IPO、公司治理与企业价值——资本成本视角的理论综述

本文认为,首次公开发行上市(IPO)是企业生命周期中的里程碑。企业IPO行为改变了公司资本结构,通过资本结构对公司治理发生积极作用(融资机制、价格机制和并购机制),使得公司治理在经营者激励、信息披露、投资者保护等方面得到改善将提升企业价值,进而实现企业价值最大化的理财目标。

IPO performance and the size effect: Evidence for the US and Canada

This study provides new evidence on the interaction between firm size and IPO underpricing in the US and Canadian markets. We find a size effect on IPO underpricing in both Canada and the US, which is larger for Canadian firms. Canadian small firms show more underpricing than US small firms (19.32% vs. 13.87%). Large Canadian firms also exhibit more underpricing than their US counterparts over the sample period (12.83% vs. 10.09%). A size effect on performance is not apparent for holding periods beyond six months from the IPO in both countries, consistent with seasoning effects that reduce information asymmetries across firms over longer investment horizons.     

Third-party certification and post-IPO acquisitions

ABSTRACT

We explore the link between third-party certification (venture capital backing, analyst following and having a top underwriter), and post-IPO acquisition activity through the reduction in valuation uncertainty channel. In a sample of 2,424 U.S. IPOs, we find that third-party certification facilitates post-IPO acquisitions. The certified firms are both more likely and conduct acquisitions sooner after the IPO. Our results support the notion that third-party certification reduces post-IPO valuation uncertainty and thereby facilitates a more efficient acquisition strategy.     

超宽带能量检测接收机的设计研究

根据PPM调制方式的特点和实际接收到的超宽带脉冲信号波形的特征,为了在超宽带通信中,简单、快速地接收信号,文章采用基于能量检测的接收机方案,用门控能量检测电路来代替时域相关器,将射频检测与同步捕获相结合实现快速捕获同步。实测数据验证了此接收机方案在100Mbps高传输速率的情况下能取得较好的超宽带信号接收效果。该方法在提供了良好的超宽带信号接收效果的同时,简化了接收机射频端电路的复杂度,减少了接收机同步捕获所需的时间。

技术创新与企业IPO后绩效表现

企业技术创新一直以来都是学术界研究的热点,对企业生产经营、行业竞争以及发展战略发挥着重要作用。传统企业技术创新衡量方法研究在IPO后绩效表现方面存在不足。研究发现,企业IPO决策过程中IPO时机与特征可以反映其技术创新动机,进而可基于技术创新角度对企业IPO后绩效表现作出合理解释。通过构建技术创新评价指标,对比分析了技术创新企业与非技术创新企业在IPO后长期绩效表现的异同点。结果表明：①技术创新动机与企业IPO后财务绩效正相关,技术创新强的企业在后市仍能保持良好业绩;②技术创新企业的长期市场表现看涨,而非技术创新企业则呈现波动;③技术创新企业存活质量明显高于非技术创新企业。     

中国A股市场IPO抑价影响因素的实证研究

IPO抑价是全球资本市场的普遍现象,是一级市场定价效率低下和二级市场交易不规范的具体表现。IPO抑价使得资本市场资源配置效率低,同时也会产生众多金融风险。在中国IPO抑价率过高,普遍达到100%以上,超过了国外成熟市场和很多的新兴市场。在对国内外相关研究进行综述之后,再构建模型引入实证分析,对理论在国内的适用性进行研究进而探寻导致IPO抑价的原因。信息不对称是导致IPO抑价的主要原因,同时承销商声誉、公司信号、资本市场羊群效应也有一定的影响。     

Can governance help in making an IPO “successful”? New evidence from Europe

This paper investigates the determinants of a “successful” IPO from a corporate governance perspective upon a representative sample of European listings from 2000 to 2015. We use an extensive dataset of market performance, financial data, and corporate governance characteristics to run the investigation. Differently from previous studies, our analysis embraces both a short‐term perspective and a medium–long‐term perspective, where the board of directors seems to perform different tasks, moving from a value creation to a value protection strategy. Among the others, we find that board size, board independence, and their qualifications, together with their experience in other boards, are associated with a positive performance of the IPO in a short‐term horizon and in the medium–long‐term period, although significant differences emerge among those time perspectives.
