上市公司中小投资者权益保护制度绩效的实证检验

我国上市公司终极控股股东利用对上市公司的控制权,普遍通过非公平关联交易、违规信息披露、市场操纵等方式获取控制权私人收益,非法侵害中小投资者的合法权益。从上市公司股权结构等角度,通过逻辑回归分析,分别对股权分置改革时期、后股权分置时期中国上市公司中小投资者权益保护制度的绩效进行实证检验,这为制定保护中小投资者权益的政策提供了实证依据。     

非流通股价值、股改对价与解禁股减持回报

本文以2002—2006年A股非ST类上市公司的388笔非流通股交易为研究对象,得出以下主要结论:第一,非流通股转让价格仅仅是当日非流通股交易价格的0.336;非流通股转让价格相对于流通股价格的比率受非流通股比例的负面影响;第二,此轮股权分置改革对价大多集中于10送3.07股,远低于合理送股对价水平,实际送股数量难以保证流通股股东的合理经济利益。进一步的分析也表明,股改前非流通股比例、非流通股转让价格比例是影响大小非套现回报率的重要因素。     

Stock options,restricted stock,salary, or bonus? Managing CEO compensation to maximize organizational performance

CEO pay has gone through remarkable changes over the past two decades. The most striking new features have been the increased use of stock options in the early 2000s, and of restricted stock since then. Both forms of stock-based compensation are intended to resolve the agency problem that occurs when CEOs do not act in the best interests of stockholders, but each has its advantages and limitations. In this instalment of Organizational Performance, we discuss the history of their use and similarities and differences between the two, and argue that both are often overused. Bonuses based on strategic goals, on the other hand, may be underused. We conclude with a contextual approach to guide boards of directors in making choices among the forms of CEO compensation—stock options, restricted stock, salary, and bonus—to incentivize CEOs to work toward maximizing organizational performance. Briefly, stock options are most appropriate for growth firms, and restricted stock for stable firms. Both forms of stock-based compensation are more appropriate for new than for long-tenured CEOs.

Time-varying Informational Efficiency in China's A-Share and B-Share Markets

This paper employs a time-varying framework to examine the informational efficiency of China's A-share and B-share markets, with a focus placed on the following issues: changing weak-form efficiency, the leverage effect, and information transmission in return volatility. We find that the A-share markets perform better than the B-share markets in terms of efficiency-improving; significant leverage effects exist in three of four markets but with different signs; and no weak and strong volatility transmissions characterise different pairs of markets. Market segmentation is also documented, as evidenced by no co-movements in the long-run behaviour of the four Chinese share markets.     

上市公司限售股转让税收政策研究

自2010年1月1日实施对个人转让限售股征收20％的个人所得税以来，通过法人转股给自然人进行避税的方式不再有效，但是各种新的避税方式仍层出不穷。对当前限售股转让的避税方式及其制度根源进行深入探讨，可以进一步完善当前税收政策的对策，使其充分发挥税收调节收入分配的职能。     

Economic conditions and the motives for multiple open-market share buybacks

We examine the impact of business conditions on the frequency of share repurchases. The results generally indicate that share repurchase programs are positive and statistically significant in HIGH economic states relative to the other economic states. Segmenting the data into frequency of repurchases, we find evidence suggesting different economic states exert influence on frequent and infrequent but not occasional repurchase programs. Further, we show that firms that institute frequent share repurchasing programs experience stronger returns across different business cycles compared to infrequent and occasional share repurchasers.     

全球经济失衡与美元的国际地位

全球经济失衡主要表现为美国长期的、高额的经常项目逆差和中国等亚洲国家的持续经常项目顺差。一些经济学家担心美国持续的经常项目逆差会导致美元的国际地位下降,并将最终导致世界经济增长率的下降。本文通过分析5种储备货币的面板数据得出结论:美国的经常项目逆差的确会导致美元的国际地位下降,但是这种影响却很微弱;对美元国际地位影响最大的因素是衡量网络外部性的变量,这意味着人们的习惯是决定美元国际地位的最主要因素。鉴于以上分析,我们认为美国当前的经常项目逆差还不足以对美元的国际地位产生大的影响。     

大小非解禁和股价波动关系的实证分析

本文基于2007年1月至2011年3月的月度时间序列样本,构建了经典的多元回归模型,对"大小非"解禁与股价走势之间的关系进行了分阶段实证研究。计量结果表明,国内国际经济形势、货币政策以及预期等因素才是影响我国股价走势变化的最主要因素,而"大小非"解禁对股价走势的影响程度则要受到我国股市所处行情阶段的限制。     

网上新股申购中的资金规划研究

网上新股申购通常被认为是风险较低而收益稳定的投资策略。由于新股投资机会较为密集且短期占用资金较多,面对多个申购机会的合理取舍及资金的高效使用将显得尤为重要。通过将新股申购问题抽象为一般连续投资下的资金规划问题,给出其约束方程,指出其求解方法,然后讨论了新股申购在两种目标下的资金规划,并与未做资金规划的简单方案进行比较,结果显示该方法有效地达到了规划目标,提高了整体收益。
