We evaluate and summarize the large body of audit fee research and use meta-analysis to test the combined effect of the most commonly used independent variables. The perspective provided by the meta-analysis allows us to reconsider the anomalies, mixed results, and gaps in audit fee research. We find that, although many independent variables have consistent results, several show no clear pattern to the results and others only show significant results in certain periods or particular countries. These variables include a loss by the client and leverage, which have become significant in comparatively recent studies; internal auditing and governance, both of which have mixed results; auditor specialization, regarding which there is still some uncertainty; and the audit opinion, which was a significant variable before 1990 but not in more recent studies.

This paper examines the accumulated weight of evidence in audit fee research. Research on factors related to audit fees has become more widespread in recent years, and there was a considerable upsurge in audit fee papers published subsequent to the data used in a recent meta‐analysis. In this paper, I use meta‐analysis to accumulate statistical results from more recent published studies as well as the earlier studies, and revisit the overall conclusions about the issues that are examined in audit fee research. The addition of audit fee studies from the more recent period shows that there is now evidence that audit fees are positively associated with internal control and with corporate governance. Evidence from previous studies regarding the audit fee premiums for Big 4 firms and industry specialist auditors, and about the positive relationship between non‐audit services and audit fees is reinforced, although in each case there are issues regarding the underlying research that need to be addressed in future studies. The analysis also shows that longer audit tenure is associated with higher fees. The paper concludes with suggestions for future research.

This paper examines evidence in New Zealand about whether auditors providing more non-audit services are less independent. Three sets of tests are used to address the issue. The first examines whether there is a relation between non-audit fees and audit fees, the second examines whether there is a relation between non-audit fees and audit report qualification or modification, and the third examines whether there is a relation between non-audit fees and stability of audit tenure. The results suggest a potential for the impairment of auditor independence in appearance when auditors provide non-audit services but no evidence of any impact on independence of mind.

In 2001, the US moved to regulate internal control reporting by management and auditors. While some jurisdictions have followed the lead of the US, many others have not. An important question, therefore, is the relevance of internal control to stakeholders. The more specific issue of the benefits of US-style regulation of internal control reporting is also topical. We review studies on the determinants of internal control quality and its economic consequences for stakeholders including investors, creditors, managers, auditors and financial analysts. We extend previous reviews by focusing on US studies published since 2013 as well as all non-US studies investigating IC quality including countries regulating IC disclosure as well as unregulated settings and both developed and developing economies. In doing so, we identify research questions where evidence remains mixed and new directions in which there are research opportunities. Three main insights arise from our analysis. First, evidence on the economic consequences of internal control quality suggests that the quality of internal control can have a significant effect on decision making by users of financial information. Second, the results of research on the empirical association between ownership structure, certain board characteristics and internal control quality is generally mixed. Empirical evidence concerning the association between audit committee characteristics and internal control quality generally supports a positive and significant association. Finally, while studies in non-US jurisdictions are increasing, opportunities remain to explore the determinants and consequences of internal control in other jurisdictions. Our review provides evidence for policy makers of whether there are benefits from requiring management and auditors to report on internal control over financial reporting.

This paper explores the value of financial statement auditing in the public sector. The study applies theory about auditing from the private sector as well as the public sector to explore ways in which public sector auditing can be expected to be valuable. It shows that there are a number of complementary explanations that can be applied to examine the value of public audit, including agency, signaling, insurance, management control, governance and confirmation explanations. The evidence from research and history is generally consistent with the agency and management control explanations. There is some support for the signaling and insurance explanations, while research evidence suggests that governance has differing impact in the public sector compared to the private. The confirmation hypothesis is also potentially relevant. Reviewing the history of the development of public sector auditing functions shows that at least some developments were consistent with explanations such as agency theory and management control. Auditing in the public sector is an area where more research is valuable. The paper concludes with a discussion of issues for further investigation.
