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.     

Is there a dark side of competition? Product market competition and auditor-client contracting

This study establishes the informational value of a company's product market competition, derived from qualitative nonfinancial disclosures, in the audit contracting process. Greater product market competition could either serve as means of mitigating agency costs between managers and shareholders or heightening managerial rent-seeking activities and the incentive to distort disclosures. Consequently, greater competition could either increase or decrease audit engagement risk. We find that greater product market competition is associated with greater engagement risk. Auditors respond to the higher risk by assessing greater audit fees. Although auditors respond by charging higher fees and dedicating greater effort to these engagements, we nonetheless find that audit quality is negatively affected by greater competition. Our findings are consistent with the dark side hypothesis of product market competition. Overall, our study provides evidence that company-level competition effects convey valuable information to auditors.     

Market competitiveness and Big 5 pricing: Evidence from China's binary market

Big 5 auditors enjoy a worldwide audit fee premium that is believed to be attributable primarily to their reputation for providing high-quality services to clients. This study finds that the fee premium is also attributable to a lack of competition in the market. Taking advantage of the binary structure of the audit market in China, we compare the pricing practices of the Big 5 in the competitive statutory market and the less competitive supplementary market. Although the Big 5 have a reputation for high-quality audits in both markets, the degree of competition in the two markets is very different. Using audit fee data from the period 2000 to 2003, we find that the Big 5 earn a significant fee premium in the less competitive supplementary market, but not in the competitive statutory market. Although our results do not completely rule out reputation as an explanation, they are consistent with the notion that the audit fee premium that is earned by the Big 5 is more likely to be attributable to their dominant market position than to their reputation in the emerging Chinese markets, in which the usual audit-quality benefits for investors and managers are either absent or minimal.     

会计师事务所的属性重要性与审计收费——基于中国会计师事务所综合评价前百家信息的证据

审计收费是对事务所的审计师团队努力的回报,而审计师团队有多种不同重要程度的属性,因此有必要把会计事务所作为一个拥有多个属性重要性的系统,具体考察其对于审计收费的影响。本文根据中国注册会计师协会年度会计师事务所综合评价前百家信息,具体考察了会计事务所的属性重要性对审计收费的影响。研究表明,事务所中的CPA的教育结构、CPA的经验(年龄)结构和事务所综合规模对审计收费具有显著正向影响。事务所其他属性与审计收费未发现存在显著相关性。     

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.     

An examination of the relation between market structure and the profitability of audit engagements

Due to increasing supplier concentration, there is growing concern regarding the lack of competition in the audit market. Theory based on Cournot oligopoly predicts that increasing concentration will facilitate monopolistic behaviour. Conversely, if the market for audit services has more in common with a Bertrand oligopoly, concentration may not lead to higher fees. We evaluate whether increased audit supplier concentration leads to economic rents by investigating audit profitability. Using proprietary data from a (then) Big 6 audit firm, we find that local market structure has a significant and positive association with audit profitability, but not auditor effort for large clients.     

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.     

The CLERP 9 Audit Reforms: Benefits and Costs Through the Eyes of Regulators,Standard Setters and Audit Service Suppliers

Over the past decade or more Australia amongst other jurisdictions has experienced substantial reforms to auditing regulation in an effort to boost public confidence in the auditing profession. This paper aims to examine whether these changes in the Australian regulatory environment for audits have (a) provided enhanced confidence in reported financial data, (b) impacted audit costs and (c) not limited competition in the market for audit services. Using qualitative interview data, this study reports on the perceptions of auditors, auditing standard setters and regulators in relation to the CLERP 9 reforms to the Australian auditing regime in the later part of the 2000s. A theoretical framework is developed to evaluate whether these reforms are substantive enough in nature to effect public confidence in reported financial data and market competition in audits.     

Note on audit fee premiums to client size and industry specialization

This research note examines the impact of client size on the estimation of audit fee premiums in the Australian market for audit services. Previous research suggests that higher audit fees are expected for both larger clients and for industry specialization. We find that in the Australian market for audit services, the fee premium attributed to industry specialist audit firms is concentrated in the audit fees paid by the largest clients in each industry. One reason for higher fees paid by larger clients is the demand for additional audit services. We find higher fees for companies cross‐listed on US exchanges. We also find that fee premiums to auditors that are city‐industry leaders are strongly related to client size.     

Adjustment costs of institutional tax changes from the audit pricing perspective: Empirical evidence from the VAT reform

Institutional changes inevitably impose adjustment costs on firms while also generating benefits. However, empirical evidence regarding the adjustment costs of institutional changes is limited, with much of the focus centered on benefits. Using data on China’s A-share listed companies from 2010 to 2018 and the nation’s staggered adoption of the “business tax to value-added tax reform” (hereafter, “VAT reform”) as a natural experiment, we examine the impact of this reform on a particular corporate cost: audit fees. We find audit fees to be 8.11% higher for VAT reform firms than for non-VAT reform firms. This difference does not exist before or after the reform year. That is, it is only observed in the year of VAT reform implementation. This indicates the existence of an adjustment cost specifically related to the VAT reform. Furthermore, we observe larger fee increases among firms audited by Big 4 international audit firms, firms that require more audit work, firms that are more complex, and firms with weak internal controls. From the audit pricing perspective, we provide evidence of the economic consequences of tax reform. The corporate adjustment costs that arise from institutional changes deserve more attention from decision-makers.     

Audit report lag: the role of auditor type and increased competition in the audit market

This study investigates the effect of auditor type (private vs. state) and increased competition in an audit market on audit report lag (ARL). This is the first study to provide evidence regarding the effect of audit market competition on ARL. Utilising structure–conduct–performance theory, we predict that competition pressures private auditors to be more efficient and to have less reporting lag than state auditors. We also predict that competition among auditors after a liberalisation period forces auditors to be more efficient and to record less ARL than before. We use a unique data set in Iran, whereby the audit market liberalisation (an audit market where services were previously provided primarily by a state entity) has resulted in both state and private auditors simultaneously providing audit services. The findings are consistent with the following hypothesis, that is ARL is shorter for private auditors than it is for state auditors, and ARL decreases as competition increases in the Iranian audit market. Consistent with the structure–conduct–performance theory, the findings suggest that increased competition in the audit market results in higher efficiency, as reflected by a shorter ARL.     

Employee quality and audit fee: evidence from China

This study investigates the association between employee quality and audit fee. Using data for firm-level employee quality (as proxied by employee education) from Chinese listed firms from 2011 to 2018, we find that firms operated by high-quality employees enjoy lower audit charges. The association between employee quality and audit fee is more pronounced in firms with a culture of high integrity. Our 2SLS estimation helps us establish a causal link between employee quality and audit fee. The final validity tests suggest that high-quality employees contribute to lower audit fee by reducing audit risk and audit effort.     

Transaction costs and competition among audit firms in local markets

We develop a measure to capture an audit firm's competitive position in a local audit market based on the transaction costs of changing audit firms included in DeAngelo's (1981) multi-period audit pricing model. Our competition measure reflects the size difference between the largest audit firm in a market specified by client industry at the city level and the other audit firms operating in that market. We find that audit fees of a client decrease as this size difference increases. This result suggests that smaller audit firms charge lower audit fees because of their competitive disadvantage to the local largest firm.     

How audit effort affects audit quality: An audit process and audit output perspective

Using a unique dataset of audit days in China from 2006 to 2011, this paper examines the relationship between audit effort and audit quality from the perspective of audit process and audit output. The results show that audit effort significantly increases the probability of audit adjustments, which inhibits positive earnings management and improves the quality of audited financial statements. We also find that audit effort does not have a significant effect on the issuance of modified audit opinions overall, but that a modified audit opinion is more likely to be issued in the absence of an audit adjustment. Furthermore, we find that the impact of audit effort on audit quality is attenuated when clients are more complex and when audit firms are larger. Collectively, our evidence suggests that audit effort plays an important role in improving audit quality by influencing audit process and audit output. Our study extends the literature on the impact of audit effort on audit quality in emerging markets, and the conclusions have important implications for the improvement of China’s audit market efficiency.     

The effect of small audit firms’ failure to remediate the PCAOB’s quality control criticisms on audit market segmentation

This paper examines the role of the Public Company Accounting Oversight Board (PCAOB) quality control inspection program on market segmentation of small firms’ audit services. Specifically, we investigate how non-remediation of quality control criticisms (QCCs) affects the supply and demand of low-quality audits. We find that remediation of QCCs improves audit quality for small accounting firms. However, some small accounting firms do not remediate QCCs (NR firms) and continue to provide low audit quality. We investigate how NR clients react to the disclosure of non-remediation of QCCs. We find that NR clients with low agency costs are more likely to retain NR firms after the disclosure of non-remediation. This finding is consistent with our expectation that voluntary QCC remediation creates a low-quality audit market segment for NR firms. Our findings suggest that the public disclosure of QCCs is not sufficient to remove low-quality auditors. Instead, NR clients use the disclosure of non-remediation of QCCs as a signal to sort themselves into segments based on their demand for audit quality. We are the first to study and find that PCAOB inspections, and specifically the voluntary nature of remediation and public disclosure of lack of remediation, create market segmentation.     

The Pricing of Audit Services: Further Evidence from the Canadian Market

Since the seminal work of Simunic (1980), many studies have investigated audit pricing, competition in the audit industry, product differentiation and audit cost functions. This study expands on the work done to date by examining Canadian audit fees across time, audit firm and industry. The observations of audit fee data span the period of time during which the provincial codes of professional ethics with respect to fee tenders and advertising in general were relaxing in Canada. The results reported in this study support the existence of differentiated audit services in the Canadian audit market, and are consistent with DeAngelo's (1981) size interpretation of audit quality. Although no significant differences in the pricing of audit services across time are detected, the data provide evidence of significant pricing differences across (pre-merger) Big Eight audit firms in the small auditee market, suggesting that treating these audit firms as a homogeneous group in future research may not be appropriate. These inter-firm pricing differences do not appear to be due to the potential confounding effects of the auditee's industry. In contrast to previous studies, a significant positive association between internal and external audit costs is observed, suggesting a complementary, rather than a substitute, relationship.     

The effect of audit firm size on audit prices: A study of the Australian Market

The effect of audit firm size on prizes is a complex function of competition in the market for audit services, product differentiation, and scale economics to large firms. In this study, a competitive market is supported in Australia with product differentiation to Bif Eight accounting firms. Specially, Big Eight accounting firms have significantly higher audit prices than non-Big Eight firms. This results holds for ‘large’ and ‘small’ auditees. A test is also made of price cutting in the Australian market. Price cutting is defined as lower initial audit fees than continuing engagement fees for a comparable audit. Test results do not evidence price-cutting behavior by accounting firms. There is in fact weak evidence that initial audit fees are higher than continuing engagement fee levels. Higher initial fees suggest that accounting firms may recover at least some of the audit start-up costs immediately.     

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.     

Audit effort and fees under concentrated client ownership: Evidence from four international audit firms

Using proprietary audit hour and fee data from the internal records of four Big Six firms in Finland, this study examines the influence of audit client ownership type on audit effort and fees. The primary argument is that there are differential effects of ownership concentration depending on the particular nature of concentrated ownership (i.e., firms in which the majority of shares are manager-owned versus foreign-owned versus state-owned). Consistent with this, the paper documents that audit hours and fees are lower for companies majority-owned by their management and higher for subsidiaries of foreign companies than for other firms. However, no difference between companies owned by the state or municipalities and companies with a more diverse ownership structure can be found. This suggests that governmental ownership is actually closer to a dispersed than a concentrated ownership structure in terms of audit quality.The results show that replacing the variable indicating majority-ownership with the variables capturing the type of a controlling owner increases the explanatory power of the models significantly, which demonstrates the importance of ownership type in the production and pricing of an audit. The findings have important implications for those examining audit markets with client firms owned by different types of controlling shareholders.     

Agency problems and audit fees: further tests of the free cash flow hypothesis

This study finds that the agency problems of companies with high free cash flow (FCF) and low growth opportunities induce auditors of companies in the US to raise audit fees to compensate for the additional effort. We also find that high FCF companies with high growth prospects have higher audit fees. In both cases, higher debt levels moderate the increased fees, consistent with the role of debt as a monitoring mechanism. Other mechanisms to mitigate the agency costs of FCF such as dividend payout and share repurchase (not studied earlier) do not moderate the higher audit fees.
