股权分置改革均衡对价

本文根据政策中性原则与套利分析理论推导出市场均衡条件下的股权分置改革对价公式，对46家试点公司和进入全面股改后推出的前两批72家公司对价方案进行剖析，认为部分上市公司对价支付比例存在明显不合理．并利用博弈论的观点分析了试点公司不合理对价方案获得高票通过的原因。最后，对上市公司股权分置改革的时机与成本关系进行了定量分析，认为在一个相对较短时间内解决股权分置问题．对于非流通股东而言最为经济。     

Asymmetric information and joint venture performance: theory and evidence for domestic and international joint ventures

The increased number of perspectives on joint ventures (JVs) raises important issues for theory development on interfirm collaboration. In this paper, we bring together two key theoretical perspectives on joint ventures—the asymmetric information perspective and the indigestibility view. On a theoretical level, we focus on the relationship between these two different explanations of joint ventures. We also present new evidence on the firm valuation effects of JVs in domestic and international investment contexts. The findings lend support to the asymmetric information perspective on resource combination through joint ventures. Copyright © 2000 John Wiley & Sons, Ltd.     

The reaction of firm ex ante cost of equity capital to the resolution of shareholder class action lawsuits

Existing research provides evidence that providers of capital (banks, public debt, and equity) all increase the expected return on securities after the initiation of a shareholder lawsuit. Many of these lawsuits are dismissed or settled with trivial monetary penalties, which suggests that an across-the-board permanent increase in the cost of capital is misguided. After estimating the probable outcome of a shareholder lawsuit using only information available at the time the shareholder lawsuit is filed, we study the resolution of shareholder lawsuits to determine if market participants adjust their expected return after a case is resolved. We find an increase (decrease) in the ex ante cost of equity capital when there is a surprise settlement (dismissal), which is consistent with an efficient market. Further, we present evidence consistent with equity market participants monitoring the progress of shareholder lawsuits prior to resolution. Overall, our results suggest that firm ex ante cost of equity capital only changes after the resolution of a shareholder lawsuit if the outcome of the case is different than initially predicted.     

全流通时代大股东股份减持的问题与对策

股权分置改革完成后,大股东所持有的限售股取得了上市流通权。为了满足自身利益最大化的要求,大股东频频在二级市场上进行股份减持。根据我国资本市场的实际,在大股东股权减持的过程中暴露出一些主要问题,所以需要采取一些针对性的对策措施,包括丰富大股东出售股票的渠道,严格信息披露,弱化大股东的信息垄断优势,建立健全大股东股份减持的制度规定等措施。     

Large Shareholder Tunneling and Risk of Stock Price Crash： Evidence from China

Although several studies have examined the economic consequences of large shareholders＇ tunneling behavior, little attention has been paid to the negative effects of tunneling on firms＇ extreme events. In this article, we investigate how tunneling behavior affects firm-level stock price crashes. The findings indicate that the probability of stock price crashes is positively associated with the extent of tunneling behavior by large shareholders. The positive relationship is more pronounced after the split of share structure reform and is moderated by the firm＇s financial conditions. This study contributes to the emerging body of literature focusing on the economic consequences of tunneling and stock price crashes. The conclusions drawn from the study also provide a frame of reference for investor protection and investment portfolios based on large shareholders＇ tunneling behavior in China.     

自媒体帮助控股股东在定向增发中获利了吗？

考察了上市公司控股股东如何利用自媒体信息披露在定向增发融资中调节股价的变化,从而获取额外收益的过程。研究发现：控股股东为使定向增发融资顺利进行,倾向于在定向增发准备期频繁发布自媒体信息,以抬高股价吸引外部投资者关注,并且当发行对象不包括控股股东时,通过发布自媒体信息来抬高股价的行为会更加显著;而在定增新股定价期间,定向增发对象包括控股股东的上市公司却会显著减少自媒体信息发文数量,以压低股票价格,帮助控股股东以较低对价购入定增股票。进一步分析发现：上市公司中机构投资者持股对控股股东定价期间压低股价的行为具有显著抑制作用。从自媒体信息披露这一崭新视角切入,证实了我国上市公司控股股东在定向增发过程中既有通过自媒体信息披露使定向增发吸引关注、满足融资需求的动机,又有利用自媒体信息披露降低控股股东参与定向增发的成本、对自身进行利益输送的动机;而机构投资者能够有效监督这一过程中大股东的利己行为。研究结论为加强对上市公司在定向增发中信息披露的监管,保护中小投资者利益提供了有益的启示。     

终极控制股东、金字塔结构与会计稳健性

我国股权大都集中在大股东的手中,终极控制股东普遍采用金字塔股权结构的方式对底层公司实施控制并影响会计稳健性。基于Basu模型,采用2012-2017年深沪两市A股上市公司数据,对终极控制股东产权性质、金字塔股权结构对上市公司会计稳健性进行研究。结果表明:与终极控制股东为非国有的上市公司相比,终极控制股东为国有的上市公司会计稳健性更高;金字塔层级增加导致会计稳健性降低;金字塔层级的增加对于国有控股企业和非国有控股企业会计稳健性的影响存在差异,国有终极控制上市公司的会计稳健性更高。     

Corporate social responsibility and firm financial risk reduction: On the moderating role of the legal environment

Approaching the institutional environment through its regulative component, we distinguish between shareholder‐oriented and stakeholder‐oriented countries. Identifying first this classification with the distinction between common law versus civil law countries and using a large sample of 5,716 firm‐year observations that represents 1,169 individual firms in 25 countries between 2001 and 2011, we show that Corporate Social Responsibility (CSR) significantly reduces firms’ idiosyncratic risk in civil law countries but not in common law countries. Using then a more direct classification based on shareholder and employee protection scores, our findings suggest that CSR negatively affects firms’ idiosyncratic and systematic risks only in less shareholder‐oriented and more stakeholder‐oriented countries, respectively. These findings are similar in the different components of CSR with two notable exceptions: a high score in corporate governance reduces firm risk only in common law countries, and community involvement increases idiosyncratic risk in more shareholder‐oriented and less stakeholder‐oriented countries, respectively. Taken together, our results strongly support the view that the relationship between CSR and financial risk is moderated by the institutional context of the firm.     

对獐子岛股权激励方式的研究

獐子岛股东转让股份的股票激励计划是中国上市公司中首个采用此方法的中小板企业激励计划,这是一种具有创新意义的激励方式,它把股权激励和股份之间的转让有机结合在一起,促使管理层更加注重长期目标,有利于企业的长期稳健发展,对我国上市公司具有重要借鉴意义。但该计划也存在由于行权条件较低、激励方式单一等因素导致激励效果不明显等问题,这就为企业建立有效的公司治理结构提出了更高的要求。     

独立董事防范上市公司股东相容性风险的博弈分析

公司治理中不可避免地存在着股东间的矛盾与冲突,隐含了股东利益相容性风险.虽然独立董事制度理论上有助于该类风险的防范,但由于现实中的独立董事是有限理性的经济人,导致其实际发挥作用需要满足一定的条件,如果条件不满足或不充分,将直接影响这一理论功能的发挥.本文从博弈角度分析了独立董事制度在防范股东相容性风险方面应具备的条件,并据此提出了相关的建议措施.
