Audit quality and earnings management: evidence from rural and community banks in an emerging economy

Purpose - This paper provides insights into the impact of audit quality on restraining earnings management of rural and community banks (RCBs) in an emerging economy. Design/methodology/approach - A two-step generalised method of moments, absolute discretionary accruals using the modified Jones model, and multivariate regression are used to test 215 firm-year observations of 43 RCBs in Ghana. Findings - The findings suggest a positive association between audit quality, proxied by audit firm ranking, in restraining earnings management. Specifically, the association is significant for B1-ranked audit firms and higher than B-ranked audit firms, whose observed discretionary accruals to total assets ratio is 36.6% higher than B1. Also, a negative statistically significant relationship is found between auditor specialization and earnings management, as RCBs that engage specialized auditors are found to have a lower ratio of discretionary accruals to total assets than RCBs that engage unspecialized auditors. Research limitations/implications - RCB’s annual reports data for the research was from 2014 to 2018. The 2019 and beyond annual reports data could not be added because the study was conducted during 2019 first quarter, by which time the year had not ended, and that constrained the sample size. Practical implications - Evidence from this study has policy implications for regulators and audit monitors in their efforts to improve AQ and minimise financial misreporting through the ranking of audit firms. As RCBs are encouraged by the findings to engage the services of higher-ranked audit firms, lower ranks will eventually be encouraged to improve quality performance in a bid to improve their ranking, which will consequently help in the minimisation of financial manipulations in RCBs financial reporting. The contemporary approach of ranking audit firms into A1, A, B1, B, C and D increases competition in the audit market space in improving quality audits more than the traditional approach of dividing audit firms into only big-4 and non-big-4. There is also a need for regulators to encourage RCBs to engage auditors who have specialized in the RCB sector so that their experience can be leveraged in minimizing EM. Originality/value - To the best of the authors’ knowledge, there is no academic study that explores the impact of audit quality proxied by audit firm ranking and auditor specialisation, on earnings management using hand-collected data sets from non-listed rural banks in an emerging economy. The paper, therefore, fills a research gap in rural financial institution auditing literature.
