Conventional wisdom holds that joint audits would improve audit quality by enhancing audit evidence precision because \"Two heads are better than one.\" Our paper challenges this wisdom. We show that joint audits by one big firm and one small firm may impair audit quality, because, in that situation, joint audits induce a free-riding problem between audit firms and reduce audit evidence precision. We further derive a set of empirically testable predictions comparing audit evidence precision and audit fees under joint and single audits. This paper, the first theoretical study of joint audits, contributes to a better understanding of the economic consequences of joint audits on audit quality.

PurposeThis study assesses the perception of academics and practitioners of ramifications that may have impacted audit evidence quality during COVID-19 in Egypt.Design/methodology/approachA questionnaire was collected and designed regarding the factors affecting the quality of audit evidence during the COVID-19 pandemic using a five-point Likert scale, and detailed descriptive statistics and regression analyses were conducted.FindingsThe study finds that there is no significant association between social distancing (SD), changing in the economic environment (CEE), time constraint (TC) and stress on audit personnel (SAP) as repercussions of the COVID-19 pandemic with the quality of audit evidence (QAE). The disruption in operational results (DOR), changes in the internal control (CIC) and the stress on client personnel (SCP) significantly affect the quality of audit evidence. Moreover, there is a significant difference between Big and non-Big Four audit firms in terms of changes in economic conditions, internal controls, disruption of operational results and time-constraint variables. The latter has significantly affected the audit evidence quality for both academics and professionals.Practical implicationsDue to the implementation of SD and work-from-home policies, audit firms are highly recommended to invest more in digital programs and to be more adaptable to work-from-home, which policy and enhances the effectiveness and flexibility of communication between auditors and their clients.Originality/valueThis paper is one of the foremost papers that provides empirical evidence for the antecedents or variables that may affect audit quality evidence due to the COVID-19 pandemic.

This study provides both survey and experimental evidence to consider how social interactions between staff-level auditors and client management may affect staff auditors' perceptions and influence their decisions regarding the collection of audit evidence. During fieldwork, staff-level auditors have extensive interaction with client management. Survey evidence suggests that these staff-level auditors are often \"mismatched\" with client management, in terms of their experience, age, and accounting knowledge. Experimental results indicate that staff-level auditors may reduce the extent to which they collect evidence to avoid these interactions. Finally, the use of email communication with client management helped to mitigate the reduction in evidence collected caused by avoiding in-person interactions. Interestingly, when not collecting all the evidence, approximately half of the participants documented their findings in a vague or inappropriate manner, which would likely reduce the likelihood that reviewing auditors would identify a problem. Given the extent of audit evidence collected by young staff auditors, these findings have direct implications for workpaper and audit quality.

This study examines the impact of International Financial Reporting Standards (IFRS) adoption on audit fees. We first build an analytical audit fee model to analyze the impact on audit fees for the change in both audit complexity and financial reporting quality brought about by IFRS adoption. We then test the model's predictions using audit fee data from European Union countries that mandated IFRS adoption in 2005. We find that mandatory IFRS adoption has led to an increase in audit fees. We also find that the IFRS-related audit fee premium increases with the increase in audit complexity brought about by IFRS adoption, and decreases with the improvement in financial reporting quality arising from IFRS adoption. Finally, we find some evidence that the IFRS-related audit fee premium is lower in countries with stronger legal regimes. Our results are robust to a variety of sensitivity checks.

Purpose This paper aims to ask whether the implementation of the expanded auditor’s report, which included a requirement to disclose key audit matters (KAMs) in Thailand since 2016, has improved audit quality. Design/methodology/approach To answer this question, the authors examined audit quality two years before and two years after its adoption by analysing 1,519 firm-year observations obtained from 312 companies. The authors applied logistic regression analyses to the firm-year observations. Findings The authors found some weak evidence that KAMs disclosure improved audit quality because of auditors putting more effort into their audits and audits being performed thoroughly after the implementation of KAMs. Interestingly, the number of disclosed KAMs and the most common types of disclosed KAMs are not associated with audit quality. Only disclosed KAMs related to acquisitions are more informative because the presence of this type of disclosed KAMs signals the greater likelihood of financial restatements being made in a later year. Originality/value Unlike previous studies on the impact of KAMs disclosure on audit quality, which used discretionary accruals as proxy for audit quality, this study used the occurrence of financial restatements.

Purpose - The pressure is on organizations to go beyond automating their internal audit activities and develop and integrate internal auditing into business processes of the enterprise. This paper aims to propose a \"full power\" continuous auditing (CA) model with three key components: electronic audit evidence functions; intra-process auditing; and inter-process auditing.Design methodology approach - This paper follows a design science approach by identifying relevant problems from the current literature, defining the objectives of the study, designing and developing the \"full power\" CA model, and evaluating the model. The model supports business process-centric auditing and enhances the business monitoring capacities of organizations enabling the fulfillment of increasingly stringent compliance requirements with internal policies as well as external regulations.Findings - This work has attempted to fill the gap between the enterprise solutions offered by enterprise system providers and a structured approach to auditing within enterprise environments by proposing the IIPCA model which combines the automated controls inherent in the systems with continuous audits based on electronic audit evidence. The approach provides for auditing both within and between processes ensuring comprehensiveness of the audit process.Originality value - The paper makes a contribution by proposing a \"full power\" continuous auditing model on the principle of continuous monitoring and with predefined building block components; facilitating the integration of continuous auditing within business information processing in an enterprise using different building blocks; and giving practitioners insight on the adoption of the CA in the enterprise and how it will enhance their audit effectiveness, and audit efficiency.

This study employs the impact and mechanism of internal audit quality on the comparability of corporate accounting information. Using manually collected internal audit data, the study focuses on non-financial listed companies of A-share market spanning from 2007 to 2022 in China. The findings are as follows: (1) Internal audit significantly enhances the comparability of accounting information, the higher the quality of internal audit, the more pronounced its contribution. This conclusion remains robust after conducting endogeneity tests. (2) Mechanism testing reveals that internal audit enhances accounting information comparability through two channels: mitigating agency costs and improving financial information transparency. (3) Moderation effect test proves that the quality of internal control and the high-tech industry will strengthen the positive relationship between internal audit and comparability of accounting information, while the degree of industry competition and the level of capital occupation by major shareholders will weaken the positive relationship.

Purpose This paper aims to explore organisational intentions to use Big Data and Big Data Analytics (BDA) in external auditing. This study conceptualises different contingent motivating factors based on prior literature and the views of auditors, business clients and regulators regarding the external auditing practices and BDA. Design/methodology/approach Using the contingency theory approach, a literature review and 21 in-depth interviews with three different types of respondents, the authors explore factors motivating the use of BDA in external auditing. Findings The study presents a few key findings regarding the use of BD and BDA in external auditing. By disclosing a comprehensive view of current practices, the authors identify two groups of motivating factors (company-related and institutional) and the circumstances in which to use BDA, which will lead to the desired outcomes of audit companies. In addition, the authors emphasise the relationship of audit companies, business clients and regulators. The research indicates a trend whereby external auditors are likely to focus on the procedures not only to satisfy regulatory requirements but also to provide more value for business clients; hence, BDA may be one of the solutions. Research limitations/implications The conclusions of this study are based on interview data collected from 21 participants. There is a limited number of large companies in Lithuania that are open to co-operation. Future studies may investigate the issues addressed in this study further by using different research sites and a broader range of data. Practical implications Current practices and outcomes of using BD and BDA by different types of respondents differ significantly. The authors wish to emphasise the need for audit companies to implement a BD-driven approach and to customise their audit strategy to gain long-term efficiency. Furthermore, the most challenging factors for using BDA emerged, namely, long-term audit agreements and the business clients’ sizes, structures and information systems. Originality/value The original contribution of this study lies in the empirical investigation of the comprehensive state-of-the-art of BDA usage and motivating factors in external auditing. Moreover, the study examines the phenomenon of BD as one of the most recent and praised developments in the external auditing context. Finally, a contingency-based theoretical framework has been proposed. In addition, the research also makes a methodological contribution by using the approach of constructivist grounded theory for the analysis of qualitative data.

Purpose This study aims to examine declines in audit quality after the COVID-19 travel restrictions/stay-at-home orders were issued in the USA in early 2020. Design/methodology/approach Taking advantage of variation in the dates of stay-at-home orders issued by different US states, this study identifies engagements that were significantly affected by the lock down orders. Findings The results suggest that engagements affected by the restrictions produced lower audit quality, as measured through restatements and discretionary accruals, relative to those completed before COVID-19 travel restrictions/stay-at-home orders. Further analysis reveals that this decrease in audit quality was attributable to firms with high inventory relative to assets, high R&D expenses relative to assets and non-Big 4 auditors. Practical implications This study finds that the restrictions on physical and on-site interaction caused auditors to universally struggle with resource/judgment-intensive accounts such as inventory and R&D expenditures. The results suggest that while Big 4 auditors managed to maintain their status quo level of audit quality following COVID-19 restrictions, non-Big 4 auditors were unable to overcome the challenges of an online work environment and their audit quality declined. Originality/value To the best of the authors’ knowledge, this paper is the first to empirically examine changes in audit quality as a response to a substantial change in auditors’ working environment due to the global health crisis. As work-from-home becomes more prevalent in audit firms, the results suggest that, on average, this move does diminish audit quality.

Exploiting a natural experiment in which voluntary audits replace mandatory audits for U.K. private companies, we analyze whether imposing audits suppresses valuable information about the types of companies that would voluntarily choose to be audited. We control for the assurance benefits of auditing to isolate the role signaling plays by focusing on companies that are audited under both regimes. These companies experience no change in audit assurance, although they can now reveal for the first time their desire to be audited. We find that these companies attract upgrades to their credit ratings because they send a positive signal by submitting to an audit when this is no longer legally required. In contrast, companies that dispense with being audited suffer downgrades to their ratings because avoiding an audit sends a negative signal and removes its assurance value.
