The effect of audit engagement partner professional experience on audit quality and audit fees: early evidence from Form AP disclosure

Purpose - The purpose of this study is to examine the effect of audit engagement partner's professional experience on audit quality. The authors also investigate the relationship between the audit partner's experience and audit fees in both Big 4 and non-Big 4 accounting firms. Design/methodology/approach - Since the Public Company Accounting Oversight Board (PCAOB) officially enacted Rule 3211 in 2017, US accounting firms are required to disclose detailed information of engagement partners in Form AP (PCAOB, 2015b). The authors obtained a sample of 2,283 audit partners from Form AP and hand collected their individual professional experience data through Certified Public Accountant (CPA) database, corporate disclosure and social media sites (e.g. Linkedin). Econometric models with fixed effects are used in this study to test our hypotheses. Two-stage least square (2SLS) model is used in the robustness test. Findings - The authors find that the relationship between audit engagement partner's professional experience and audit quality is concave. It indicates that audit quality is increasing during the early stage of engagement partners' career and then decreases as the partners approaching the late-career phase. Further, the authors find that partner's professional experience is positively associated with audit fees in non-Big 4 accounting firms but not significantly associated with audit fees in Big 4 accounting firms. Practical implications - The finding of how auditor experience impacts audit quality can be useful for accounting firms to better plan their staffing in auditing engagements. This study’s results are also helpful for small accounting firms to optimize their pricing strategy. Originality/value - This study provides new empirical evidence about the relation between auditor professional experience and audit quality. Furthermore, the authors extend the literature of audit fee determinants by testing the joint effects of audit firm-level factors and auditor individual-level professional experience on audit fees.
