FUNCTIONAL FORMS OF THE CAPITAL ASSET PRICING MODEL UNDER DIFFERENT MARKET RISK REGIMES

This paper demonstrates that, given the assumption that asset returns are generated by the linear market model, the same functional form for the capital asset pricing model can be derived via the simpler linear programming approach for the riskaverse, risk-neutral, and risk-loving market regimes.     

诚信是资本市场立命之本

经过二十年的飞速发展,中国资本市场发生了深刻的变化,先后构建了主板,中小板,创业板,产权交易市场等多种交易平台,股市在资源配置,价格发现等方面的功能得到了更有效的发挥。尤其是2005年5月股份制改革之后,一系列长期困扰资本市场发展的体制性障碍被逐渐破除,中国股市进入了全流通时代。短短几年的时间里,A股流通市值增加了四倍多,上市公司增加至两千多家。可以说,我国已初步建立了按照市场规律运行的市场,具备了发展多层次资本市场的实力。     

MARKET EXPECTATIONS AND THE VALUATION EFFECTS OF EQUITY ISSUANCE

We examine how the wealth effects of equity offers are influenced by investors' expectation of the equity type (public or private) to be issued. Firms deviating to the public market may be issuing when information asymmetry or agency costs are high, and their wealth effects are more negative than for firms that are anticipated to issue equity publicly. Firms deviating to the private market, however, may signal firm undervaluation or monitoring benefits and experience more positive wealth effects than firms that are expected to issue equity privately. For the private issues, public market accessibility appears to influence the wealth effects.
