并购的长期财富效应--经验分析结果与协同效应解释

文章分析了并购对目标公司的长期财富效应,认为目标公司在并购后5年获得了巨大的超额收益.并购溢价可以解释目标公司的长期财富效应,并购溢价越高,并购产生的协同效应越大,目标公司的长期财富效应也越大.另外,并购后目标公司在组织形式和产权性质上的变化也会提高公司治理效率,从而增加目标公司的长期财富效应.     

IPO重启首日超额收益实证研究

重启之后的中国证券市场,是否能有效地消除各种弊端,抑制首日超额收益过高等异常现象？文章选取我国IPO重启以后发行的新股作为样本,从信息的不对称、承销商的声誉、我国特殊的新股发行制度以及我国投资者的情绪四个角度对我国IPO重启首日超额收益现象进行实证分析,并力图从一级市场发行价格确定和二级市场交易价格形成两个环节来解释我国的IPO首日超额收益,提出一些建设性的参考意见,促进我国的上市公司对IPO进行合理定价,优化资本市场资源的配置。     

虚拟品牌社群社会资本能影响消费者溢价购买行为吗？

重庆市委党校(重庆行政学院);中央党校(国家行政学院);摘要本文以虚拟品牌社群社会资本为研究对象,考察其与消费者溢价购买行为之间的关联性及其影响路径。构建了消费者溢价购买行为与虚拟品牌社群社会资本各维度的影响假设模型,并讨论了各维度之间的中介效应。研究发现:消费者信息价值感知通过社会资本各维度影响溢价购买行为,消费者社会价值感知通过结构性维度和认知性维度影响溢价购买行为,社会价值感知在关系性维度上对消费者溢价购买行为不具有显著影响。研究还发现了消费者对大宗耐用消费品与低价快速消费品在溢价购买行为中的差异规律。研究建议:大宗耐用消费品的企业需要在品牌社群运营中引导成员开展"体验性知识"的分享;企业在虚拟品牌社群运营中需要改善社会价值感知;企业应聚焦虚拟品牌社群的社会资本培育,获取溢价定价权,从而提升企业利润。     

海归董事降低了跨国并购溢价吗？——基于沪深A股上市公司的经验证据

基于高阶梯队理论,以2009—2017年沪深A股上市公司跨国并购交易为样本,实证分析海归董事对跨国并购溢价的影响。研究结果表明：具有海外学习、工作经历的海归董事具有特有的信息优势和关系资源,在跨国并购定价过程中可以有效发挥咨询功能,显著降低了并购溢价;海归董事对跨国并购溢价的抑制效应在更大的国内市场竞争、国有企业、并购目标涉及资源与通信类等敏感性行业中更加显著。进一步分析发现,与海外学习背景相比,海归董事的海外工作背景能够对跨国并购溢价发挥更大的边际作用,并且只有外部海归董事才会对跨国并购溢价产生抑制作用。     

Market Timing and Internationalization Decisions: A Contingency Perspective

Does acquisition of low‐cost capital through market timing improve the likelihood of a firm's internationalization? Under what circumstances will the above relationship be stronger? These questions are the focus of our study. We integrate the arguments of the resource‐based view and the market timing theory to answer these questions. We constructed a sample of capital‐raising moves and international investments by 905 listed Chinese firms spanning the 1992–2012 period. Based on random‐effects regression analyses, we find that firms deploying market timing are indeed more likely to internationalize. We also find that this effect is stronger for initial entries than subsequent expansions in a country.     

Capital–Skill Complementarity: Does Capital Composition Matter?

We estimate the effect of capital composition on the size of capital–skill complementarity and the skill wage premium. Disaggregating the capital stock into different types according to technological content, we find that: capital is more of a q‐complement to skilled labor than to unskilled labor; the higher the technological component of capital, the larger the size of the relative q‐complementarity between capital and skilled labor; and replacing non‐technological with technological capital might increase the skill wage premium by about 9 percent. Our results highlight that changes in capital composition matter for understanding changes in the skill wage premium.     

Changes in Occupational Tasks and Their Association with Individual Wages and Occupational Mobility

This study provides novel evidence on the relevance of task content changes between and within occupations to wage dynamics of occupational changers and stayers. I use individual‐level, cross‐sectional data featuring tasks performed on the job to compute a measure of proximity of job contents. Then, I merge this measure to a large‐scale panel survey to show that occupational changers experience a wage growth that is declining when the accompanying alterations in task contents are big. For occupational stayers, alterations in task contents generate a positive wage component, beyond tenure effect. However, the results are not robust with respect to the choice of proximity measure and over time.     

Does investor sentiment affect fund crashes? Evidence from Chinese open-end funds

This paper aims to detect the impact of investor sentiment on the open-end fund crashes, drawing on the open-end stock funds and partial stock funds of China for the 2009–2019 period. The results show that the rise of investor sentiment will significantly increase the risk of the open-end fund crashes, which remains valid after robustness tests. Further researches indicate that the market timing and stock selection abilities of fund managers weaken the positive impact of investor sentiment on the open-end fund crashes, and the market illiquidity promotes the positive impact of investor sentiment on the open-end fund crashes.
