Abstract
Our study is motivated by the theory of credence goods in the auditing setting. We propose that audit committee accounting expertise should reduce information asymmetries between the auditor and the client, thereby limiting auditors’ ability to over-audit and under-audit. Consistent with this notion, our results indicate that when audit committees have accounting expertise, clients (1) pay lower fees when changes in standards decrease required audit effort; (2) pay a smaller fee premium in the presence of remediated material weaknesses; and (3) have a reduced likelihood of restatement when audit market competition is high. Our findings in the under-auditing setting generally are strongest among non-Big 4 engagements, consistent with non-Big 4 auditors being less sensitive to market-wide disciplining mechanisms such as reputation, legal liability, and professional regulation. We also provide evidence that the nature of audit committee members’ accounting expertise differentially impacts the committee’s ability to curtail over- and under-auditing.
