The effect of engagement partner workload on audit quality

Purpose: Auditing studies have shifted the research focus from the audit firm level to the individual audit partner level in recent years. Motivated by the call from Lennox and Wu (2018) to explore the effect of audit partners’ characteristics on audit quality in the US, this study aims to develop a new measure of engagement partner workload (EPW), which includes both the size and number of clients audited to test the effect of EPW on audit quality. This study also examines the moderating effect of the partner firm size on audit quality. Design/methodology/approach: To test the effect of the EPW on audit quality, this study runs multivariate regressions of EPW on each specific client’s discretionary accruals and audit report delays. This study also runs a logistic regression of EPW on clients’ probability of having small profit increases to meet performance benchmarks. Findings: Results of the hypotheses show that partner workload is positively related to audit quality. The results indicate that partners with larger, but fewer, clients conduct higher quality audits. Further analysis indicates that the relationship between partner workload and audit quality only holds for partners from the non-Big 4 firms. Originality/value: This study contributes to the literatures of both audit quality and audit partner characteristics, and the results complement initial research aimed at identifying US partner-related characteristics that influence audit quality.
