上市公司控制权转移与市场反应

国外有研究表明,控制权转移能给目标公司股东带来20%左右的超额收益率.本文通过考察我国1997-2003发生控制权转移的282个样本,发现控制权转移能给目标公司带来9%以上的累积超额收益率.而且,转移后变更行业、变更董事长或总经理、民营转给国有的样本转移时可获得的累积超额收益率甚至更高.最后,我们用多元回归模型进一步分析了累积超额收益率的影响因素,进一步证明行业变更、董事长或总经理变更、转移类型对控制权转移的市场反应有显著影响.

房地产宏观调控与地产公司股价波动的相关性——基于A股市场的实证分析

2005—2008年,频繁出台的房地产调控政策成为政策期间房地产上市公司股价波动和投资者财富效应的重要影响因素。本文研究发现,在事件窗内,一系列宏观调控政策对房地产上市公司产生了平均显著为负的累计异常回报率,对房地产上市公司产生总体负的股东财富效应;而在2008年9月之后,宽松的宏观政策对房地产上市公司股价的影响则相反。房地产公司股价波动受货币政策、土地政策、产业政策等不同政策的影响不同,对货币政策最敏感。横截面分析表明,资产规模越大、拥有国有背景房地产企业受政策冲击较小;沿海地区、以住宅开发销售为主的地产上市公司的股价对调控政策更敏感。     

Earnings Forecasts and the Information Contained in Spinoff Announcements

This study examines spinoff announcements in conjunction with financial analysts’ forecasts of earnings. The analysis shows that spinoff announcement abnormal returns are significantly related to the firm's information environment as proxieci by financial analysts’ earnings prediction errors. The findings also indicate that analysts significantly increase their short-term earnings forecasts in response to spinoffs, but do not significantly revise their long-term earnings forecasts. However, the earnings revisions are not significantly different across prediction error groups, which confirms that spinoff-related abnormal returns cannot be attributed solely to expected performance gains.

频繁并购重组与异常审计收费

以2012—2017年A股上市公司为样本,采用异常审计费用衡量审计师对上市公司频繁并购重组的风险溢价,探究企业频繁并购重组与审计师风险溢价收费的关系,研究发现企业频繁并购重组会导致审计师风险溢价提高。从商誉和盈余管理角度探究其路径机制发现,商誉和真实盈余管理是频繁并购重组导致更高审计师风险溢价两个重要中介变量,而应计盈余管理并没有发挥中介作用,即频繁并购重组企业操纵利润的手段倾向于采用真实盈余管理,而非应计盈余管理。     

The impact of European firms＇ economic conditions and financial performance on accounting quality

In this study the authors analyse the possible effect of firms＇ economic conditions and financial performance on accounting quality. Bradshaw, et al. （2004）, Gelos ＆ WEI （2005） stated that financial reporting quality is fundamental for investors and it affects international capital movements. Following Schipper ＆ Vicent （2003）, the authors estimated accounting quality by abnormal accruals and earnings persistence. The authors＇ contribution consists of investigating a huge number of firms from 17 European countries using unbalanced panel data. The authors found evidence that economic conditions affect accounting quality： big firms and those with high current earnings exhibit better financial information. These results are robust because they do not depend on the accounting quality proxy, even when the authors estimated regression with economical and financial factors alone or together. Financial performance does not seem to affect accounting quality. However, this relation is not linear because in high leveraged firms, the capital structure becomes determinant.     

公司诉讼风险对审计决策的影响研究——基于异常审计费用和审计意见的证据

近年来上市公司诉讼风险不断攀升,对审计师决策行为的影响日益凸显。基于这一背景,系统探讨公司诉讼风险对审计决策的影响,分别研究公司诉讼风险对审计费用决策和审计意见决策的影响,并考察在诉讼风险冲击下审计费用决策和审计意见决策间的关系,同时结合我国制度背景,研究法律环境差异性对两种决策之间关系的影响。研究发现：公司诉讼风险越高,审计师收取正向异常审计费用的概率越高,出具非标准审计意见的可能性越大;审计费用策略和审计意见策略之间存在替代关系,即审计师倾向于在出具标准审计意见时收取正向异常审计费用作为风险补偿。进一步研究表明,在外部法律环境薄弱地区,审计费用决策和审计意见决策之间的替代关系更加显著。研究结论有助于合理解释和评价审计师的决策行为,对监管机构规范审计师的行为有着一定的启示意义。
