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。     

中国货币政策对价格波动的影响

货币发行量对CPI变动具有负的影响。当前中国CPI居高不下,长期以来,中国一直存在着货币增速超过CPI增速、货币政策对资产泡沫的估算和调节能力有限、通胀指标难以确定等问题,针对这些情况,我们应综合运用货币政策工具,保持货币信贷合理投放,加大金融支持经济发展方式转变和经济结构调整的力度。完善人民币汇率形成机制,采取"外堵内疏"的策略,遏制国际投机资本冲击国内金融市场。     

Earnings quality,bankruptcy risk and future cash flows

Prior research suggests that the quality of accruals may be compromised where the magnitude of accruals is abnormally high, due to the presence of errors in the accruals‐estimation process (Dechow and Dichev, 2002; Richardson, 2003). A consequence of this is that abnormal accruals may not map into realised future cash flows to the extent that would normally be expected of accruals data. Indeed, the association may be insignificant if abnormal accruals consist primarily of estimation noise. Our study investigates whether abnormal accruals for UK firms provide incremental insight into future cash flows. In particular, our paper may be viewed as a development of Subramanyam (1996). We find a significant positive association between abnormal accruals and one‐year‐ahead operating cash flows. This provides a rationale for the pricing of abnormal accruals by the market (Subramanyam, 1996; Xie, 2001) and suggests that abnormal accruals are not merely the products of noise in the accruals‐estimation process. However, our results are conditional upon the probability of one‐year‐ahead bankruptcy risk (Charitou et al., 2004). We also find that abnormal accruals possess small but significant explanatory power for future cash flows even when controlling for the disaggregation of accruals into individual items (Barth et al., 2001).     

上市公司业绩预告与股票收益率的经验研究

运用上市公司财务与市场数据,对业绩剧变公司的业绩预告的特点、影响因素及业绩预告对股票价格影响的实证研究发现,业绩预告披露的可能性与业绩变动、基金持股比例、公司规模等因素有关,与风险、前十大股东持股比例等因素无关;业绩预告披露、年度财务报告披露期间的异常收益率与ROE变动比率、资产规模、信息披露细致程度等因素有关。在年报披露期间,业绩预告披露与否对异常收益率有显著影响,业绩预告会在一定程度上削弱年度财务报告信息对该公司股票的利空、利好效应.     

分析师能发现审计合谋吗？--基于我国上市公司的经验证据

以异常审计收费作为审计合谋的代理变量,研究分析师是否能发现审计合谋行为。研究发现,分析师跟踪人数会随异常审计费用的增加而显著减少,这说明分析师能觉察到审计合谋可能带来的风险,并通过放弃跟踪该公司的方式向市场传递信息;进一步研究发现,分析师对上市时间较长的公司,以及民营上市公司的异常审计费用更为敏感,跟踪数量下降较为明显。     

人民币汇率弹性的增大对利率稳定性的影响

汇率改革前后,汇率与利率之间的动态关系发生了系统性的改变。在均值意义上讲,人民币汇率弹性的增大降低了利率波动的幅度,利率对汇率的反馈机制有了一定的加强。实证检验证明,汇率改革后人民币汇率弹性的增大能稳定利率波动的假设只在长期内存在,而短期内人民币弹性的增大实际上加剧了利率的波动。     

内部审计质量与盈余管理——来自中国A股制造业上市公司的经验证据

通过对中国A股制造业上市公司2007年至2008年数据的分析,检验了高质量的内部审计质量与低水平的盈余管理间的关系。研究结果表明,内部审计质量与盈余管理抑制之间存在明显的相关性,从而为公司治理对财务报告的重要影响提供了新的经验证据。     

The Global Financial Crisis and Stock Market Reaction to Bank Loan Announcements

This study investigates how equity investors react to bank loan announcements in China using an event study methodology. By estimating the average Cumulative Abnormal Returns (CARs) over the event period and controlling for the impact of other factors such as borrower, lender and loan characteristics, we find that the overall reaction is negative. However, the results for the two sub-sample periods are different. After the onset of the Global Financial Crisis, the average CARs are no longer statistically different from zero, indicating higher lending standards and improvement in the quality of credit analysis of Chinese banks.     

社保基金持股信息的市场反应——基于中国资本市场数据

在阐释社保基金及其投资情况和相关理论的基础上,采用超额收益法和多元回归分析法,分析我国资本市场对2009年四个季度和2010前两个季度公布的社保基金持股信息的反应。研究结果显示,资本市场对社保基金持股信息具有强烈的市场反应,被社保基金持股的上市公司股价超额收益非常明显。造成这种现象的原因除了社保基金管理者对股市精准把握外,我国资本市场的效率不足、信息不对称及社会保险基金会计信息披露的缺陷也是重要原因。因此,我国应加强公司治理,提高资本市场效率,规范社保基金会计信息披露。     

Optimal vs satisfactory transparency: The impact of global macroeconomic fluctuations on corporate competitiveness

Being able to separate temporary global macroeconomic influences – caused by fluctuations in exchange rates, interest rates and inflation – from intrinsic performance – related to a superior product, production process or management – is crucial to assessing the development of a firm’s competiveness. Against that background, this paper analyzes institutions’ role in making firms supply outside shareholders with relevant information corresponding to satisfactory transparency from the shareholder perspective. Based on a sample of the 100 largest public European firms, it is found that no firm provided information to a level deemed satisfactory by the outside shareholder. One explanation may be that optimal transparency for the firm does not equal satisfactory transparency for the outside shareholder. However, the implementation of IFRS/IAS 1 in the EU as of 2005 and a company’s international cross-listing activities exhibit associations with a better supply of information and a narrowing of the gap. Shareholders in the Anglo-Saxon corporate governance system are provided with more relevant information than those in other corporate governance systems. The paper adds to the literature on the role of institutions in international corporate governance, with a particular focus on information asymmetries in an international business context.
