Auditor Market Share,Product Differentiation and Audit Fees

This study examines the effects of auditor market share and product differentiation on audit fees. Previous studies have attributed the price premium charged by the Big Eight (the Big Six in the present study) to Big Eight product differentiation. However, such a price premium could be partly due to monopoly pricing. In the present study, the Hong Kong audit market provides a unique setting in which a non-Big Six local auditor has a market share comparable to those of the third and fourth largest Big Six firms. This makes it feasible to control for the effects of market share via matching. Also, the wide disparity among the Big Six firms ‘market shares in Hong Kong makes it feasible to test for the effects of market power on audit fees. The results show that, consistent with prior studies, the Big Six audit firms charge higher audit fees than non-Big Six firms in the small auditee, but not the big auditee, market. This suggests that similar economic forces to those other audit markets are also at work in Hong Kong. Despite the Big Six firms’ widely different market shares, there was no price differentiation among them. Yet there was a Big Six price premium over the large local firm with a similar market share to those of two of the Big Six. Together, these results suggest that the Big Six price premium is a result of product differentiation rather than monopoly pricing.     

The effect of large audit firm mergers on audit pricing in the UK

This paper examines the effects on UK audit market concentration and pricing of mergers between the large audit firms and the demise of Andersen. Based on data over the period 1985–2002, it appears that mergers contributed to a rise in concentration ratios to levels that suggest concern about the potential for monopoly pricing. The high concentration ratios have not improved the level of price competition in the UK audit market. Our pooled models suggest that concentration ratios are associated with higher audit fees. The evidence suggests that the effects of mergers between big firms on brand name fee premium and on price competition vary depending on the particular circumstances. The brand name premium is strongest for the largest quartile of companies prior to the mergers. After the Big Six mergers, the premium increases for average‐sized companies but falls for the smallest and largest companies. Following the PricewaterhouseCoopers merger, the premium increases for below median‐sized clients but decreases for above‐median sized clients. For the Deloitte‐Andersen transaction, the premium falls for the smallest and largest companies but increases for those in the second quartile. Our results provide evidence that auditees are likely to pay higher fees if their auditor merges with a larger counterpart. We attribute merger‐related fee hikes to product differentiation, rather than anti‐competitive pricing.     

Independent and joint effects of audit partner tenure and non-audit fees on audit quality

We examine the individual and joint effects of auditors’ non-audit services (NAS)/abnormal NAS fees and length of audit partner tenure on audit quality. Our results raise questions about the ‘one size fits all’ approach imposed by the current audit partner rotation requirement in Australia as a result of (1) a learning differentiation that we observe between Big 4 and non-Big 4 auditors and (2) higher discretionary accruals associated with non-Big 4 auditors. We find abnormal NAS fees to have a positive association with both absolute and positive (income-increasing) values of discretionary accruals for firms with short audit partner tenure. NAS/abnormal NAS fees are also negatively associated with the issuance of going concern opinions to financially distressed firms when partner tenure is short. In terms of policy implications, regulators are able to gauge the efficacy of the CLERP 9 reforms which currently impose a five year mandatory audit partner rotation requirement.     

The reform of accounting standards and audit pricing

This paper focuses on the reform of accounting standards in China in 2007 and investigates its impact on equilibrium pricing in the audit market. We find that the concentration of the audit market and the probability of issuing modified audit opinions do not significantly change, but that audit fees increase significantly after the adoption of the new accounting standards in China. Deeper analysis suggests that (1) the implementation of the new IFRS-based Chinese Accounting Standards (CASs) has increased the market risk faced by listed firms and thus auditors’ expected audit risk, causing an increase in audit fees, and (2) the degree of the increase in audit fees is positively related to the adjusted difference between net income according to the old CAS before 2007 and the new CAS after 2007. We thus conclude that the reform has had a significant impact on audit pricing in China.     

Local creative culture and audit fees

This paper examines the association between local creative culture and audit fees. Using a large, unbalanced panel data of listed US firms between 2004 and 2018, we find evidence that firms headquartered in US counties with high creative culture tend to pay higher audit fees than firms headquartered in counties with low creative culture. We also find that such firms tend to have longer audit report lag and are subject to more shareholder litigation. Cross-sectional tests show that real earnings management, managerial risk-taking propensity, and external corporate governance environment moderate the positive association between creative culture and audit fees. The positive association between local creative culture and audit fees remains robust to controlling for endogeneity concerns. Our study contributes to the emerging literature on local creative culture by providing evidence that local creative culture encourages managers and employees to undertake risky initiatives, thereby increasing audit risks.     

Audit firm merger and the strategic response by large audit firms

We examine the impact of a change in the audit industry structure in China as a result of two recent mergers involving large non-Big 4 audit firms. The ‘New Big’ audit firms, Ruihua and BDO Lixin, became the third and fourth largest audit firms in China following audit firm mergers, outranking both EY and KPMG in terms of total audit revenues in 2013. We find a significant audit fee and audit quality increase for the New Big audit firms relative to the Big 4 audit firms following the mergers. While this finding could be interpreted as an increase in quality as a result of audit firm consolidation, we find that this net effect is due to a decrease in audit fees and audit quality for the Big 4 following the mergers, rather than an increase in audit fees and audit quality by the New Big audit firms. We discuss the implications of our findings for various regulators.     

The Effect of IPO Risks on Auditors’ Decisions: Auditor Designation Case

This study examines the effect of audit risks in the Korean initial public offering (IPO) market on the designated auditors’ decisions. The Korean External Audit Act requires firms to switch from incumbent to new auditors designated by the Securities and Futures Commission after the firm announces a future IPO. This study shows the effects of audit risks by examining if the quality of reported earnings and audit fees significantly differs between IPO‐eligible and IPO‐ineligible firms. Empirical tests first show that discretionary accruals are significantly lower for IPO‐ineligible firms than for IPO‐eligible firms in both the IPO designation period and the following review period. We interpret this result to mean that designated auditors evaluate the IPO‐ineligible (and eventually failed) firms’ listing possibility as low. Second, audit fees are higher for IPO‐ineligible firms in the auditor designation period. This reflects the fact that designated auditors are exposed to future audit risks associated with firms’ post‐IPO financial market troubles if IPO‐ineligible firms attempt to go public. Our study contributes to IPO‐related research by showing the effects of auditors’ risk evaluation on discretionary accruals and audit fees. This study also contributes to accounting policymaking regarding auditor independence.     

CFO narcissism and audit fees: Evidence from listed companies in China

This paper examines the effects of CFO narcissism on audit fees in China. Using the size of CFO signatures in annual audit reports to measure individual narcissism, we find that CFO narcissism is associated with higher audit fees. We find empirical evidence that CFO narcissism significantly increases the audit fees of listed companies, and this effect is stronger in state-owned enterprises. This paper also explores the mediating effects of financial information and the engagement of prestigious Big-4 and Big-10 firms. The results show that companies with narcissistic CFOs have lower quality financial information and prefer more prestigious firms, which leads to higher audit fees. This research highlights the importance of CFO narcissism in corporate performance and provides new evidence that will be useful for listed companies that plan to hire senior executives.     

Workforce environment and audit fees: International evidence

Using a dataset from 30 countries over the period from 2002 to 2017, we examine the effects of auditing clients’ workforce environment on audit fees as well as the role that national labor market flexibility plays in this relationship. We find evidence that audit fees are significantly lower for firms with a good workforce environment, suggesting that auditors perceive such clients as less risky; as a result, auditors expend less effort and/or charge a lower risk premium. Furthermore, we find this effect to be stronger for firms in countries with a more flexible labor market. Our mediation test results indicate that the relationship between the audit client workforce environment and audit fees is mediated by media coverage of workforce controversies. Our study contributes to the international audit fee literature by identifying employee welfare as a distinct audit pricing factor, above and beyond the effects of overall corporate social responsibility practices.     

Audit fee lowballing: Determinants,recovery, and future audit quality

Prior research on the link between lowballing (LB) of audit fees and audit quality is inconclusive. Using more recent data and an innovative design, we define LB engagements as those where the audit fee discount is at least 30 percent. We consider three research questions to understand the possible link between LB and audit quality. First, we investigate whether the two variables that are often associated with auditor independence in the literature—non-audit fees and client importance—are related to LB. Second, we test whether lowballing auditors recoup initial audit fee discounts in the future period. Lastly, we investigate the relation between recovery of audit fees and future audit quality. We find that non-audit fees in the first year of engagement are negatively related to the propensity to LB. LB is significantly positively related to client importance for client firms switching from a non-Big N to another non-Big N auditor while the relation is insignificant for client firms switching from a Big N to another Big N auditor. The results of non-audit fees and client importance indicate that economic dependence does not motivate audit firms to lowball. Further, lowballing auditors tend to recoup their initial fee discounts in subsequent periods via increases in audit fees. Using multiple measures of audit quality, we do not find a significant relation between recovery of audit fees and future audit quality. Overall, contrary to regulators’ concerns, our results suggest that LB does not impair audit quality.     

Audit personnel salaries and audit quality

This study examines the relation between audit personnel salaries and office-level audit quality. We measure audit personnel salaries at the associate, senior, and manager ranks for Big 4 audit offices from 2004 to 2013, using unique individual-auditor-level data obtained from the U.S. Department of Labor. We find that offices that pay lower salaries have a higher percentage of clients that experience restatements. In related analyses, we also find lower levels of audit quality when audit employees are paid less, relative to other lines of service in accounting firms. Finally, we document positive and significant associations between salary and fees, suggesting that audit offices pass some of the cost of higher labor onto their clients. Overall, our findings provide important initial evidence on the role of audit salary and its relation to audit quality and audit fees.     

Audit office size,audit quality and audit pricing: evidence from small- and medium-sized enterprises

Using Swedish data, we investigate how audit quality and audit pricing vary with audit firm and office size. In contrast to prior studies, we use disciplinary sanctions issued against auditors not meeting the quality requirement as the measure of audit quality. We find no significant differences in the likelihood of sanctions between Big 4 audit firms and the fifth and sixth largest audit firms in Sweden (Grant Thornton and BDO). We refer to these collectively as ‘Top 6’. However, we find that the probabilities of warnings or exclusions from the profession are much higher for non-Top 6 auditors in Sweden than for Top 6 auditors. Furthermore, we find a strong negative association between the likelihood of sanctions and audit office size for non-Top 6 auditors. This association is insignificant for Top 6 audit firms. Audit fees follow a similar pattern and indicate that larger audit firms and offices put in more effort or have greater expertise. These results suggest that audit quality is differentiated in the private segment market. However, contrary to prior studies, our results suggest that the important dimensions are Top 6 versus non-Top 6 and the office size of non-Top 6 audit firms.     

Audit fee determinants and auditor premiums: evidence from the micro-firm sub-market

Despite the growing literature on the market for audit services, to date no study has examined the determinants of audit fees for the smallest auditees in the market. This study therefore provides some new theory and evidence on the determinants of the audit fees of micro-firms operating in the UK manufacturing sector. A key finding of the study is that in the highly competitive market under consideration, independent small auditees willingly paid a premium to be audited by a mid-tier or a (then) Big Six auditor, with the latter commanding the higher premium. It is concluded that these findings are consistent with Big Six (and, to a lesser extent, mid-tier) auditors commanding a brand premium stemming from the (perceived) higher quality audit conducted by large auditors, for which small firms are willing to pay a premium in order to benefit from associated ‘reputational’ and ‘signalling’ effects. The common finding that the explanatory power of audit fee models declines as a function of firm size is also examined. The empirical analysis confirms this effect, but evidence is offered that, rather than resulting from model misspecification, it is likely that audit prices of the smallest auditees are relatively insensitive to variations in corporate size, which may result from lower incremental economies of scale and minimum pricing.     

Does International Accounting Network Membership Affect Audit Fees and Audit Quality? Evidence From China

Regulators suggest that small audit firms join international accounting networks to reduce their resource constraints in serving large clients and providing high-quality service. Bills, Cunningham, and Myers (2016) investigate the issue in the United States and find that both audit fees and quality are higher for members of international accounting networks (i.e., member audit firms). We investigate the effects of network membership on audit fees and quality in China, a relatively weaker institutional environment than the United States. Using data of Chinese listed companies audited by non-Big N audit firms from 2001 to 2010, we find that member audit firms charge 3.9% higher fees than nonmember audit firms, much lower than the 30% fee premiums charged by U.S. member audit firms. We do not find consistent evidence that audit quality is higher for member audit firms. Overall, our results demonstrate that China's weak institutional environment may overwhelm the quality control brought by international accounting networks and that it may weaken or even offset the benefits of audit firms' participation in these networks, resulting in smaller or even no effects of membership on audit fees and quality.     

Does corporate social responsibility affect auditor-client contracting? Evidence from auditor selection and audit fees

We find that firms with higher CSR performance are more likely to choose Big N auditors and less likely to switch to non-Big N auditors, consistent with socially responsible firms demanding higher audit quality. Furthermore, we provide robust evidence that firms with higher CSR performance pay lower audit fees using both levels and changes models, suggesting that higher CSR performance reduces auditor engagement risk. Our analysis based on the difference-in-differences approach indicates that it is higher CSR performance that leads to lower audit fees, not vice versa. Overall, the results highlight the important role of CSR performance in auditor-client contracting.     

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.     

The effects of corporate governance and audit and non-audit fees on IPO Value

This paper examines the effects of non-executive board members, audit committee composition and financial expertise, and fees paid to audit firms on the value of 375 UK initial public offerings (IPOs). Empirical findings show that underpricing decreases in audit fees whereas it increases in non-audit fees. A higher proportion of non-executive directors on the firm’s board and audit committees with a higher proportion of non-executive directors and financial accounting expertise of their members positively moderate the inter-relationships between underpricing and both audit and non-audit fees paid by companies going through an IPO. Further investigations using the adjusted price-to-book value as a proxy for firm value at IPO confirm our main findings that internal governance mechanisms may complement services provided by the auditors in terms of generating higher valuations. Controlling for the simultaneous determination of audit and non-audit fees, our results remain consistent.     

Audit market concentration,audit fees,and audit quality: A cross-country analysis of complex audit clients

Regulators around the world are concerned about the potentially harmful effects of high audit market concentration on audit pricing and quality. However, results in the overall literature have failed to reach consensus on this issue. We contribute to this debate by arguing that the audit market is segmented and that concentration in the Big 4 segment of the market leads to higher audit pricing. Accordingly, our analyses use international data and focus on concentration within the Big 4 group of firms across countries. We find that audit fees are increasing in our concentration measure for clients where the barriers to entry by competing auditors are higher, as proxied by client size, international operations, and IFRS use. Finally, we find evidence that audit quality is decreasing in Big 4 market concentration for these types of engagements. This indicates a wealth transfer from shareholders to audit firms when auditor concentration is high because these complex clients are charged more, but receive audits that are of lower quality.     

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.     

Corporate employment,red flags,and audit effort

U.S. regulatory agencies and congressional oversight committees have expressed concerns that auditors often neglect red flags embedded in the operating characteristics of firms that misstate their financial reports. This study examines whether labor employment decisions, a major part of a firm’s operations, help predict accounting improprieties and consequently play a role in audit planning and pricing. We find that negative abnormal employment changes are associated with a higher likelihood of subsequent financial restatements, accounting irregularities, and lawsuits related to accounting fraud, and generally require greater effort from auditors as manifested by higher audit fees and longer audit report lags. Positive abnormal employment changes are associated with subsequent restatements and longer audit report lags, but not associated with fraud or audit fees. Taken together, the results are consistent with auditors recognizing the individual misstatement risks pertaining to companies’ employment decisions. These results suggest that standard setters, regulators, and practitioners should devote more attention to operational statistics to identify potential red flags.
