风险资本IPO退出方式的信息经济学分析

风险资本退出方式以IPO为较理想模式.风险资本IPO退出方式存在着信息不对称,导致高质量风险企业退出风险资本市场、低质量风险企业充斥风险资本市场.通过信息传递模型的分析,得出在完全信息条件下高质量风险企业与低质量风险企业的市场分离均衡,从而实现风险资本的有效配置.要解决我国风险资本市场信息透明度的问题应从风险资本市场的完善、风险投资机构的建设以及政府服务职能和监管职能的健全三个方面入手,以实现风险资本市场的帕累托最优.     

IPO限额配给机制探讨：一个基于股权结构的分析

在所有权与控制权分离或部分分离的情况下，公司内部会出现代理问题．公司在上市之初安排大股东持股比例即确定公众持股量是解决代理问题的重要举措。本文分析了在信息不对称、合约不完全以及资本市场规制约束下不同IPO机制对公司股权结构的影响，探讨了限额配给机制的含义，并指出我国新股发行中存在的问题及解决方法。     

中国IPO市场存在承销商托市吗

本文采用修正后的Ruud(1993)收益率分布检验法对中国A股市场上IPO股票上市后短期收益率分布进行了检验.考虑抑价极大值会使样本收益率分布明显右偏,本文运用剔除抑价极大值后的样本对不同定价机制下的IPO后市短期收益率分布进行了正态性检验.我们发现,IPO股票上市后的短期收益率分布不能拒绝正态分布的零假设.这说明中国IPO市场不存在明显的承销商托市,目前高抑价的原因不能用承销商托市行为来解释.     

我国IPO定价合理性的实证分析

通过IPO抑价程度以及把抑价程度与成熟市场进行比较来判断IPO价格合理性,这种方法并不适用于我国股票市场。为此,文章利用价值变量提取的主成分因子分析了我国股票IPO定价的合理性,并通过对各阶段的实证分析检验了发行定价制度改革的效果。研究表明,总体而言我国股票IPO发行价格较市场价格更能反映公司内在价值,造成IPO抑价程度过高的主要原因是二级市场价格虚高;市场化定价试行阶段之所以没有得到理想的效果,可能是与市场化选择的时机有关,而不在于市场化定价制度本身。     

The development of capabilities in new firms

This research explores evidence of corporate capabilities for conducting acquisition and alliance deals in young firms. We hypothesize that investors conjecture about the future based on information about a firm's capabilities. Each successive deal carries intrinsic value, creates experience, generates feedback, and yields information about the firm's underlying capabilities. We evaluate whether stock prices impute expectations that firms will capably pursue particular programs of acquisitions and alliances. The analysis covers how investor responses change across successive deals on the theory that firms with a concentrated program of deals may develop capabilities more intensively than those with programs that involve both acquisitions and alliances. The dataset covers the population of firms that went through an initial public offering (IPO) in the United States between 1988 and 1999. It contains information on all of their post‐IPO acquisitions and alliances, and on how their stock prices changed in response to the announcement of each deal. The results suggest that within the first year after IPO, investors expect firms to execute particular streams of alliances and acquisitions that reflect their unique histories of demonstrated capabilities. We also find evidence that investors cannot fully anticipate deal programs. The findings support a capabilities‐based view of the firm and also show that accurate inference using event‐study methods may require digging deep into the early histories of firms.

Study on Chinese companies＇ perception on overseas public listing

This paper reports an investigation on Chinese companies＇ perception on overseas public listing. The investigation is mainly based on a questionnaire survey. The result shows that Chinese companies overwhelmingly accept overseas listing as a preferred option, which may shed some light on other Chinese companies in their evaluation on seeking overseas public listing as a strategic option to the overseas exchanges in their efforts of wooing the Chinese market.     

IPO pricing: a case of short-sale restrictions and divergent expectations

Prior research shows that short-sale restrictions during an IPO lead to higher aftermarket prices. Using this and heterogeneous expectations on the factor pricing coefficient, our model sheds additional light on the impact of the short-selling constraint. Like prior research, short-sale restrictions in the IPO market lead to higher aftermarket prices. Importantly, our model predicts that this constraint leads to a different factor pricing coefficient than the analog under complete markets. Our empirical tests over an extended period of time support the model's predictions.

Market Underreaction to Free Cash Flows from IPOs

I examine the relation between initial public offering (IPO) long‐run stock performance and the amount of cash raised by the firm in the offering. I find that IPOs raising more cash have poorer long‐run performance. The result is robust to different measurement methods. The evidence suggests that the market underreacts to free cash flow related agency problems in IPOs. Consistent with this interpretation, I find that IPO long‐run performance is more sensitive to the new cash raised in the offering if an IPO firm has lower capital expenditure or higher opening bid‐ask spread.     

我国股票上市首日超额收益影响因素的实证研究

在股权分置改革的背景下,运用多元线性回归模型的加权最小二乘法,对2004年1月1日至2006年12月31日期间发行上市的167只A股股票的实证研究,发现发行价格、上市首日股票换手率、筹资规模、发行市盈率以及市场指数等因素对上市首日超额收益具有重要影响,而发行前每股净资产、发行后实际流通股比例、发行方式及股权分置改革等因素对上市首日超额收益影响不明显。
