股权激励对上市公司投资效率的影响

本文以2006-2014年沪深两市上市公司的数据为样本,考察了股权激励对上市公司投资效率的影响。进一步分析了在不同货币政策背景下股权激励对投资效率的影响效果是否相同。结果发现,上市公司实施股权激励计划没有提高反而降低了上市公司的投资效率;股权激励在货币政策宽松期对投资效率有消极影响。研究结论提出了关于股权激励如何影响投资效率的新认识,对上市公司制定科学合理的股权激励计划也有一定的借鉴意义。

对上市公司经营者股权激励的考察分析

在激励机制设计不当或公司内部治理弱化的情况下对经营进行股权激励，不仅不能起到激励经营像关心自己的利益一样真正关心企业利益的作用，相反，会“名正言顺”地沦为经营掠夺股东利益为自己谋利的工具。     

商业银行股权激励的特殊意义与现实问题分析

银行业普遍存在的管制,使银行面临着有限的控制权市场和接管威胁,从而大大降低了市场约束银行管理者的能力,因此对银行而言,通过股权激励机制协调股东和管理者的利益、降低代理成本显得尤为重要.我国商业银行实施股权激励不应盲目照搬西方国家的范例,应慎重选择股权激励的实施范围,目前最好只局限在高级管理人员,通过对股权激励机制的合理设计来充分发挥其长期激励效应,切不可盲目扩大激励范围,将股权激励演变成一种新的福利措施.应尽快建立起以经济资本为核心的业绩考核体系,在经济资本的约束下实现业务发展模式和盈利模式的转变.股权激励机制的有效实施离不开完善的银行治理结构.     

Time-Limited Property Rights and Investment Incentives

Although it is axiomatic that property rights of infinite duration are necessary for owners to make efficient long term investments in their property, time limits on property rights are pervasive in the law. This paper provides an economic justification for such limits by arguing that they actually enhance property values in the presence of imperfect information. In so doing, the analysis offers a coherent approach for understanding what otherwise appear to be unrelated doctrines in the law.     

Highly Valued Equity and Discretionary Accruals

Abstract:  Overvalued equity provides a strong incentive for managers to report earnings that do not disappoint the market (  Jensen, 2005 ). We find that this can be extended to highly valued equity more generally. In the year following the classification as highly valued and compared to firms with less extreme valuations, highly valued firms have significantly higher discretionary accruals and exhibit a more pronounced positive association between discretionary accruals and proxies for the likelihood of failing to meet earnings targets. These findings are consistent with the use of discretionary accruals to manage earnings in support of extreme valuation. Because highly valued equity will likely result in CEOs with valuable stock and stock option portfolios, we test whether and show that the overvalued equity incentive is incremental to a CEO's equity portfolio incentive. One implication is that directors and audit committees should be especially on guard for possible earnings management when a firm has extremely high valuation multiples and when the CEO has a lot of equity at risk.     

Investment Opportunities and the Relation Between Equity Value and Employees' Bonus

A sample of firms where employee stock options and other long‐term incentives are absent but an annual bonus is required is examined. A positive relation is found between firm equity value and stock bonus but not cash bonus. The positive relation is stronger when the firm has greater investment opportunities. Additionally, the relation is shown to be nonlinear in the sense that the marginal effect of stock bonus on equity value is positive but decreasing (negative) when the stock bonus is below (above) the breakpoint. Overall, the annual stock bonus is valued positively by investors even though it is linked to the firm's contemporaneous but not future performance.     

Equity Fund Performance Persistence with Investment Style: Evidence from Korea

Using a comprehensive database on equity funds in Korea, we investigate the performance and performance persistence with investment style employing the Fama and French three-factor model and the Carhart four-factor model. The paper finds that most investment styles in Korea noticeably outperform the passive benchmarks. In addition, positive performance persistence is observed among funds investing in large-cap stocks and stocks of high past performance. Finally, outperformance and positive performance persistence of equity funds are still present in various ranking and postranking horizons. These empirical findings are in sharp contrast with results from earlier studies on markets in developed countries, such as the United States.     

股票的权益比、账面市值比及其公司规模与股票投资风险——以上海证券市场的10只上市公司股票投资风险为例

最近20年来一些学者对CAPM理论模型检验的结果大都表明,股票的投资风险(或其收益)并非像该模型描述的那样由β系数唯一决定,还存在其他因素在股票投资风险中起影响作用。国内学者借助于横截面法的回归模型研究指出,股票的权益比率(D/E)、账面/市值价值比(BV/MV)与公司规模是决定股票投资风险除β系数外的三个主要经济变量。为了验证他们理论的正确性与精确性,该文率先运用模糊数学的聚类分析法,对上证市场随机选取10只样本股票的D/E、BV/MV、公司规模与股票投资风险相关性进行实证分析,并与用回归分析方法得到的β指数与风险关系进行比较研究。经研究进一步证实,股票投资风险并非唯一由β系数决定,股票的D/E、BV/MV及其公司规模应当成为β系数以外影响股票投资风险不可忽视的重要因素。本文研究的意义在于建议股票投资者,衡量股票投资风险不仅要考察股票的β系数,还应进一步考察股票的D/E、BV/MV和公司规模等。     

An Analysis of Contrarian Investment Strategies in the UK

The performance of contrarian, or value strategies – those that invest in stocks that have low market value relative to a measure of their fundamentals – continues to attract attention from researchers and practitioners alike. While there is much extant evidence on the profitability of value strategies, however, most of this evidence pertains to the US. In this paper, we provide a detailed characterisation of value strategies using data on UK stocks for the period 1975 to 1998. We first undertake simple one-way and two-way classifications of stocks in which value is defined using both past performance and expected future performance. Using sales growth as a proxy for past performance and book-to-market, earnings yield and cash flow yield as measures of expected future performance, we find that that stocks that have both poor past performance and low expected future performance have significantly higher returns than those that have either good past performance or good expected future performance. Allowing for size effects in returns reduces the value premium but it nevertheless remains significant. We go on to explore whether the profitability of value strategies in the UK can be explained using the three factor model of Fama and French (1996). Broadly consistent with the results for the US, we find that using the one-way classification the excess returns to almost all value strategies can be explained by their loading on the market, book-to-market and size factors. However, in contrast with the US, using the two-way classification there are excess returns to value strategies based on book-to-market and sales growth, even after controlling for their loading on the market, book-to-market and size factors.     

商业银行参与PE业务的现状、问题及策略建议

在后危机时代,我国商业银行应积极参与PE业务,实现支持经济可持续增长与拓宽盈利渠道的双赢。现阶段我国商业银行参与PE业务的基本路径可概括为:迂回直投模式、合作模式与间接模式。从外部环境看,我国PE市场发展的税收和政策安排还不够完善,资本市场为PE提供的退出通道较为狭窄,交易透明度有待进一步提高等;而商业银行内部也存在着风险管理、人才筛选等方面的难题。我国商业银行渐进拓展PE业务应制定严格的风险控制导向的业务监督体系和运营操作流程;积极引进和培养专业人才;选择合适的参与方式、投资阶段、投资产业与投资地域等。
