The private equity business model and associated strategies for HRM: evidence and implications?

Are private equity firms significant actors in the UK market for corporate control? Do they represent a new organizational form befitting a new business model? What are the direct and indirect pressures on management that flow from the diffusion of this business model and its associated organizational form? In terms of human resource management does acquisition by private equity have a significant or negligible effect? This paper looks at the development and diffusion of private equity and the ‘take private’ private equity business model (PEBM) and the effects of these on the management of HR. In addition to this the paper evaluates the PEBM within comparative institutional approaches to international business and HRM.     

第一大股东性质、董事会领导结构与公司绩效

通过对2010年A股上市公司的实证研究,从第一大股东视角研究不同的董事会领导结构安排对公司绩效的影响。研究表明,当第一大股东对公司控制能力较强时,两职合一与公司绩效负相关,而控制能力较弱时,两职合一与公司绩效正相关。本文还根据第一大股东所有权性质的不同进行分类研究,发现当公司第一大股东为非国有股股东时,由董事长分任总经理更有助于改善公司绩效。     

基于经济波动的控股股东与股利政策关系研究——来自中国证券市场的经验证据

文章考察了控股股东和经济波动对上市公司股利政策的影响.结果表明,从控股股东的角度来看,第一大股东持股比例越高,公司越愿意支付股利,尤其是现金股利.当考虑了经济波动的影响时我们发现,在经济下降期,公司不再愿意支付股利,即使支付股利,公司也偏向于支付股票股利.此外,不同股权性质的公司在经济波动期的股利政策也不一样.在经济下降期,非国有控股公司第一大股东比例越高,股票股利支付数量越少,现金股利支付数量越多,但是,国有控股公司这种变化并不显著,说明相对于国有控股公司,非国有企业的股利政策更容易受到经济波动的影响.     

股权结构与控股股东行为的实证研究

关于股权结构与控制权收益实证分析表明,第一大股东持股比例越高,控制权收益越高;第二大股东与第一大股东之间的相互制衡有利于限制控股股东的掠夺行为,减少控制权收益。因此,降低股权集中度、充分发挥大股东之间的相互制衡作用是规范控股股东行为的关键所在。

中小股东近乎全部出席股东大会的公司治理模式

只有小部分中小股东参加股东大会,客观上将公司的经营管理委托给控股股东,中小股东付出了巨大的委托成本,导致他们亏多盈少。通过创新制度：在出席股东大会的中小股东当中,由他们选举若干名＂补全代表＂,由这些＂补全代表＂行使未出席股东大会股份的表决权,中小股东近乎全部参加股东大会;中小股东以其持股总量按每5%持股量选派一名董事,每一位大股东分别以每5%持股量直接派出一名董事,董事会中既有控股股东的代表又有中小股东的代表,控股股东与其他股东相互约束并制衡,框架出一个全体股东同生共死、同等收益的治理模式。     

大股东控制:利益协同效应还是壕沟防御效应—基于中国上市公司的实证分析

以2001—2005内地上市公司为对象,通过面板数据实证检验大股东控制和公司价值的关系,我们可以发现,大股东控制和公司价值呈倒U型关系。这种倒U型关系对控制人的性质敏感,但对产品市场竞争不敏感。在中国的制度环境下,公司治理和产品市场竞争不存在替代效应。     

大股东控制与盈余管理行为研究:来自配股公司的证据

在上市公司配股融资过程中,大股东具有通过盈余管理来获得配股资格和提高股票价格的强烈动机。本文以1998—2002年间456家实施配股的上市公司为样本,基于行业横截面数据和修正的Jones模型研究了配股融资过程中盈余管理的分布特征,并分析了大股东控制对盈余管理行为的影响。研究结果表明：（1）上市公司在配股前3个年度和配股当年存在显著的盈余管理机会主义行为;（2）配股公司的盈余管理程度与第一大股东持股比例具有倒u型关系：当第一大股东持股比例低于53．20％时表现出正相关关系,而当第一大股东持股比例高于53．20％时则表现出负相关关系;（3）盈余管理程度与前2—10大股东持股集中度、负债比率和资本支出水平之间具有负相关关系．而与管理层持股比例和公司规模之间具有正相关关系。大股东通过盈余管理实现了对小股东财富的掠夺效应。造成了上市公司价值、声誉和后续融资能力的下降。     

The reaction of firm ex ante cost of equity capital to the resolution of shareholder class action lawsuits

Existing research provides evidence that providers of capital (banks, public debt, and equity) all increase the expected return on securities after the initiation of a shareholder lawsuit. Many of these lawsuits are dismissed or settled with trivial monetary penalties, which suggests that an across-the-board permanent increase in the cost of capital is misguided. After estimating the probable outcome of a shareholder lawsuit using only information available at the time the shareholder lawsuit is filed, we study the resolution of shareholder lawsuits to determine if market participants adjust their expected return after a case is resolved. We find an increase (decrease) in the ex ante cost of equity capital when there is a surprise settlement (dismissal), which is consistent with an efficient market. Further, we present evidence consistent with equity market participants monitoring the progress of shareholder lawsuits prior to resolution. Overall, our results suggest that firm ex ante cost of equity capital only changes after the resolution of a shareholder lawsuit if the outcome of the case is different than initially predicted.
