IPO初始回报与创业投资参与的研究——基于我国创业板的实证研究

本文在论述国际学术界关于创业投资在企业IPO中作用理论研究的基础上,通过采用实证分析方法,对我国创业板上市的153家公司2007—2009年的数据进行研究,得出如下结论：企业IPO初始回报与是否有创业投资参与具有显著的正相关关系。同时,IPO初始回报与公司规模显著负相关,与股份发行比例显著负相关,与公司上市时年龄显著负相关,与企业上市日的上证指数收益率显著正相关,与净资产收益率显著负相关。     

IPO抑价和市场化程度——基于中国东西部上市公司的比较研究

中国东部和西部地区的市场化程度存在显著差异,这为研究市场化程度对IPO抑价率的影响提供了难得的天然环境。笔者以1998年～2007年间来自于东部和西部地区的580个IPO为研究样本,实证分析了市场化程度在IPO抑价率形成过程中的作用,得出研究结论:市场化程度对IPO抑价率产生了负向的显著影响,该研究结论具有稳健性。依据该结论提出了相应的对策建议。     

The Effects of Public Venture Capital Investments on Corporate Governance: Evidence From IPO Firms in Emerging Markets

This study examines the impact of public venture capital (hereafter PVC) investments on corporate governance of initial public offering (hereafter IPO) firms in emerging markets. Using data collected from Taiwan PVC investments during 1996–2005, we analyse three corporate governance features in IPO firms: earnings management, board characteristics, and excess control by controlling shareholders. We find that PVC‐backed firms use fewer accounting accruals in their IPO financial statements than non‐PVC‐backed firms. This result suggests that PVC‐backed IPO firms engage in less earnings management than non‐PVC‐backed IPO firms. We also find PVC‐backed firms tend to set up their boards with fewer non‐independent directors and supervisors at IPO. This result indicates that PVC‐backed IPO firms have better board structures than non‐PVC‐backed IPO firms. Finally, we find that controlling shareholders are less likely to exert excess control in PVC‐backed firms than in non‐PVC‐backed firms. Overall, our results indicate that PVC investments add value to new IPO firms not only in financing their capital needs but also in creating better corporate governance structures in emerging markets.     

Are venture capitalist-backed IPOs more innovative? Evidence from an emerging market

This study examines whether venture capital (VC)-backed IPOs are more innovative than otherwise equivalent non-VC-backed IPOs. Using manually collected R&D records from annual reports and patent data from the Chinese State Intellectual Property Office (CSIPO) from 2007 to 2012, we find that VC-backed IPOs have higher R&D expenditures and more patents granted in the three years after IPOs. More specifically, they have more invention, application, and design patents in post-IPO. We use a two-stage instrumental variable, propensity score matching, difference-in-differences approach to mitigate selection biases and find our results to be consistent with our hypothesis. We conclude that VCs can positively influence IPO firms to increase R&D expenditures and innovative output levels in China. In addition, we document that the government ownership adversely affects innovation of VC-backed firms. Policy implications are discussed.     

Signaling in science-based IPOs: The combined effect of affiliation with prestigious universities,underwriters, and venture capitalists

This paper studies the combined effect of affiliation with prestigious universities, underwriters, and venture capitalists on the valuation of biotech ventures at IPO and their post-IPO performance. We argue that affiliation to a prestigious university provides the affiliated firm with a quality signal in the scientific domain. The pure quality signaling effect of the affiliation is isolated from the substantive benefits it provides by performing a difference-in-difference approach based on the scientific reputation of scientists in firms' upper echelons. The signal is stronger the weaker is the scientific reputation of scientists of the focal IPO-firm and is additive to those provided by prestigious venture capitalists and underwriters. Results for a sample of 254 European biotech ventures that went through an IPO between 1990 and 2009 confirm our predictions.     

Country-level Accounting Enforcement and IPO Underpricing

Using a sample of up to 2,503 initial public offerings (IPOs) in 32 countries from 2011–2017, we predict and find that higher levels of country-level accounting enforcement are associated with lower levels of IPO underpricing. IPOs in countries with a relatively low accounting enforcement score (second quintile) exhibit a mean underpricing of 19%, whereas the mean underpricing amounts to just 9% in countries with a relatively high score (fourth quintile). The results remain qualitatively the same when we employ a multi-level model or a difference-in-difference design. In countries that substantially strengthened their accounting enforcement in the 2003–2009 period, the level of IPO underpricing decreased significantly. We show that accounting enforcement matters for the cost of going public.     

IPO first‐day returns: Skewness preference,investor sentiment and uncertainty underlying factors

In this paper, we investigate the initial public offering (IPO) first-day returns. Our focus is to examine the irrational component of the agent behavior towards IPO lotteries. Based on 234 French IPOs performed between 2002 and 2012, we find that IPOs with high initial returns have higher idiosyncratic skewness, turnover and momentum. This finding provides empirical evidence for investors' preference for stocks with lottery-like features and investor sentiment. In addition, we show that the skewness preference and the investor sentiment effect are stronger during periods of favorable market conditions. Our results are robust to the integration of uncertainty underlying factors.     

Noise from online discussion forums: Evidence from IPOs in China

In this study, we use initial public offerings (IPOs) in China to investigate how online stock forums influence information asymmetry and IPO valuation. The empirical analysis isolates the underpricing and overvaluation components of initial returns. The number of forum comments, postings, and readings are positively associated with initial returns and the degree of underpricing, implying that forums create noise that exacerbates information asymmetry during IPOs. This effect is amplified by the quiet period regulation, which drives investors to rely on online discussion forums to obtain information. Through sentiment analyses of forum posts and media coverage, we find that the negative effect of online forums is more prominent when bad news prevails. We clarify the role of online stock forums in IPO pricing and information asymmetry by separating underpricing from overvaluation in initial returns.     

I am therefore I own: Implications of organization-based identity for employee stock ownership

Most research on employee stock plan participation investigates the effects of such forms of ownership on employee attitudes, leaving our understanding of the individual differences that contribute to employee ownership largely unknown. Drawing from the consumer behavior literature, our study explores the effect of organization-based identity on the decision to participate in an employee stock purchase plan. The study was conducted in a newly public firm where we examine the effect of organization-based identity on the purchase decision in two time periods. The first point in time was the initial public offering (IPO), when the employee has little information on how the firm's stock will perform in the market. The second point in time was the first quarter following the IPO, when employees have market data to help them with decision-making. Results indicate that, as predicted, organization-based identity is associated with participation in an employee stock purchase plan, at both points in time, above and beyond the influence of several economic and psychological predictors reported in prior studies.     

Initial public offer pricing,corporate governance and contextual relevance: Australian evidence

This study examines the relationship between initial public offer (IPO) corporate governance, IPO pricing and possible contextual relevance. A comprehensive inventory of IPO governance attributes is modelled. A positive association is reported between the inventory and IPO initial returns. This relationship is attenuated for IPOs where a diminished price relevance of governance structure is posited: smaller scale firms and/or those with alternative monitoring agents in place. Relevance appears modified and even supplanted by particular corporate priorities or the presence of other monitoring mechanisms. These contexts inform the motivation of key players regarding whether and how to act in response to the governance signal.
