Auditor Tenure and Quality of Financial Reporting
研究发现审计师任期通常提升报告质量，但当客户诉讼风险高时，任期越长反而导致盈余向下偏差越大，损害报告质量。
Prior studies in general suggest a positive association between auditor tenure (the length of an auditor–firm relationship) and reporting quality (the informational content of reported earnings). In this study, we present evidence that the association is reversed when clients represent increased litigation risks to their auditors. Featuring downward biases in reported earnings as a measure of reporting quality that stem from auditors’ minimization of costs from potential audit errors, we argue that the magnitude of such downward bias decreases in auditors’ experiences with their clients (tenure improves reporting quality). Furthermore, we predict that longer auditor tenure is associated with larger downward bias for firms with increased audit risks (tenure impairs reporting quality). Using non-operating accruals as proxy for downward bias in reported earnings, we find robust empirical evidence in support of our prediction.
