Empirical research regarding accruals quality

本研究通过检验可自由支配应计项目、现金流预测的准确性和应计项目质量，全面考察了上市公司上市前和上市后盈余质量的变化。本研究交叉检验了应计管理和实际管理在索克斯法案实施前后的变化以及盈余管理的决定因素之间的关系。我发现，在SOX法案通过后，只有机会主义应计项目管理衰落，而传达私人信息的应计项目管理通过与预测误差和应计项目质量的关联而保留下来。基于预测准确性与应计项目质量显著相关的结果，重大弱点披露公司的盈余管理很可能反映了管理层的机会主义。

This study investigates the changes in earnings quality in pre-and post-SOX periods comprehensively by testing discretionary accruals, accuracy of cash flow prediction, and accruals quality. This study cross-tests the association between the changes in accruals management and real management in pre-and post-SOX periods and determinants of earnings management. I find after the passage of SOX, only opportunistic accruals management declined and accruals management which conveys private information remains through the association with predictive errors and accruals quality. Based on the results that predictive accuracy is significantly associated with accruals quality, it is likely that earnings management of material weaknesses disclosing firms reflects managerial opportunism.
