Zum Einfluss der Mandatsdauer des Abschlusspr��fers auf die Pr��fungsqualit?t

This study provides evidence on the relation between auditor tenure and audit quality. It is motivated by calls for mandatory auditor rotation, which are based on concerns that longer auditor tenure reduces auditor independence and thus audit quality. Earnings management is used as proxy for audit quality and is measured by absolute and signed performance-adjusted-Jones-model discretionary accruals. Multivariate analyses, controlling for additional firm and auditor characteristics indicate lower earnings management with longer auditor tenure. This result suggests that, in the current environment, mandatory limitations on the length of auditor-client-relationship would result in lower audit quality.
