Research on extended external reporting assurance: An update on recent developments

Abstract

We review the recent literature on the assurance of Extended External Reporting published since the review published in 2021 in the Journal of International Financial Management & Accounting. Our review includes 50 articles published between 2020 and August 2023 across 30 journals ranked A*, A, or B on the Australian Business Deans Council 2022 Journal Quality List. We find that the literature continues to be dominated by positivist studies investigating the determinants and consequences of assurance. Studies on determinants examine carbon assurance, ownership, governance, and institutional themes. The consequences studies included in our review examine reporting-related outcomes and investors' decisions. Other (qualitative) studies we reviewed examine issues such as assurance providers seeking meaning in their work and their attempts to promote assurance beyond merely a verification tool. We highlight several avenues for future research that could inform the work of standard setters and regulators.

Audit evidence, technology, and judgement: A review of the literature in response to ED‐500

Abstract

In October 2022, the International Auditing and Assurance Standards Board (IAASB) issued Exposure Draft 500 (ED-500). This is focused on revising and integrating the standard auditors use when evaluating audit evidence during an external audit. This study contributes to the ongoing discourse as the IAASB evaluates feedback to ED-500 and executes its standard-setting agenda. We review academic literature published in the past 10 years to synthesize extant knowledge specifically on the use of technology and the application of professional skepticism during audit evidence evaluation. Our review offers factors the IAASB should consider when seeking to modernize and future-proof its standards, suggesting improvements to the proposed ED-500. We also identify fruitful avenues for future academic research.
