Structuring deals and governance after the IPO: Entrepreneurs and venture capitalists in high tech start-ups

In an effort to better understand the effects of venture capital investment on selected firm governance and financing structures, we examined the post-IPO experiences of 190 biotechnology and healthcare firms (see appendix). Our study revealed that in virtually all cases, the involvement of venture capitalists reduced the role of the founder-entrepreneur in strategic decision making. This was illustrated by the larger proportion of outside directors when venture capitalists invested and the smaller proportion of entrepreneurs who remained officers or in board positions after the IPO. We also found that venture capitalists rarely invested alone, and preferred to structure deals in which venture capital partners share both risks and rewards.     

Does reputation of sponsors matter in IPO? Evidence from Hong Kong

Contrary to other markets where underwriters perform a combined role of underwriting and sponsoring in an Initial Public Offering (IPO), IPO issuers in Hong Kong must appoint at least one sponsor in addition to the underwriters. The splitting of the single role of underwriters into two separate ones offers an ideal setting to disentangle the effects of the two roles and to examine which of the two roles—sponsor or underwriter—is more important in explaining IPO underpricing and initial volatility in the Hong Kong equity market. Interestingly, our findings provide supportive evidence that the sponsor reputation does matter in an IPO and it is even more significant than the underwriter reputation in explaining the IPO underpricing phenomenon. Given the recent high-tech fervor, our research goes deeper to examine specifically the role of sponsors on high-tech firms, with results indicating that the reliance on sponsors is higher for traditional issuers than for technology firms. We further discover that sponsors and underwriters are playing substitution roles rather than complementary roles. In order to examine the regulatory policy impact, our research also compares the role of IPO sponsors before and after the launch of the new sponsor regulatory regime in 2013. The empirical findings lend support to our argument that after the launch of the new regulations, public awareness of sponsors is raised, respect towards more reputable sponsor increases, and thus, the role of sponsors becomes more important than before.     

The path-to-profitability of Internet IPO firms

Extant empirical evidence indicates that the proportion of firms going public prior to achieving profitability has been increasing over time. This phenomenon is largely driven by an increase in the proportion of technology firms going public. Since there is considerable uncertainty regarding the long-term economic viability of these firms at the time of going public, identifying factors that influence their ability to attain key post-IPO milestones such as achieving profitability represents an important area of research. We employ a theoretical framework built around agency and signaling considerations to identify factors that influence the probability and timing of post-IPO profitability of Internet IPO firms. We estimate Cox Proportional Hazards models to test whether factors identified by our theoretical framework significantly impact the probability of post-IPO profitability as a function of time. We find that the probability of post-IPO profitability increases with pre-IPO investor demand and change in ownership at the IPO of the top officers and directors. On the other hand, the probability of post-IPO profitability decreases with the venture capital participation, proportion of outsiders on the board, and pre-market valuation uncertainty.     

The influence of people on the performance of IPO firms

Until the mid-1990s, the study of initial public offerings (IPOs) fell mainly under the purview of the finance literature. Within the last 10 years, however, management and entrepreneurship scholars have delved more into this subject area, as well. This article summarizes research examining IPO firms that has appeared in management and entrepreneurship journals, highlighting in particular the influence of individuals (namely executives and boards of directors) on IPO firm outcomes.     

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。     

中西公共服务市场化改革比较研究

公共服务市场化改革既是当代西方各国公共治理变革的共同趋势,也是中国行政改革的热点问题。中国公共服务市场化改革与西方国家既有相似点,也有很大的差别,通过中西比较研究可以为中国公共服务市场化改革提供有益的启示。     

中国住房公积金制度的问题及改革方向

《上海市住房公积金条例》的产生先于中国《住房公积金管理条例》。受制于劣质土地财政,住房保障并没有成为中国住房公积金制度的基本职能。中国的住房公积金制度既不反映保障性住宅的供给,也不反映保障性住宅的需求。中国住房公积金某种程度上不是住房保障基金,而是住房储蓄资金。城市劳动力价值支持基础上的保障性住宅供求衔接是中国《住房公积金管理条例》的改革方向。

中国与东盟10国双边农产品贸易流量与贸易潜力的分析——基于贸易引力模型的研究

贸易引力模型是对国际贸易进行实证分析的重要方法。本文以传统引力模型为基础,并结合中国与东盟国家的实际情况建立模型,定量分析中国与东盟10国农产品贸易的状况。通过对模型的实证检验,得出影响中国与东盟10国双边农产品贸易流量的因素主要有GDP总量、人口数量、空间距离和制度安排等。在此基础上预测了中国与各国的贸易潜力,得出中国与东盟多数国家之间存在"贸易不足",认为双边农产品贸易发展潜力巨大,并提出了相应的政策建议。
