董事会与独立审计的关系:补充抑或替代

本文采用我国A股上市公司2001-2003年度相关数据,通过面板统计模型,分析董事会特征对审计定价的影响,借此考察我国上市公司董事会与独立审计的关系.研究结果表明:董事会规模、董事会勤勉性未对审计定价产生显著影响,董事会独立性对审计定价存在显著负向影响,这意味着我国上市公司董事会与独立审计之间存在替代关系而非补充关系.     

企业金融化、内部控制与审计定价

以2007-2018年我国A股非金融类上市公司为研究对象,探讨并实证检验企业金融化、内部控制与审计定价之间的关系.研究表明:企业金融化与审计定价正相关,内部控制在企业金融化与审计定价之间的正相关关系中发挥负向的调节作用;企业金融化主要是通过影响审计业务复杂度进而影响审计定价;企业金融化对审计定价的正向影响在企业规模越大、受融资约束越高、内部控制缺陷越严重的企业更显著.     

上市公司董事会规模与构成的影响因素

本文选取2005年中国证券市场的相关数据,对上市公司董事会规模与独立性的影响因素进行了系统的理论和实证分析,研究结果表明,我国上市公司的董事会规模和独立性受到公司经营范围与复杂性、监管成本收益关系和讨价还价等因素的影响.     

审计委员会治理与审计意见

本文从审计委员会的存在性、独立性和勤勉程度三个方面,将审计委员会与审计师规模、异常审计收费、审计师变更等结合起来考虑,探讨审计委员会治理对上市公司年报审计意见类型以及不利审计意见改善和审计意见恶化的影响。研究表明,相对于审计委员会的存在性,审计委员会的独立性和勤勉程度对外部独立审计师审计判断及其所出具的审计意见的影响更为显著;在结合考虑审计师规模、审计收费、审计师变更等相关因素的前后均可以发现,在董事会中设立审计委员会并切实提高审计委员会的独立性和勤勉程度,不仅有助于提升上市公司财务报告的质量,而且亦有助于在一定程度上对管理层的审计意见购买行为进行有效的制衡。     

董事会特征、资产质量与审计收费研究

本文利用我国2001-2003年上市公司数据,实证研究了董事会特征、资产质量与审计收费的关系。研究发现,总体上看,上市公司资产质量越差,董事会越独立,审计收费越低。而董事会越勤勉,审计收费越高,董事会规模与审计收费没有呈现相关性。同时,会计事务所会综合考虑公司资产质量与董事会特征,表现在对资产质量越差,董事会越勤勉的公司收费越高。同时也发现,“四大”与非“四大”会计事务所审计费用影响因素存在显著差异。     

中国审计定价实证研究述评

审计定价一直是审计市场研究的热点问题之一。本文围绕着政策制定者所关注的四个问题,即审计定价的决定因素、低价揽客、盈余管理、事务所规模以及品牌与审计定价之间的关系,回顾了我国对审计定价研究的经验证据,指出目前实证研究结论的分歧之处,然后总结这些证据的研究启示,最后指出未来该领域的研究方向。     

上市公司董事会特征与审计质量的实证分析—以山东省济南市上市公司为例

济南市上市公司董事会特征与审计质量存在一定程度的相关性,如董事会规模、独立董事比例、董事薪酬与审计质量显著正相关等;董事长与总经理兼任情况与审计质量呈显著负相关;董事会会议次数、四委会设立比例与审计质量有不显著正相关关系。本文在实证分析的基础上。提出建议措施,对提高济南市上市公司的审计质量有一定使用价值。

中国上市公司初始审计的定价折扣考察——来自审计师变更的经验证据

初始审计的定价折扣具有重要的与审计独立性相关的公共政策含义。本文基于DeAngelo(1981)和Dye(1991)关于初始审计定价折扣的竞争性理论预期,利用2002——2004年我国审计市场的数据对初始审计的定价行为与特征进行了较为细致的实证考察。经验结果支持中国证监会关于审计费用的强制性公开披露政策,准租金和低价折扣引起的潜在的审计独立性问题会随着审计费用的公开披露而得到消除或减轻。本文还具有重要的监管含义:对审计师变更的监管应着重关注那些大型上市公司在小型会计师事务所之间进行变更的行为。     

审计委员会与外部审计独立性

本文首先从完全信息动态博弈的视角出发,推导得出,强化外部审计独立性是审计委员会的基本职能之一.然而,接下来的实证检验结果却与前述的理论预期相悖,即实证检验结果表明,我国上市公司审计委员会制度在实际运行中,并不具有强化外部审计独立性的功能.接下来的分析表明,由于缺乏"独立人"的资格,导致我国审计委员会很难打破原有的均衡,从而很难强化外部审计独立性.     

An empirical analysis of audit fee price competition after the Korean 1999 Omnibus Cartel Repeal Act

This study examines the audit service market in Korea after the 1999 Omnibus Cartel Repeal Act to determine if increased competition has led to audit fee discounting. Until 19 December 2001, when the Korean government enacted The Financial Supervisory Regulations, researchers could not address questions related to price competition in the Korean audit market due to data limitations. The new regulations allow researchers to examine audit effort for the first time because both audit hours and audit fees are now recommended disclosures. We use audit fee data of Korean companies for the 6-year period 1999–2004, and find evidence that total audit fees paid have been increasing but audit fees per hour have been decreasing. We also find that Big 5 auditing firms’ fees per hour are significantly lower than non-Big 5 auditing firms and are decreasing across time. These price pressures should be of concern to regulators and investors because prior research has demonstrated that price competition leads to discounting, which can result in unrealistically low audit fees and poor audit quality. Finally, as in previous research, we also find discounting of initial audit engagements in the Korean market.     

The impact of customer firm data breaches on the audit fees of their suppliers

This study investigates whether audit risks that accompany data breaches of major customer firms can spillover into the supply chain and affect audit fees of their suppliers. Based on the economic bond that exists between supplier firms and their major customers, we predict that data breach incidents of customer firms will lead to higher audit fees for their respective suppliers. Consistent with customer breaches increasing the audit risk to the supplier, we observe a positive association between breach disclosures made by major customers and audit fees of the supplier firm. This association exists for both internal and external data breaches. We further find that audit fees are increasing with the number of major customers disclosing a breach in a given year. Our results are robust to both a matched sample design and a difference-in-difference approach. Interestingly, we find that while supplier auditors appear to price the risks associated with customer breaches, the breaches do not appear to affect audit quality. The findings of this study are timely and relevant to academics, practitioners, and regulators as supply chains continue to become larger and more complex.     

Determinants of audit fees in Bangladesh

This paper reports the results of an analysis of the determinants of audit fees of both financial and non-financial companies in Bangladesh. The Bangladeshi audit services market is unusual in that there is no direct involvement of international audit firms in it. The results of the regressions show that the size of the auditee has the greatest influence on audit fees. Whilst there was no international Big Six grouping, it was possible to construct a group of Bangladeshi audit firms which commanded a price premium, based on their size and whether they had a link with an international firm of auditors. Financial services companies were found to have higher audit fees relative to non-financial companies. Subsidiaries of multi-national holding companies also had higher audit fees. The surprising result was that auditees which employed at least one qualified accountant had higher audit fees.

Audit Firm Ranking,Audit Quality and Audit Fees: Examining Conflicting Price Discrimination Views

In this study, we examine whether highly ranked audit firms in Iran, as determined by the Securities and Exchange Organization (SEO), earn a fee premium, firstly, by providing superior quality audit services or, secondly, due to reputation created by the ranking system implemented by the SEO. We employ price discrimination theory, and we test quality discrimination versus brand reputation explanations in the context of a unique institutional setting (where international audit firms are not allowed to operate). The data are derived from firms listed on the Tehran Stock Exchange (TSE) for the period 2006 to 2015. Our results show that the quality of audit services (using all of our measures) provided by the highest ranked audit firms is not superior to that of the non-highest ranked firms. In addition, the audit fee models suggest that the highest ranked firms charge significantly more audit fees compared to lower ranked firms. We employ several sensitivity tests and the results do not change materially. Such findings go against the “quality-based price discrimination” view but support the reputation-based view, and make a significant contribution towards understanding the economic consequences of state-determined ranking of audit firms rather than allowing the market to determine quality differentiation.     

Relation between external audit fees, audit committee characteristics and internal audit

This study examines whether the existence of an audit committee, audit committee characteristics and the use of internal audit are associated with higher external audit fees. Higher audit fees imply increased audit testing and higher audit quality. We find that the existence of an audit committee, more frequent committee meetings and increased use of internal audit are related to higher audit fees. The expertise of audit committee members is associated with higher audit fees when meeting frequency and independence are low. These findings are consistent with an increased demand for higher quality auditing by audit committees, and by firms that make greater use of internal audit.     

不利意见、审计费用与意见购买

本文进一步区分上年度不利审计意见的具体类型、审计费用的升降以及审计意见的改善与恶化。研究证实:(1)上年度被出具不利审计意见虽然可能增加本年度收到不利审计意见的可能性,但是亦可能提高审计意见改善的可能性,并和审计意见出现恶化的可能性显著负相关。(2)如果上年度被出具不利审计意见,则异常审计费用与审计意见改善的可能性显著正相关。(3)审计费用的增加能显著降低被出具不利审计意见的可能性,并可有效防止年报审计意见出现恶化。可见,公司管理层可以通过提高审计费用成功地实现审计意见购买动机,在一定程度上规避不利审计意见。     

Pricing and supplier concentration in the private client segment of the audit market: Market power or competition?

This study differs from prior audit-pricing studies as (1) it focuses on the issue of price competition in the (small) private client segment of the audit market and (2) addresses the questions of whether and how the audit-pricing model changed in that market between 1989 and 1997. Given the significant increases in market concentration and two big audit firm mergers in that period, we try to assess whether price competition (market power) has increased (decreased) or decreased (increased). We use Belgian data on privately owned companies from 1989 and 1997 for our analyses. We find that audit fees are significantly associated with the incumbent auditor's market share both in 1989 and 1997. Our results are in line with prior studies on public client samples and hence do not support prior assumptions that there are no price premia charged by large auditors in the small client segment of the audit market. As to the evolution of audit pricing in the private client segment of the Belgian audit market between 1989 and 1997, we find that the impact of various audit fee determinants changed significantly and report evidence supportive of increased price competition.     

Audit firm tenure and financial restatements: An analysis of industry specialization and fee effects

This study investigates the relation between audit firm tenure and clients’ financial restatements. Specifically, we extend the audit tenure literature by assessing restatement-based reporting failures using dimensions of auditor expertise and independence previously assumed to underlie short and long audit tenure problems. Short tenure expertise and independence effects are hypothesized using audit firm industry specialization and audit fees as proxies. Long tenure independence effects are hypothesized using nonaudit fees as a proxy. Using matched-sample logistic regression and 382 companies with and without financial restatements during 2000–2004, the results support prior findings by indicating a negative relation between the length of the auditor–client relationship and the likelihood of restatement. For short tenure engagements, we find that auditor industry specialization and audit fees are negatively related to the likelihood of restatement. This result is consistent with concerns about reduced audit quality due to a lack of client-specific knowledge and low audit fees on new audit engagements. Alternatively, the long tenure results indicate an insignificant relation between nonaudit fees and the likelihood of restatement. This finding contradicts independence concerns about nonaudit fees paid to entrenched auditors.     

Independent audit committee members’ board tenure and audit fees

An independent audit committee is an audit committee on which all members are independent directors. This study examines whether independent audit committee members’ board tenure affects audit fees. On the basis of the prior literature, we formulate an unsigned hypothesis. This is because on the one hand, long board tenure audit committee members (defined as members with board tenure of 10 or more years) have greater incentives to protect their reputational capitals by purchasing increased audit effort, which positively affects audit fees. On the other hand, audit pricing reflects audit committee quality. Long board tenure audit committee members may have less need for increased audit effort because they can effectively oversee the financial reporting process themselves, which negatively affects audit fees. We find that audit fees are negatively associated with the proportion of long board tenure directors on the independent audit committee, consistent with the notion that audit committee members’ long board tenure results in lower audit effort.
