This paper contributes to the literature on auditor industry expertise in many ways. First, it extends previous studies on this topic to examine whether industry specialists demonstrate different risk preferences in client acceptance decisions. The finding that partner-level industry specialists are more likely to accept less risky clients may partly explain why industry specialists have better quality clients.

This study draws attention to the potentially large issues involved with inconsistencies in the measurement of auditor industry specialization with a focus on audit fees and audit quality. The findings of this study suggest that audit fee-based measures should probably be prioritized by researchers and that previous empirical findings based on other measurement variables need to be re-examined. Results also show that choosing a market share approach or a portfolio approach has very significant consequences, so the decision should not be made absent-mindedly. Furthermore, the choice of absolute versus relative measures of ISP if not neutral, either, and the sensitivity tests indicated that ISP calculations are very sensitive to the industry classification used.

The results of this study are important to audit firm clients, audit firms, and audit regulators as they evaluate the benefits and costs of industry specialization. For auditors and their clients, the evidence indicates that specialist auditors in homogenous industries, even when complex accounting is involved, achieve economies of scale that are passed on to clients. Clients in homogenous industries appear to benefit from a lower cost audit without a decrease in audit quality. Moreover, audit firms may benefit from increased client retention in these industries because of their expertise and competitive price. And, though audit regulators have expressed concern about concentration in the audit market, the results indicate that concentration can improve audit firms’ economies of scale in homogenous and complex industries without reducing audit quality. As audit clients, audit firms, and audit regulators consider industry specialization, this paper provides support for auditor specialization in homogenous industries.

This study provides further support for the importance of office-specific characteristics on audit and financial reporting outcomes and provides evidence of the benefit of office-specific industry expertise. The study should be of interest to financial reporters and audit firms interested in reducing audit report lag times and to regulators and investors interested in increasing the timeliness of financial reporting information.

The authors contribute by providing some of the first evidence of service bundling in the economics of auditing literature. In doing so, they broaden the notion that strategic pricing occurs around audit switches. This study contributes to prior mixed findings of the existence of industry specialist premiums in the small-client segment, suggesting an additional reason why these mixed findings might occur. Where opportunities to package services are attractive, auditors may strategically price and discount audits with bundling premiums in mind. Where potential for such bundling opportunities is less attractive, it is possible the auditor may instead seek to generate premiums in the audit service.

The findings provide new evidence confirming the role of Big N auditors in corporate takeovers. In addition, the evidence suggests a positive association between deal completion and Big N target auditors. This information is critical to acquirer managers and investors, as ex ante acquirers can expect a lower deadweight loss associated with a failed M&A deal if the target firm employs a Big N auditor. Fund managers may find the discovery of the positive association between the target likelihood and engaging a Big N target auditor to be useful. Given recent evidence recommending a portfolio selection strategy based on the probability that a firm becoming a target in an M&A generates premium returns, auditor information might be utilized to screen a low cost M&A.

While theoretical literature has extensively examined the link between audit quality and firm value, very little empirical evidence has been provided as to the potential channels in which high-quality audits enhance firm value. This study extends and complements the existing line of research by providing useful insights into the role of audit quality in constraining managerial diversion or misuse of corporate cash resources. The results of this study are useful in assessing the effects of audit quality on firm value, specifically the market value of cash holdings.

The authors find support for the idea that auditors develop in-house rules to facilitate comparability within their clientele. These auditor style effects also appear to reduce comparability between clients audited by different auditors. Big 4 accounting firms may have an effect on another earnings attribute that has not previously been investigated, namely, accounting comparability. The authors find that firms audited by Big 4 auditors have greater accounting comparability than firms audited by non-Big 4 auditors, which suggests another dimension in which the two auditor groups differ. It is also the case that each Big 4 audit firm has its own “style,” which affects accounting comparability and is therefore another source of variation within the Big 4 group of auditors.

The fact that the Big 4 effect is generally insignificant indirectly supports the argument that the Big 4 distinction may reflect client and not auditor characteristics. The results suggest that differences in these proxies between Big 4 and non-Big 4 auditors largely reflect client characteristics and, more specifically, client size. The study has not resolved the question, although it encourages other researchers to explore alternative methodologies that separate client characteristics from audit-quality effects.

The results of this study are important for audit firms to consider when staffing their engagements, particularly for mid-tier accounting firms. The authors note that firms may want to consider allocating non-specialist staff among a few different industries. According to their research, there appears to be benefits due to the industry experience regardless of whether they have task-related experience. This allows for non-specialist auditors to continue gaining task-based experiences while expanding their industry-based experiences.
