Large audit firm premium and audit specialisation in the public sector

The outsourcing of public‐sector audits to the private sector is an important issue. This study examines the fee premium in the public sector by comparing audit fees between the government auditor and the Big5. The study (i) statistically adjusts for self‐selection bias, (ii) allows the slope coefficients in the audit fee model to vary between the Big5 and the government audit and (iii) estimates the counterfactual audit fee premium. The Big5 premium is around 23 percent. However, the variation in premium depends on whether the Big5 auditor is an industry or city specialist.     

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.     

Further evidence on mandatory partner rotation and audit pricing: a supply‐side perspective

This study examines effects of mandatory partner rotation (MPR) on audit fees of Australian‐listed companies. Using a fee changes approach, evidence of fee increases in year of the MPR driven by smaller offices of non‐Big 4 auditors is found, consistent with supply‐side resource constraint arguments. Broadly consistent findings are observed using a fee levels approach. Appointment of inexperienced partners to MPR engagements has no discernible effect on fees. Additional analysis of audit reporting lag indicates fee increases reflect additional audit effort as opposed to a pricing strategy. Overall, the evidence supports recent moves by policy‐makers to soften MPR requirements.     

What matters in audit pricing: industry specialization or overall market leadership?

Ferguson et al. (2003) report that audit industry fee premia primarily reside with joint national and city‐specific industry leadership as opposed to merely firm‐wide (national) industry expertise, suggesting auditor choice among the Big 5 is best conceptualized on joint industry specialization in city‐specific markets and nationally. The present study examines whether the prior results could be confounded by the presence of city‐specific overall market leadership effects. Our findings reaffirm that joint local and national auditor industry expertise is valued by audit clients. Furthermore, overall city‐specific leadership, by itself, also matters in fee determination and results in higher fees, although at a slightly weaker level of statistical significance.     

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.     

The effect of political visibility on audit effort and audit pricing

This study examines whether auditors adjust their effort and pricing decisions for political visibility. We argue, from the behavioural literature, that political visibility will create the need for more justification by auditors. Using data on actual audit fees, hours and billing rates for a sample of New Zealand public sector companies, we find that total audit fees are positively related to the number of press mentions (our proxy for political visibility). Consistent with our expectations we find that audit fees are monotonically related to audit fees. We also find that auditors increase the hours spent on the audit but not billing rates, which further suggests defensive bolstering by auditors.     

Female audit committee members and their influence on audit fees

We test the relationship between female representation on the audit committee and audit fees for 624 Australian companies in the year 2011. A positive relationship is found, leading to the conclusion that female presence on audit committees influences the quality of the external audit. Further, we find that gender is the significant audit committee characteristic in predicting audit quality and that women on the audit committee strengthen the positive relationship between firm size and audit fees, and between risk and audit fees. Conversely, we find that female representation dampens the positive relationship between complexity and audit fees.     

Audit fees and audit adjustments: evidence from Welsh local authorities

This paper exploits the availability of pre-audit financial statements to investigate the scale and incidence of audit adjustments and their impact on audit fees in Welsh local authorities. Adjustments to the politically-sensitive general fund, which represent a significant proportion of all adjustments, are associated with increased audit fees. The authors also found that audit adjustments on average result in more conservative reporting of the surplus/deficit and the balance on the general fund, with the number and value of downward adjustments exceeding those of upward movements.     

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.     

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 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.     

Agency costs and product market competition: The case of audit pricing in Greece

Jensen and Meckling (1976) argue that agency costs are not dependent on product market competition. However, elsewhere in the economics literature, theoretical analysis and empirical research have indicated that product market competition reduces agency costs by reducing the marginal cost of eliciting effort from agents. We investigate the relationship between product market competition and audit fee, as an example of agency cost. Taking advantage of a proprietary data set for Greek audit firms, we find that the audit fee and audit hours are inversely associated with client firm product market competition. We conclude that audit effort, as an agency cost, is reduced where competitive forces reduce the need for shareholders to bear the costs of monitoring agents.     

Effect of regulatory oversight on the association between internal governance characteristics and audit fees

We examine the relationship between internal governance, external audit monitoring and regulatory oversight for a sample comprising industrial companies and financial/utility companies subject to additional industry‐specific regulation. Our results indicate that the association between audit fees and board/audit committee independence and size are weaker for regulated companies. These observations are consistent with the notion that regulatory oversight partially substitutes the external audit as a monitoring mechanism. However, boards/audit committees with more multiple directorships demand a more extensive audit in the presence of regulatory oversight to protect their reputation capital. Our study enhances our understanding of the complex relationships among the major corporate governance elements.

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 the Multi-jurisdiction Disclosure System on audit fees of cross-listed Canadian firms

The Multi-jurisdiction Disclosure System (MJDS), a treaty between Canada and the United States (U.S.), was intended to facilitate the cross-listing of a firm's securities in the neighboring country. Under this system, eligible Canadian companies are allowed to use home-country documents to meet U.S. disclosure requirements and these documents are generally not reviewed by the Securities and Exchange Commission (SEC). We posit that the single-reporting requirement and lower SEC scrutiny may result in lower audit fees for MJDS firms. Based on audit-fee disclosures mandated by the SEC rule-making authority granted by the Sarbanes-Oxley Act of 2002, we find a negative association between audit fees paid by U.S. cross-listed Canadian companies and their use of the MJDS. This result suggests that the lower audit fees provide an economic incentive to use the MJDS. Thus, our study provides evidence that the implementation of the MJDS may help facilitate cross-border listings by reducing audit costs. Additionally, this study confirms, for Canadian firms, some of the audit-fee determinants reported in earlier studies.     

Effects of SOX 404(b) implementation on audit fees by SEC filer size category

This study provides novel information about the consequences of the Sarbanes-Oxley Act (SOX) by documenting differential audit fee shocks accompanying implementation of SOX 404(b) internal control tests and reports for clients in three size categories: large accelerated filers (LAFs), small accelerated filers (SAFs), and non-accelerated filers (NAFs). First, we find that although both LAFs and SAFs experience audit fee shocks attributable to 404(b), SAFs on average experience relatively greater fee shocks than LAFs (107.8% versus 84.6%; Table 6). Second, even though NAFs are not subject to 404(b) procedures, we document a 42.7% fee shock for NAFs. Our interpretation is that 404(b) generated an immediate increase in demand for audit services with no corresponding sudden increase in supply of experienced audit personnel, enabling audit firms to charge higher prices for all filers including NAFs. We find that audit fee shocks attributable to 404(b) are positively associated with audit offices’ bargaining power relative to clients, and that the effect of offices’ bargaining power is strongest for SAFs and weakest for NAFs. Although higher audit fees (with client characteristics held constant) are often considered an indicator of better audit quality, we find virtually no evidence that the massive fee increases in 2004 are accompanied by improvements in same-year or next-year audit quality, measured as decreases in discretionary accruals and a lower likelihood of subsequent restatements of audited financial reports.     

Governance regulatory changes,International Financial Reporting Standards adoption,and New Zealand audit and non‐audit fees: empirical evidence

This study examines the association between overseas and New Zealand governance regulatory reforms and New Zealand companies’ audit and non‐audit fees. Our models use temporal and International Financial Reporting Standards (IFRS) indicator variables to relate the timing of the fee changes to the incidence of the overseas and local reforms. We find that audit fees increased in New Zealand over 2002–2006. Such increases associate reliably with the transition to and adoption of NZ IFRS and not with earlier overseas governance reforms. Our study also documents a decrease in non‐audit fees over the same period, but we find no IFRS effect for non‐audit fees.     

The effects of audit firm rotation on perceived auditor independence and audit quality

Our study explores loan officers’ perceptions of auditors’ independence and audit quality under three experimental audit firm rotation scenarios. We use a case experiment with a between-subjects design to determine whether rotation of the audit firm impacts financial statement users’ perceptions of auditor’s independence and quality. Findings based on 212 useable responses indicate that loan officers do perceive an increase in independence when the company follows an audit firm rotation policy. However, the length of auditor tenure within rotation fails to significantly change loan officers’ perceptions of independence. Findings also indicate that neither the presence of a rotation policy nor the length of the auditor tenure within rotation significantly influences the loan officers’ perceptions of audit quality.     

Discussion of ‘Strategic pricing by Big 4 audit firms in private client segments’

This article discusses the paper by Dutillieux et al., (2013). The comments are in four main areas, regarding the importance of the research question, the setting in which the study is located, the theoretical development of the study and some thoughts regarding both supply‐ and demand‐side considerations around auditor change.
