人民币汇率变动的物价传递效应:多结构变化协整回归分析

现有研究物价传递效应的文献以线性模型为主,甚少关注物价传递过程中可能存在的结构变化,本文在充分考虑我国转轨时期所面临的各种经济冲击的条件下,利用最新发展的多结构变化协整回归方法考察了1994年1月至2008年12月间人民币汇率变动的物价传递效应。研究结果表明,人民币汇率变动的物价传递效应分别在1998年8月、2002年10月、2005年8月及2007年7月发生了四次结构变化,传递效应虽总体趋减,但2007年7月后出现了反复,且符号也发生了改变。在上述结论基础上,本文提出了相关政策建议。     

大股东资金占用与审计师的监督

本文研究审计师对大股东占用上市公司资金行为的监督作用。通过对1997年到2002年间的上市公司进行分析,我们发现随着大股东资金占用程度的加大,审计师更加倾向于出示非标准意见。在大股东占用资金最多的10%的公司年度中,审计师出示非标准意见的概率高达近50%。在控制了其他影响审计师意见的变量以后,大股东资金占用程度仍然是决定审计意见的一个非常显著的因素。这说明我国的审计师对中国资本市场出现的大股东资金占用问题有一定的认识,并且将其反映到审计师意见中去。我们进一步的分析发现: (1)被审计师出具了非标准意见的公司,其大股东占用资金反而更加持续。这说明审计师意见对公司的监督意义不大,公司并没有因为审计师的意见而减轻占用程度。(2)被审计师出具了非标准意见的公司,其大股东占用对未来的股票收益的负影响与其他公司并没有区别。这说明投资者对审计师的意见并没有给予足够的重视。本文的研究结果说明,审计师对大股东盘剥中小股东的现象进行了监督、对大股东资金占用严重的公司出示了更多的非标准意见,然而这些非标准意见并没有引起各方面的重视,一方面公司的治理并没有改善,另一方面投资者也没有因审计师的意见而避免更多的损失。     

Audit Firm Tenure and Audit Quality in a Constrained Market

We examine the relation between audit quality and audit firm tenure in the Iranian audit market, which is constrained by government policies that create intense competition for clients among many small audit firms. We develop arguments that these circumstances create cost pressures that entrench low audit quality and render auditors' plans more predictable to managers wishing to misstate their accounts. Using publicly available data for the audits of listed companies in Iran prior to mandatory audit firm rotation and the incidence of misstated financial reports identified by the Iranian Association of Certified Public Accountants Inspection Office, we find that the likelihood of a misstatement is lowest in the first two years of audit firm tenure. We also find that the likelihood of misstatement is not associated with the year preceding a mandatory audit firm rotation, suggesting outgoing auditor effort is not sensitive to the prospect of subsequent revelations of deficiencies. Although our results from a pre-mandatory rotation period show that frequent rotations appear to improve the financial reporting quality in our sample, we are wary of interpreting these results as support for the mandatory audit firm rotation policy in Iran. Rather, we suggest this is a peculiar consequence of deficiencies in audit quality inherent in the Iranian market.     

Audit report information content and the provision of non-audit services: Evidence from Spanish lending decisions

This study examines whether auditor economic independence affects the information content of going concern audit reports in the European setting. We conduct an experiment where 80 experienced Spanish loan officers from the second largest European commercial bank review a loan request under two lending scenarios: (1) a potential borrower receiving an unqualified but modified going concern opinion, and (2) a potential borrower receiving a qualified going concern opinion. Auditor economic independence, measured by the provision of non-audit services (NAS), is manipulated (absence vs. presence of significant NAS). We find that a qualified going concern audit report is interpreted as a primary warning signal (death penalty). However, the provision of NAS acts as a second order mechanism that only activates loan officers’ professional skepticism in the case of an unqualified but modified going concern report scenario. Therefore, we find evidence suggesting that the potential negative impact of a perceived lack of auditor independence depends on the nature of the audit report. Our findings have important implications for the European regulator, which is currently considering establishing an auditor independence regulation framework similar to that in the United States of America.     

Is the quality of female auditors really better? Evidence based on the Chinese A-share market

Unlike previous studies in which a single index was used to measure audit quality, this study establishes a new comprehensive index to measure audit quality via Discretionary Accrual, as estimated by Jones’ basic model (1991) and Audit Opinions. The former is used to measure the quality of financial statements, and the latter is used to measure the auditors’ independence in the mainstream international literature. We examine whether and how an auditor’s gender affects the quality of his or her audits under the framework of empathy theory and gender role socialization theory. Using a large sample of 9861 auditor-firm-year observations from Chinese A-share–listed companies from 2011 to 2015, we find that the audit quality of signed auditors shows significant gender differences: these significant gender differences differ from the findings of previous studies that female auditors could provide a higher-quality audit than male auditors; that is, in our study the audit quality of the male auditors exceeds that of the female auditors. After distinguishing the positive and negative directions of the Discretionary Accrual, we find no significant gender differences in audit quality between male and female auditors when the earnings had been adjusted upward by the client; that is, female and male auditors had the same audit risk perception. However, when the client adjusted earnings downward, which indicates a lower audit risk for the auditor, the audit quality of female auditors was significantly lower than that of the male auditors. After controlling for the age and position of the auditors, we also find that the gender differences in the auditors’ audit quality decreased significantly or even disappeared when the auditor’s age exceeded 45?years and/or their position was manager or above. These results are consistent with the empathy theory and gender role socialization theory.     

CFO审计师经历、旋转门现象与会计稳健性

到客户管理层就职是会计师事务所审计师的一个重要职业选择,但监管机构对审计质量和企业财务报告质量的担忧引发了对此类现象的严格监管.本文基于2002年~2011年我国A股上市公司CFO的变更事件,从审计师的职业谨慎性出发,探讨了CFO审计师经历、"旋转门"现象对上市公司会计稳健性的影响.研究发现:CFO审计师经历能提高会计稳健性;"旋转门"现象并没有削弱公司会计稳健性;相比仅有审计师经历的新聘任CFO,"旋转门"现象下的CFO能更快地融入新公司并发挥作用.     

Corporate governance,accounting and finance: A review

We review accounting and finance research on corporate governance (CG). In the course of our review, we focus on a particularly vexing issue, namely endogeneity in the relationships between CG and other matters of concern to accounting and finance scholars, and suggest ways to deal with it. Given the advent of large commercial CG databases, we also stress the importance of how CG is measured and in particular, the construction of CG indices, which should be sensitive to local institutional arrangements, and the need to capture both internal and external aspects of governance. The ‘stickiness’ of CG characteristics provides an additional challenge to CG scholars. Better theory is required, for example, to explain whether various CG practices substitute for each other or are complements. While a multidisciplinary approach to developing better theory is never without its difficulties, it could enrich the current body of knowledge in CG. Despite the vastness of the existing CG literature, these issues do suggest a number of avenues for future research.
