This study investigates the impact on auditors' and clients' activities of Public Company Accounting Oversight Board (PCAOB) inspections of individual engagements. I find that both auditors and clients react to a Part I Finding, which identifies audit deficiencies on their inspected engagements. Audit firm effort increases on inspected engagements and non-inspected engagements of offices or partners that receive a Part I Finding, suggesting direct, as well as spillover, effects of the PCAOB inspections. The client is also more likely to switch auditors. However, auditor effort and financial reporting quality subsequently decline for inspected engagements that did not receive a Part I Finding. In these cases, clients are less likely to switch auditors. Additional analyses show that the auditor reaction depends on whether the auditor is an industry specialist, the client reaction depends on the size of the auditor, and effects on financial reporting quality depend on whether the deficiency is a firm-wide issue. Overall, these results suggest that both audit firms and clients care about the PCAOB individual engagement inspection process and, in several instances, gravitate toward the level set by the Part I Finding bar.

We examine the effect of large audit firms’ internal inspection programs, an important monitoring mechanism, on auditor effort and financial reporting quality. Internal inspections are often predictable, and engagement teams concentrate their effort on audits ultimately selected for inspections. The extra effort increases the likelihood of a favorable inspection rating. We find some evidence of improvement in financial reporting quality in the inspection year, suggesting that internal inspections are effective in deterring auditor shirking. Upon receiving a favorable rating, the engagement team reverts audit effort back to the preinspection level. However, if the rating is unfavorable, the team increases effort on future engagements of the client. This higher effort improves the client’s financial reporting quality if the internal inspection program is not deemed deficient by the PCAOB. Collectively, the results highlight the importance of an effective internal inspection program in improving financial reporting quality.

This paper examines whether the identity of the individual audit partners provides informational value to capital market participants beyond the value provided by the identity of the audit firms. Using data from Taiwan, where firms are mandated to disclose the names of the engagement partners, we find a positive association between the partner's quality and the client firm's earnings response coefficient. We also find a positive market reaction when a firm replaces a lower quality partner with a higher quality one. Moreover, we find evidence that firms audited by higher quality partners experience smaller initial public offering (IPO) underpricing and are able to obtain better debt contract terms. Overall, these results suggest that the quality of engagement partners matters to capital market participants.

As audits of public companies are labor intensive, require a variety of team members, and involve year-round work, practitioners and academics have increasingly focused on identifying audit production factors that drive audit quality. Using proprietary data, we analyze the cost-benefit tradeoffs of two audit production characteristics, client expertise and the relative amount of auditing done during the early phases of the audit, and find that both are associated with more effective audits and higher fees. We analyze whether the influence of these characteristics varies across audit team members. We find that middle manager production characteristics explain audit effectiveness and higher fees and relatively more so than those of lead/review partners. These results extend the literature and practitioner discussions about drivers of audit quality by highlighting the importance of middle management, which, to our knowledge, has largely been overlooked by the archival audit literature and regulatory guidance on audit quality indicators.

This paper examines the influence of labor market power in the audit profession. Using a dataset of online job postings, we confirm that audit offices in more concentrated labor markets have greater labor market power and exercise it in the form of higher skill requirements and greater required effort from their auditors, at similar or slightly lower wages. We then show that client firms of audit offices in more concentrated labor markets are less likely to restate their earnings and have lower absolute discretionary accruals. These findings are only present when employees have lower mobility across professions and geographies, consistent with audit offices’ power in the local labor market explaining the results. Collectively, our findings highlight the importance of labor market power in understanding audit quality. Data Availability: Data are available from the sources cited in the text.

This study focuses on the effect of disclosure processing frictions in labor markets. We go back in time 30 years ago and examine whether firms facing strong organized labor strategically responded to the implementation of the Electronic Data Gathering, Analysis, and Retrieval (EDGAR) system, which substantially reduced labor unions’ information processing costs. Consistent with firms having incentives to maintain an information advantage over unions for bargaining purposes, we find that they reduce financial statement disaggregation, the likelihood and frequency of management forecasts, and the proportion of good news forecasts. Our study is the first to investigate the implications of information processing costs for labor markets and suggests that an SEC mandate intended to reduce disclosure processing costs for investors caused unintended strategic responses by firms facing proprietary cost of disclosures in other markets.
