我国上市公司审计委员会有效性检验

抽取我国361家上市公司06年到08年三年的数据组成面板数据,以上市公司审计报告质量和盈余管理水平作为被解释变量来检验审计委员会的有效性。分析结果显示,审计委员会的设立和审计报告质量成正比,和盈余管理水平成反比,表明我国上市公司审计委员会在一定程度上有效。而独立董事比例则与审计委员会有效性成正比,但审计委员会规模与审计委员会有效性成正比的假设没有得到实证的支持。这一结论将为我国上市公司审计委员会未来发展方向提供经验证据。     

对我国现行内部控制评价主体定位的研究

内部控制评价作为企业内部控制的重要组成部分,目前已得到理论界和实务界的广泛关注.然而我国对内部控制评价的研究主要集中在内部控制鉴证方面,忽视了面向管理由内部审计实施的评价,而后者在我国现阶段更为可行,意义尤为重大.本文正是以此为立足点对评价中主体定位问题加以研究.

Is there a glass ceiling for ethnic minorities to enter leadership positions? Evidence from a field experiment with over 12,000 job applications

We conducted a field experiment to analyze if there is a glass ceiling for ethnic minorities entering leadership positions in organizations. We submitted over 12,000 job applications, to over 4,000 job advertisements, to investigate hiring discrimination against six ethnic groups for leadership positions. Drawing on implicit leadership theory, we argue that ethnic discrimination is particularly pronounced in the recruitment of leadership positions. The results confirm this hypothesis. For leadership positions, applicants with English names received 26.8% of positive responses for their job applications, while applicants with non-English names received 11.3% of positive responses. This means ethnic minorities received 57.4% fewer positive responses than applicants with English names for leadership positions despite identical resumes. For non-leadership positions, applicants with English names received 21.2% of positive responses for their job applications, while applicants with non-English names received 11.6% of positive responses. This means ethnic minorities received 45.3% fewer positive responses for non-leadership positions despite identical resumes. Ethnic discrimination for leadership positions was even more pronounced when the advertised job required customer contact. In contrast, hiring discrimination for leadership positions was not significantly influenced by whether the job advertisement emphasized individualism or learning, creativity, and innovation. Our findings provide novel evidence of a glass ceiling for ethnic minorities to enter leadership positions.     

中国审计判断质量的实验研究

近年来,审计质量问题引起了社会的广泛关注,审计判断作为影响审计质量的主要因素之一,日益受到我国审计理论界和实务界的重视。本文以我国注册会计师审计为背景,以内部控制风险评估为案例,采用实验的方法对我国注册会计师的审计判断质量进行了检验。研究结果表明,我国注册会计师的共识、稳定性和自我洞察力已经达到了相当高的水平,但与国外的相似实验研究结果相比,还存在着明显的差距,需要继续提升；在判断过程中,我国注册会计师的判断模型明显呈线性化。     

A Cascaded Inference Model for Evaluation of the Internal Audit Report*

This paper provides a normative framework for how external auditors should evaluate internal audit (IA) work, with a view to assessing the risk of material misstatement. The central issue facing the external auditor when evaluating IA work is the reliability of IA work. Reliability assessments are structured using the cascaded inference framework from behavioral decision theory, in which attributes of source reliability are explicitly modeled and combined using Bayes' rule in order to determine the inferential value of IA work. Results suggest that the inferential value of an IA report is highly sensitive to internal auditor reporting bias, but relatively insensitive to reporting veracity. Veracity refers to internal auditors' propensity to report truthfully, whereas bias refers to the propensity to misreport findings. Results also indicate that this sensitivity to reporting bias is conditional on the level of internal auditor competence, thus suggesting significant interaction effects between the objectivity and competence factors. Collectively, these findings suggest that the impact of source reliability attributes may be more complex than portrayed in the auditing standards and that recognizing these subtleties may lead to greater efficiency and effectiveness.     

中国证券市场审计任期与盈余质量关系的实证检验

安然事件以来,审计任期与盈余(经审计的)质量的关系成为了研究热点.本文运用中国证券市场1998-2004年上市公司的公开数据,同时从事务所任期与合伙人任期两大层面实证检验了审计任期与盈余质量之间的关系.实证结果显示:随着会计师事务所审计任期的增加,盈余质量显著地表现出先逐渐上升后逐渐下降的倒U型趋势,且拐点稳定在6-8年之间;而随着签字注册会计师审计任期的增加,盈余质量虽然总体逐渐上升,但此趋势尚不足够显著.     

Outcomes of Law Teaching in Social Work Education: Further Findings from a Cohort Study

This paper reports further findings from research on the outcomes of teaching law to social work students on UK programmes. This paper compares the results for students on undergraduate and postgraduate routes to an initial social work qualification. It also analyses the similarities and differences in outcomes between the seven universities that participated in the study. Statistical analysis of students' self-audits of their legal knowledge, skills for practising social work law, and their perceptions of the relationship between law and practice, is explored further by drawing on observations from students in focus groups and interviews with their tutors. The differences which emerge between undergraduate and postgraduate students highlight the importance of practice learning opportunities in reinforcing acquired legal knowledge and in developing skills for applying that knowledge in practice. Law teaching can clearly be seen to impact on confidence levels but to be constrained by lack of time and sustained focus throughout the overall curriculum. The similarities of outcome between different universities suggest the impact of particular orientations towards, and an acknowledged core curriculum for, teaching law within the academic curriculum.     

审计委员会与信息披露质量:来自中国上市公司的经验证据

本文选择深交所信息披露考评结果与证券分析师盈余预测精度作为上市公司信息披露质量的衡量指标,使用2006年深市上市公司的相关数据,实证检验了审计委员会与上市公司信息披露质量之间的关系.研究发现,与未设置审计委员会的上市公司相比,设立审计委员会的上市公司具有更高的信息披露质量,审计委员会的独立性对提高上市公司信息披露质量有着积极的促进作用.本文的政策含义是,在进一步完善资本市场的过程中应重视上市公司审计委员会建设.     

公司治理、审计风险与审计定价——基于CCGINK的经验证据

本文采用南开大学公司治理研究中心发表在2004年<管理世界>第二期的论文中公布的2002年度"中国上市公司治理100佳"的公司治理指数作为公司治理质量的替代变量,以"100佳"中的55家2001年至2004年的数据作为研究对象,采用多元回归方法,分析公司治理指数、审计风险、审计师规模与审计定价的关系.结果发现,公司治理指数越高,审计定价越低;随着公司治理指数提高.国际四大和本土五大明显降低了审计定价,而本土次五大的审计定价却没有明显下降,说明审计定价受到公司治理风险影响,国际四大及本土五大对源于公司内部治理的风险更加敏感.原因可能是大型事务所运用了风险导向审计模式,在争取到优质客户后,采取了合理的风险定价策略,以保持优质客户.上述发现对大型审计师获得审计收费声誉溢价的观点做了局部修正.
