From Playground to Boardroom: Endowed Social Status and Managerial Performance

Description
By matching a CEO's place of residence in his or her formative years with U.S. Census survey data, I obtain an estimate of the CEO's family wealth and study the link between the CEO's endowed social status and firm performance. I find that, on average, CEOs born into poor families…

By matching a CEO's place of residence in his or her formative years with U.S. Census survey data, I obtain an estimate of the CEO's family wealth and study the link between the CEO's endowed social status and firm performance. I find that, on average, CEOs born into poor families outperform those born into wealthy families, as measured by a variety of proxies for firm performance. There is no evidence of higher risk-taking by the CEOs from low social status backgrounds. Further, CEOs from less privileged families perform better in firms with high R&D spending but they underperform CEOs from wealthy families when firms operate in a more uncertain environment. Taken together, my results show that endowed family wealth of a CEO is useful in identifying his or her managerial ability.

连续并购对公司长短期绩效的影响--以A股上市公司为例

Description随着我国资本市场的快速发展，连续并购成为上市公司实现市值提升的重要策略，然而对于连续并购是否能实现有效价值创造和市值增长，国内外文献研究均没有一致的结论。本文研究连续并购对上市公司短期和长期绩效的影响，并探究管理层过度自信现象和学习效应、公司股权性质和并购交易特征等对结果的影响，就企业如何更好的发挥连续并购价值创造功能，避免潜在风险等方面提出相应建议。利用国泰安（CSMAR）并购重组数据库, 本文以2010-2017年A股公司为研究样本，通过事件研究法发现，连续并购能带来正的超额收益(CAR)，但当连续并购阶次达到4阶时，市场反应明显变负。CAR随着阶次递增呈现下降趋势，证明了连续并购的财富递减效应。进一步地，本文发现首次并购成功带来的过度自信会导致高阶次并购绩效不断下降；管理层未经过充分学习和准备就进行的并购，会伤害公司短期绩效，并且可能阻碍公司更高阶的并购事件的发生。结果证明了管理者过度自信假说在A股市场的适用性，以及组织学习理论的部分解释能力。控制并购交易等因素后的多元回归结果和前述发现一致。 接下来，本文采用多元回归对连续并购长期绩效影响进行实证检验。在经营绩效方面，连续并购行为短期内不会产生明显负面影响，但随着并购的完成和新业务的开展，连续并购对经营业绩的负面影响逐渐凸显并显著，结果证实连续并购对公司长期经营业绩是有害的。交易特征变量、公司治理结构和财务状态一定程度上能够改善公司长期业绩。对于长期市场估值倍数，本文发现连续并购能够显著提升公司的市场估值倍数， 并且该正面影响随着并购的完成和新业务的开展不断增强。进一步探究发现，连续并购对经营绩效的负面影响只存在于国有企业，而连续并购对市场估值倍数的提升作用只存在于私有企业，从而解释了连续并购后经营绩效和市场化估值倍数结果相悖现象的出现。基于本文发现，文章最后向上市公司管理层的并购决策提出了相应建议。
