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.     

银行信贷顺周期性的微观行为特征与优化控制——基于青岛市大数据平台

银行信贷管理具有明显的周期性,尤其是在经济下行期银行的＂避险＂行为比较突出。基于青岛市大数据平台,本文对经济下行期银行信贷管理行为进行研究,力图总结出银行的微观行为特征。本文认为银行的风险敏感度和预见度并不高,行为多表现出短期应激性,主要表现是前置性强势和风险处置弱势的双重特征,并且银行在对待周期性行业和非周期性行业方面呈现出较大差异。银行的行为特征有其内在组织和市场根源因素,通过对根源因素开展可控性分析,对其优化控制可以缓解银行信贷的顺周期性。     

Are USDA reports still news to changing crop markets?

This study investigates whether major USDA reports still provide important news to changing crop markets. The news component of each report, or market “surprise,” is measured as a difference between the USDA estimate and its private expectation in corn, soybeans, and wheat markets. Changes in the relevance of USDA information are assessed by examining changes in the magnitude of market surprises and shifts in the futures price reaction to these surprises, which isolates the impact of each report. The stable size of market surprises over time suggests that competition from alternative data sources has not reduced the news component of USDA crop reports. Increasing price reaction to most reports, including those facing competition from alternative information sources, suggests that value of public information may be enhanced in uncertain markets affected by structural changes.     

Material weakness disclosures and restatement announcements: The joint and order effects

We examine differences in stock price, option volatility, and litigation reactions to restatement announcements that are associated with a material weakness (MW) disclosure. Contrasted with restatements that are not associated with any MW disclosure, our analyses reveal that firms that announce both a restatement and an associated MW experience significantly more negative market returns, greater implied volatility, and higher likelihood of class action lawsuits. Separating the restatements into timely reporters, where the MW precedes the restatement, and non‐timely reporters, where the MW is concurrent with or follows the restatement, we find that timely reporters experience more negative returns at the time of the restatement, relative to non‐timely reporters, suggesting that investors perceive the early MW disclosure to signal more pervasive control‐related problems. Interestingly, we find that timely and non‐timely reporters are equally likely to be sued, consistent with the argument that wrongdoing (through either a timely or non‐timely MW disclosure) provides stronger grounds for establishing scienter. However, timely reporters appear to secure more favorable litigation outcomes: they face higher likelihood of lawsuit dismissals and pay much lower settlements, compared to non‐timely reporters. Overall, our evidence provides new insights into how market participants incorporate information about internal control weaknesses into their perceptions regarding the economic implications of financial restatements, and financial reporting quality.     

Timing of earnings restatements: CEO equity compensation and market reaction

This study investigates the impact of chief executive officers’ (CEO) compensation on their choices regarding the timing of earnings restatements. The results indicate a negative relationship between options exercised and lags in disclosing the restated earnings, suggesting that managers who exercise options in a given year tend to release information quickly. This effect is more pronounced if the options are exercised after the dark period. We also find that the market penalises longer lags in the restatement disclosure. It seems that the CEO would try to optimise the timing of information release so as to balance the costs and benefits.     

关于构建我国药品不良反应保险救济机制问题的研究

2006年上海试点的“严重药品不良反应综合保险”初探市场,未能实现药企蜂拥而至的期望局面,而是十分落寂地收场。药品不良反应保险救济机制一直未能实现,已成为我国医药业一大难题。本文通过对药品不良反应定义的分析,探析了我国建立药品不良反应保险救济机制的可行性,再结合近期的“严重药品不良反应综合保险”的失败经验,提出了完善救济制度、累积相关数据、建立鉴定委员会、政府补贴并强制购买等相关的政策与建议。     

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。     

Scheduled macroeconomic news announcements and intraday market sentiment

We analyze the effects of scheduled macroeconomic news on intraday and daily market sentiment by comparing sentiment on news announcement dates with that on non-announcement dates. Announcements of macroeconomic indicators change neither intraday nor daily market sentiment. However, the directions of the announced values have asymmetric effects on intraday market sentiment, although they do not affect daily market sentiment. For example, an announcement of an increase in the gross domestic product (GDP) reduces short-term intraday market sentiment, whereas an announcement of a decrease in GDP does not significantly affect intraday market sentiment. We also find that the effect of intraday market sentiment on short-term market returns is greater following announcements of macroeconomic indicators that significantly affect intraday market sentiment.
