Audit partners’ gender and time variances of key audit matters

Purpose This study aims to examine whether audit partners’ gender affects the year-to-year changes (year-to-year additions and drops) of key audit matters (KAMs) identified in the audit report. This study also examines whether female audit partners’ audit experiences, accounting education and narcissism reduce the difference in time variances of KAMs reporting between female and male audit partners. This study defines the year-to-year additions and drops of KAMs as the time variance of KAMs. Design/methodology/approach Data of this study includes the audit reports of Australian Securities Exchange 300 companies for the period from 2017 to 2021. This study also applies the theory of female auditors’ preference for anchoring and availability heuristics. This study uses multivariate regression with robust standard errors clustered by the firms. This study also uses several robustness tests. Findings The findings suggest that female audit partners disclose fewer time variant KAMs in that they have a lower tendency both to add new KAMs and to drop old KAMs. Further analysis suggests that the differences between female and male audit partners decrease as the female audit partners’ experience increases or if the female audit partner possesses a bachelor’s degree in accounting. Female audit partners’ narcissism also reduces the gender gap in the time variances of KAMs. Practical implications The fact that female audit partners report more stable KAMs implies that there are differences between female and male audit partners in the way audit risk assessments are conducted, audits are planned and professional judgement is applied by female and male audit partners. Social implications The findings imply that female audit partners’ experience, accounting education and narcissistic personality can play a significant role in explaining the differences in audit outcomes produced by male and female audit partners. Originality/value This study is novel in showing that female audit partners report more stable and less time-variant KAMs. The findings of this study may inform audit firms and regulators that female audit partners’ experience, tertiary qualifications in accounting and narcissistic personality traits may be effective means of reducing the gender gap in auditing. The findings also imply that auditors’ observable and unobservable personality traits affect audit outcomes.
