives of Basket Type

Thispaper provides a simple model for valuing a credit derivativewhose payoff depends on the identity (or identities) of the first(or first two) to occur of a given list of credit events, suchas defaults. The joint survival probability of occurrence timesof credit events is formulated in terms of stochastic intensityprocesses under the assumption of conditional independence. Basedon the joint survival probability, we can easily obtain the pricingformulas of such credit derivatives under the risk-neutral valuationframework. When the default intensity processes follow the extendedVasicek model, closed-form solutions of the pricing formulasare given.     

A Negotiation-Oriented Model of Auditor-Client Relationships

The increasing frequency and complexity of inter-organizational relationships suggests that inter-organizational negotiations should represent an area of increasing concern to management and academicians. Unfortunately, there is little theorizing about, nor study of, these negotiations. The few extant models are heavily influenced by models of individual negotiating styles that are then raised to the inter-organizational level with minimal change. The model developed here attempts to provide a framework for understanding the context of these inter-organizational negotiations by identifying and illuminating factors that influence the outcome of interactions in various long-term supplier relationships. Factors discussed include dynamic and stable environments, organizational cultures, role involvement, previous interactions between the individuals and organizations, and the unique characteristics of the decision-making processes that characterize the specific parties. As a framework for our presentation, we draw upon Kleinman and Palmon's (1999) theory of audit firm-client firm relationships, which is based on Kahn et al.'s (1964) Role Episode Model and Merton's (1966) Role Set Model. This paper incorporates Shakun's (1988) theory of evolutionary system design. The inclusion of the latter improves upon Kleinman and Palmon's work by first providing a better motive for the interaction between the parties, and second by shedding further light on the dynamics of the negotiation process.     

审计师变更与审计质量:一个理论分析

本文通过建立股东、管理层和审计师三方参与的两委托人-单代理人博弈模型,研究了固定审计费用下不同审计师变更方式对审计质量的影响。研究结果表明,审计师强制性单期变更与审计师强制性定期变更下,审计师与管理层之间的合谋将导致严重的财务舞弊;而在审计师自愿性变更下,股东可以利用解聘现任审计师这一威胁来阻止审计师和管理层之间的合谋,使得审计师和管理层的最优策略均为真实披露公司的盈余信息,并发表标准无保留审计意见。     

Auditor Independence,Current and Future NAS Fees and Audit Quality: Were European Regulators Right?

Abstract

European Union adopted the Regulation (EU) No 537/2014, which in practice prohibits the joint provision of audit and most types of non-audit services (NAS). Regulators presume that NAS fees weaken auditor independence and, as a result, impair audit quality. As the evidence at the European level does not support this view, the question of whether the new regulation will enhance auditor independence remains open. We examine the association between future NAS fees and audit quality by distinguishing among tax, audit-related and other services. We base the analysis on a sample of Spanish listed companies for the period between 2005 and 2016, finding a consistent negative association between future other NAS fees and audit quality. This suggests that the expectation of future purchases of this type of NAS may impair auditor independence. Conversely, for tax and audit-related services results are not significant. Taken together, results suggest that European regulators should seek for further evidence before banning NAS, as some of them may in fact enhance audit quality.     

关于内部审计质量控制的思考

内部审计质量是内部审计工作水平的综合反映和集中体现,加强内部审计质量控制是完善社会主义市场经济的需要。而目前我国在内部审计质量控制方面尚存在着许多的问题,有待我们进一步改善。笔者从影响内部审计质量的各项因素入手,提出几点有利于加强内部审计质量控制的措施。     

The Impact of Consulting Services on Audit Quality: An Experimental Approach

We use experimental markets to examine whether providing consulting services to a non‐audit client impacts audit quality. Our paper directly addresses concerns raised by the Public Company Accounting Oversight Board that the largest public accounting firms’ growth in their consulting practices threatens audit quality. We conduct an experiment proposed using a registration‐based editorial process. We compare a baseline where the auditor does not provide consulting services to conditions where auditors provide consulting to audit clients or where auditors only provide consulting services to non‐audit clients. Our unique design provides evidence on whether providing consulting to non‐audit clients strengthens the salience of a client‐cooperative social norm that reduces audit quality. We do not find differences in audit quality by condition in our planned analysis, however we find greater variation in audit quality in the conditions where auditors provide consulting services compared to the baseline. In unplanned analyses, our results suggest providing consulting services increases auditor cooperation with managers, increasing audit quality when managers prefer high audit quality and decreasing audit quality when managers prefer low audit quality.     

促进自主知识产权发展的国际经验

文章认为,鉴于知识产权在经济发展中的重要作用,很多国家都采取措施发展自主知识产权,主要有：制定实施国家知识产权战略、促进知识产权创造、加强知识产权管理、强化知识产权保护、推进知识产权应用,以及实施知识产权人才战略等。总结这些经验,对我国有重大的启示意义。     

Auditor rotation and the appearance of independence: Evidence from non-professional investors

We examine the impact of audit firm versus partner rotation on non-professional investors’ independence-related perceptions, extending prior research on auditor rotation and independence in fact. Arguments for mandatory audit firm rotation continue to be made by regulators and investor groups based, in part, on the idea that firm rotation will incrementally strengthen independence in appearance relative to audit partner rotation. We report the results of two experiments. The first examines 5-year audit firm versus partner rotation under relatively weak or strong audit committees. We find no statistically significant difference in beliefs about how much of an income reducing audit difference management will record, or in beliefs about auditor independence, between the two auditor rotation conditions. On the other hand, we find that non-professional investors do believe more of the audit difference will be recorded, and the auditors will be more independent, under a strong audit committee than a relatively weak audit committee. The second experiment provides further evidence on audit firm versus partner rotation by examining a setting involving a 26-year audit firm–client relationship. Again, no statistically significant differences between the two auditor rotation conditions were found. These findings suggest that compared to audit partner rotation, audit firm rotation does not strengthen independence in appearance among non-professional investors and that non-professional investors recognize the value of strong audit committees.     

The superiority and disciplining role of independent analysts

We show that although forecasts of independent analysts are less accurate ex post, they yield forecast errors that are more strongly associated with abnormal stock returns. This suggests that forecasts of independent analysts are superior to those of nonindependent analysts in representing ex ante market expectations. We also show that forecasts of nonindependent analysts become more accurate and less biased, and produce forecast errors more strongly associated with abnormal stock returns when independent analysts are following the same firms than when they are not. This suggests that the presence of independent analysts disciplines the behavior of nonindependent analysts.     

管理者特征如何影响企业内部审计外包？——基于中国A股市场调查数据的研究

基于全部A股上市公司的问卷调查数据,探讨管理者特征与企业内部审计外包的关系,结果发现董事长越规避风险、内审负责人的组织认同度越高,企业越可能选择内部审计外包,而总经理的风险偏好、内审负责人年龄对内部审计外包决策影响较弱。进一步的研究表明,董事长风险偏好、内审负责人的组织认同与内部审计外包之间的作用关系主要存在于非国有企业或重视内审职能的企业,仅当企业内部控制较差时,董事长越规避风险,企业越可能外包内部审计,而企业内部控制较好时内审负责人年龄和组织认同更能显著影响外包决策。
