講座摘要：
我們考察了資本市場投資者是如何看待共同意見審計報告的。利用盈馀反應系數(ERCS)作為投資者對審計質量感知的代言人yabo亚博app，我們觀察到了與無保留審計意見相比較，股價暴漲時的負盈馀驚喜。如果REAR涉及更大比例的未經集團合作伙伴審計的零部件公司yabo亚博app，那么ERCS就會更加不利yabo亚博appyabo亚博app。此外，我們還發現，在由四大審計機構審計的公司樣本中，負ERCs更為明顯。這些結果對不同子樣本的估計具有魯棒性，并使用收益-收益回歸模型的替代度量。
We examine how?capital market investors perceive the shared-opinion audit report (SOAR).?Using earnings response coefficients (ERCs) to proxy for investors’ perceptions of audit quality, we observe negative earnings surprise when the SOAR is announced as compared to unqualified audit opinions. The?ERCs?are more adverse if the SOAR involves a larger percentage of component firms that are not audited by the group engagement partner. Moreover, we find that the negative ERCs are more pronounced in the sample of firms audited by Big 4 auditors. These results are robust to estimation across various subsamples and using an alternative measure of earnings-returns?regression model.
