This study aims to examine the effect of audit firm tenure (AFT) on corporate tax avoidance (CTA) and the moderating effect of the COVID-19 pandemic.

The sample comprises 41,074 firm-year observations from 32 countries from 2015 to 2020, for which data are collected from various sources: financial data from the Refinitiv database, country corporate tax rates from the Tax Foundation, and other country-level data from the World Bank database. The authors use the book tax difference to measure CTA and multiple proxies for AFT.

This study finds that a longer AFT is associated with higher CTA, confirming the notion that long AFT impairs auditor independence. The findings remain robust when considering various AFT proxies, incorporating Hofstede’s cultural factors, using weighted least-squares estimation and addressing endogeneity through propensity score matching. This study also finds a non-linear relationship between extended client and auditor relationships and CTA, supporting the mandatory audit firm rotation regulation and increasing investors’ caution regarding the consequences of extended client–auditor relationships on firm behaviour.

This study offers new evidence on the effect of the COVID-19 pandemic on the link between AFT and CTA and documents a non-linear relationship between AFT, which has not been addressed in prior studies.

The findings of this study have several significant practical implications. First, governments and policymakers gain insights into the consequences of extended auditor–client relationships, hence calling for a review of auditing and taxation regulations. Second, the findings provide important insights into the issue of auditor independence, especially during long engagements and crises such as COVID-19. Finally, investors and tax authorities should be more cautious about the risks of aggressive tax avoidance during crisis periods.

To the best of the authors’ knowledge, this is the first study to use a global data set to investigate the effect of AFT on CTA during the COVID-19 pandemic.

This study aims to investigate the impact of audit fees on audit quality, the impact of audit quality on firm value and whether these effects are conditional on audit tenure by bringing evidence from an emerging market.

Different regression techniques are used, such as logistic regression, probit regression, ordinary least squares regression and fixed effects regression. The authors used panel data of 80 nonfinancial Egyptian-listed firms over 2016–2020.

The authors found a significant positive relationship between audit fees and audit quality and a significant positive relationship between audit quality and firm value. Furthermore, the authors found that the positive relationship between audit fees and audit quality is less pronounced for higher audit tenure firms. Finally, the authors also found that the positive relationship between audit quality and firm value is stronger for lower audit tenure firms.

To the best of the authors’ knowledge, this is the first study to bring evidence from an emerging African market about the joint association between audit tenure, audit fees, audit quality and firm value. It provides beneficial insights to regulators regarding the possibility and the benefits of improving audit quality, which is critically needed in contexts with weak governance systems.

This paper aims to examine whether the audit committee moderates the relationship between audit quality and market reactions.

Using fixed effects and the GMM model for robustness, the study used 472 publicly listed firms on South Africa’s Johannesburg stock exchange spanning a period of six years from 2014 to 2019.

Results obtained show that audit quality impacts market reactions through share price and adjusted market returns. And, that the audit committee moderates the relationship between audit quality and market reactions in South Africa’s publicly listed firms. An effective audit committee is expected to play a crucial role in overseeing the audit process, ensuring the independence of auditors and promoting transparency and accountability which in turn impacts asset prices.

The study implies that governments and regulatory bodies in other developing economies could strengthen regulations about companies’ Acts, how firms regulate themselves and more so audit committees. Firms can also strive to make sure that audit committees are staffed with experts to promote higher audit quality and investor attention to get access to the much-alluded capital.

To the best of the authors’ knowledge, the study adds value by being the first to explore the subject matter of the importance of audit committees in defining audit quality and market reactions in publicly listed firms. The research adds to the body of knowledge on corporate governance and audit quality. It provides a case study specific to the South African context, contributing to the global literature on these topics.

The primary objective of this paper is to investigate the relation between the joint provision of sustainability assurance and the readability of sustainability assurance statements. Additionally, it explores whether the presence of a female assurance partner influences the relation between the joint provision of sustainability assurance and the readability of sustainability assurance statements.

We analyzed a dataset comprising 882 firm-year observations from companies operating in sustainability sensitive industries for the period that spans the years 2016–2018.

The research indicates that joint sustainability assurance provision is associated with a more readable sustainability assurance statement, consistent with the “four-eyes” principle. Furthermore, the presence of a female assurance provider influences the joint assurance provision’s impact on sustainability assurance statement readability. Collectively, these results remain robust as they hold unchanged after controlling for endogeneity concerns.

This study provides novel insights into the recent sustainability assurance literature, being the first to examine joint assurance provision, assurance partner gender and sustainability assurance statement readability.

This study has the potential to catalyze regulatory and policy initiatives by providing compelling evidence in favor of mandating joint audits within the area of sustainability assurance practices. Additionally, this research contributes to the ongoing discussion about gender diversity in accounting and nonaccounting assurance firms, providing evidence of the positive impact of female assurance partners on sustainability assurance statement readability.

The regression results provide preliminary evidence on how the presence of a female audit partner influences the relationship between the sustainability assurance joint provision and sustainability assurance statement readability, an issue that has not been examined before.

This study aims to examine how new regulation changes for the auditor’s report, so-called key audit matters (KAMs), influence tax avoidance.

This study uses data from firms listed on the Omani capital market over the period 2012–2019 and analyzes these data using pooled panel data regression with a robust standard error. It uses two common proxies for tax avoidance and two measures for the KAMs disclosure requirement.

This study finds a sharp decrease in the effective tax rate following the introduction of KAMs disclosure and the issuance of more KAMs in audit reports. This result is supported by several robustness checks. In an additional analysis, the authors observe interesting results, indicating that real earnings management mediates this association, while the audit committee plays a moderating role. The authors do not find a moderating effect of Big4 on this association, but find discrepancies within the Big4 firms in relation to this moderating effect.

The results of this study indicate that although the introduction of the KAMs disclosure requirement may have positive consequences, it may also lead to unintended negative consequences. This conclusion has not been comprehensively reported in literature.

This study aims to examine the mediating effects of corporate governance mechanisms like the board of directors on the association between disruptive technology adoption by audit clients and the risk of material misstatements, including inherent risk and control risk. In particular, the authors study the mediating effects of board characteristics such as board size, independence and gender diversity.

Based on a sample of 100 audit clients listed on the FTSE 100 from 2015 to 2021, this study uses structural equation modelling to test the research objectives.

The findings indicate a significant and negative association between disruptive technology adoption by audit clients and inherent risk. However, there is no significant evidence observed for control risk. The utilisation of disruptive technology by the audit client has a significant impact on the board characteristics, resulting in an increase in board size, greater independence and gender diversity. The authors also find strong evidence that board independence mediates the association between disruptive technology usage and both inherent risk and control risk. In addition, board size and gender exhibit distinct and differential mediating effects on the association and across the two types of risks.

The study reveals that the significant role of using disruptive technology by audit clients in reducing the risk of material misstatements is closely associated with the board of directors, which makes audit clients place greater emphasis on the construction of effective corporate governance.

This study offers essential primary evidence that can assist policymakers and standard setters in formulating guidance and recommendations for board size, independence and gender quotas, ensuring the enhancement of effective governance and supporting the future of audit within the next generation of digital services.

With respect to relevant stakeholders, it is imperative for audit clients to recognise that corporate governance represents a fundamental means of addressing the ramifications of applying disruptive technology, particularly as they pertain to inherent and control risks within the audit client.

This study contributes to the existing literature by investigating the joint impact of corporate governance and the utilisation of disruptive technology by audit clients on inherent risk and control risk, which has not been investigated by previous research.

Following recent high-profile audit failures, concern has been expressed that auditors are not demonstrating sufficient skepticism when exercising professional judgment. In particular, client assumptions and estimations relating to hypothetical valuations in financial reporting are not being challenged. This paper seeks to address the issue by advancing a decision-making framework aimed at guiding auditors beyond regulatory reductionist thinking towards an enhanced understanding of the cognitive processes which shape professional judgment in forming a reliable audit opinion.

Drawing on the normative philosophical and theological teachings of Bernard Lonergan, the authors' decision-making framework embodies reflective thinking and the data of consciousness to highlight the central role played by enquiry in the dynamics of understanding, judgment and decision-making. Such enquiry elicits challenge of the management bias inherent in hypothetical valuations.

Auditing through a Lonerganian lens allows auditors to reflect on their approach to objective decision-making by offering a set of cognitive tools to enhance the enquiry essential for nurturing professional skepticism.

This paper contributes to the literature by developing the somewhat neglected discourse on the cognitive processes essential for professional skepticism and audit judgment. The authors demonstrate how Lonerganian self-appropriation intensifies an awareness of the recursive cognitive activities pertinent to objective judgment and decision-making. This awakened consciousness has the potential not only to change how auditors question evidence to make informed judgments and decisions, but also to normalize the practice of challenge.

This study aims to examine the association between non-audit fees and audit quality by using the context of gender-diverse audit committees. Further, the authors assess whether this link is moderated by industry-specialist auditors.

This study used non-financial FTSE-350 firms over the period of seven years. In addition, the authors use ordinary least squares regression to test the research hypotheses.

The authors find that female directors on audit committees are negatively related to non-audit fees, suggesting that non-audit fees reduce audit quality. Moreover, the results indicate that industry-specialist auditors positively moderate the link between gender-diverse audit committees and non-audit fees. This suggests that non-audit fees improve audit quality when the auditor is an industry-specialist.

The study does not support blanket restrictions on non-audit fees. It recommends regulators to consider industry expertise of auditors when devising non-audit fee restrictions. Moreover, the findings of this study have implications for firms aiming to understand whether non-audit fees could be used for enhancing audit quality.

By using the context of female directors on audit committees, the authors conclusively assess the link between non-audit fees and audit quality. Further, this study provides a more robust evidence on whether industry-specialist auditors affect the relationship between non-audit fees and audit quality.

The complexity of property valuation, coupled with valuers’ cognitive limitations, makes some degree of error inevitable in valuations. However, given the crucial role that valuations play in the efficient functioning of the economy, there is a need for continuous improvement in the reliability of reported values by enhancing the quality of the decision-making process. The purpose of this paper is to review previous research on valuation decision-making, with particular interest in examining the approaches to improving the quality of valuation decisions and identifying potential areas for further research.

The paper adopts a narrative approach to review 42 research articles that were obtained from Scopus and Web of Science databases and through author citation searches.

Our findings show that existing literature is skewed towards examining the use of technology in the form of decision support systems (DSS), with limited research attention on non-technological (i.e. behavioural) approaches to improving the quality of valuation decisions. We summarise the non-technological approaches and note that much of the discussions on these approaches often appear as recommendations arising from other studies rather than original investigations in their own rights.

We conclude that studies investigating the effectiveness of the non-technological approaches to improving valuation decision-making are lacking, providing various avenues for further research.

This paper presents the first attempt to provide a comprehensive overview of non-technological approaches to improving the quality of valuation decisions.

The study of the relationship between external auditing services and investment deviation in a French setting has received relatively little research attention thus far. There are insufficient indicators to measure audit quality and then have a measurable link to investment efficiency. This study is motivated by such a research gap as well as the important role of auditing services in assuring investment efficiency. The purpose of this study is to test whether a good audit quality service improves corporate investment awareness in French-listed companies and contributes to establishing a comprehensive analysis framework for inefficient investment and how audit services have become an important tool to reduce the investment deviation of listed companies in France.

Based on a sample of 89 non-financial French firms listed on the Stoxx 600 Index from 2015 to 2021, this study uses feasible generalised least squares (FGLS) regressions to study the relationship between investment deviation and auditing service quality.

After running an FGLS regression model for two firm groups (overinvestment and overinvestment groups) and testing for a set of control variables, especially COVID-19, the findings show a non-linear correlation between audit service and corporate investment deviation. Both underinvestment and overinvestment decisions are negatively and statistically significantly impacted by audit indicators. Furthermore, involving a high-quality specialised auditor may enhance overall monitoring and lead to a lower investment deviation level. Overall, the empirical results show that a high-quality audit service enhances the investment efficiency of French-indexed companies.

This study offers crucial information that audit regulators can use to better appreciate the advantages of high audit quality and to take seriously the policy issues that affect it. Board members are urged to provide excellent audit quality that improves investment efficiency with careful consideration.

This study contributes to the existing audit literature by illuminating the effect of audit quality services on investment deviation to show a deeper understanding of the factors that contribute to the differences in prior studies’ findings in the field of audit quality impacts.
