Consistente com a literatura, o porte de auditoria tem sido utilizado como proxy de qualidade do serviço, e classificado como auditoria Big 6 e não-Big 6, sendo quanto maior o porte, maior a qualidade. A pesquisa abrangeu os estudos que utilizam acumulações discricionárias na estimação da manipulação da informação contábil. Por meio de uma revisão sistemática da literária, foram selecionadas 14 pesquisas empíricas, abrangendo Estados Unidos, Europa e Ásia. Com base na análise dos seus aspectos substantivos e metodológicos, a conclusão é que a magnitude da manipulação da informação contábil não é uniforme nos países estudados sugerindo que os ambientes cultural, institucional e legal podem influenciar a capacidade da auditoria em mitigar a ação discricionária dos gestores. / This study examines the relation between the audit firm size and the manipulation of accounting information. Consistent with the literature, firm size has been used as a proxy for quality of service, and classified as Big 6 and non-Big 6, and the larger the size, the better the quality. The survey covered the studies that use discretionary accruals in the estimation of earnings management Through a systematic review of literature, 14 empirical researches were selected, covering the United States, Europe and Asia. Based on the analysis of their substantive and methodological issues, the conclusion is that the magnitude of the accounting manipulation of information is not uniform in the countries surveyed suggesting that the cultural, institutional and legal environments may influence the ability of the audit to mitigate managers’ discretion.

本研究以台灣上市櫃公司及分析師投資報告為研究對象，探討會計師忙碌程度與審計品質之關聯性，以及產生學習或互斥效果。審計品質以裁決性應計項目、財務報表重編及迎合或擊敗分析師預期三種特性進行分析。 研究結果發現，會計師忙碌程度與裁決性應計項目、財務報表重編及迎合或擊敗分析師預期皆呈現顯著負相關。此結果表示，會計師忙碌程度愈高，受查公司管理當局進行盈餘管理之可能性愈低。本研究藉此結果推論，會計師忙碌程度愈高，透過累積查核經驗，促進知識改善，產生正向的學習效果，進而提高審計品質。 / This thesis examines the association between the busyness of auditors at partner level and audit quality and whether the association stems from learning effect or crowding-out effect, by using the listed firms’ data and the analysts’ reports in Taiwan. I use the following three measures of audit quality to examine my hypotheses: discretionary accruals, financial restatement, and meet or beat analyst forecast. The empirical results indicate that firms experience lower discretionary accruals, are less likely to restate financial statements and have lower likelihood of meeting or beating analysts’ expectations when auditors are busier. The results are consistent with the notion that auditor busyness is positively related to audit quality. Taken together, the findings provide strong evidence in favor for learning effect rather than crowding-out effect of auditor busyness. Further analyses reveal that the results remain unchanged, regardless of lead auditor busyness or concurring auditor busyness.
