Audit Firm Rotation, Auditor Specialization, and Audit Quality in the Municipal Audit Context

Abstract

ABSTRACTThe topic of audit firm rotation has been debated internationally for several decades. To inform the debate, we study the effects of audit firm rotation policies on audit quality in a government audit market. Using audit firm rotation data and audit quality measures from the Florida government audit market, a setting where procurement policies vary, we find that rotation policies are indirectly associated with higher audit quality. In particular, mediation analysis suggests that the consequences of policies that encourage Florida municipalities to consider rotation impact audit quality by encouraging the use of auditors that specialize in governmental audits, rather than auditor independence, which is frequently argued to support mandatory rotation.
