我国企业高管股权激励与研发投资——基于内生性视角的研究

本文以2002—2009年我国上市公司为研究对象,探讨了股权分置改革前后我国企业管理层股权激励对研发投资的影响,并在此基础上检验了管理层股权激励的内生性。研究发现,高管股权激励存在内生性,在控制了内生性之后,股改前股权激励与研发投资之间存在倒U形曲线关系;股改后股权激励对研发投资具有显著的正向影响。本文结果表明应该将研发投资作为股权激励方案的激励条件之一;此外,合理的安排股东与管理层之间的股权配置比例是保证企业有效进行研发投资、提升企业自主创新能力的必要手段。本文的结论深化了我们对股权激励内生性的理解,并为我国企业更好地实施管理层股权激励和企业自主创新战略提供了理论支持和实证证据。     

产权性质、股权激励与企业技术创新——基于我国中小板上市公司的经验分析

本文以连续3年披露研发支出的73家中小板上市公司为研究样本,分析产权性质、股权激励对企业技术创新的影响,在充分控制其他影响企业技术创新的因素后,研究发现:第一,经营者持股和以股票期权为主的股权激励机制显著地促进了企业技术创新;第二,民营产权弱化了经营者持股对企业技术创新的促进作用;第三,以股票期权为主的股权激励机制对企业技术创新的影响并未显著受到产权性质的约束。     

股权激励、反收购条款与企业创新

股权激励和反收购措施是公司内外部治理机制的重要方式.文章以2006—2017年沪深两市上市公司为研究样本,将股权激励、反收购条款和企业创新纳入统一分析框架中,考察两种公司治理机制对企业创新的综合影响.研究发现:股权激励显著提升企业创新产出水平,但反收购条款负向调节股权激励对企业创新的促进作用,控制内生性后结论依然成立.进一步分情景分样本进行分析发现,股权激励的创新效果相对稳定,但反收购条款的负向调节作用明显受外界环境和条件的影响,主要体现在市场竞争程度低、股权分散程度低及高管风险偏好程度低的企业中.本文的研究结论对理解股权激励的实施效果及反收购条款的公司治理作用具有一定的参考意义.     

高新技术企业股权激励与业绩的相关性分析

股权激励是在所有权与经营相分离的情况下,企业为了激励经营者努力工作而采取的一种内部分配制度.我国高新技术上市公司已开始实施股权激励.文章以高新技术上市公司2010年年报为依据,通过对是否实施股权激励公司业绩以及持股比例与公司业绩的实证研究,发现实施股权激励对公司业绩是否有显著影响     

湖南省上市公司股权激励状况调查与分析

本文以湖南省上市公司为样本,考查了股权激励在湖南省上市公司实施的情况。经过实地调查与分析,发现湖南省上市公司实施股权激励的公司比例远低于国外,但股权激励的强度较大。研究还发现股权激励对湖南省上市公司短期业绩的影响总体来说并不明显,非国有控股公司更倾向于推出股权激励方案。     

基于高科技行业的管理层股权激励与企业价值关系的实证研究

论文运用面板数据的多元统计分析方法对沪深两市高科技行业上市公司的管理层股权激励和企业价值的关系进行实证研究，结果发现：企业价值与管理层股权激励比例、经营活动现金流量／总资产、息税前利润／总资产正相关，与企业规模、资产负债率、国有股比例负相关。并根据研究结果提出了相关建议。     

家族企业股权制衡度与企业价值的门槛效应分析

本文以2010~2014年全部A股上市的家族企业平衡面板数据为样本,通过多元回归分析和固定效应面板门槛回归模型研究了基于不同企业特征下,股权制衡度与企业价值之间的关系。研究发现:企业规模、家族控制程度及两权分离度对股权制衡具有门槛效应,股权制衡度对企业价值的影响效果会随着门槛变量的改变而改变,家族企业股权制衡度与企业价值之间的关系并非严格意义上的"倒U型"关系,而是非平滑对称的曲线,不同的门槛变量,两者之间呈现不同的影响方向和影响程度。本文为股权制衡影响家族企业的路径和作用机制提供经验证据,而且门槛回归结果更能反映真实情况,能够更好地解释股权制衡度与企业价值之间的关系。     

大股东控制权对股权激励效果的影响

本文分析了大股东控制权实现过程中对管理层股权激励的监督或冲突作用以及这种影响在不同股权性质和不同成长性公司中的不同表现。研究发现:大股东控制对管理层的作用显著影响股权激励效果;国有控股上市公司大股东对管理层的监督作用明显,随着第一大股东持股比例的增大,管理层股权激励效果增强;民营控股上市公司大股东控制权与管理层股权激励之间存在冲突,第一大股东持股比例越高,股权激励效果越差;高新技术企业大股东控制权与管理层股权激励之间存在冲突;非高新技术企业中第一大股东与管理层之间存在不明显的监督作用。本文的研究结论从股权激励的公司治理环境角度解答了我国股权激励效果不佳的困惑,为不同类型的上市公司启用管理层股权激励方案时考虑适宜的公司治理环境特别是大股东控制程度提供了经验证据。     

股权激励与企业业绩相关性分析——基于上交所A股上市公司

本文以上海证券交易所A股上市公司为研究对象,对高管股权激励与企业经营业绩之间的关系进行实证分析。分析结果表明股权激励与企业经营业绩呈正相关关系,同时,股权激励水平很大程度上也受到企业规模大小的影响。     

非高管股权激励与企业创新:公平理论视角

股权激励管理办法允许上市公司通过股权激励计划对部分非高管员工进行股权激励,但设定激励对象等方面的有关规定对企业的影响却鲜有研究关注。本文从公平理论视角分析我国非高管员工股权激励对上市公司创新的影响,并依据中国上市公司股权激励计划与专利数据实证检验了非高管员工股权激励有效性假说与不公平假说。研究发现,总体上我国股权激励计划能够显著促进企业创新,但非激励员工因薪酬不公平而产生的消极行为在一定程度上削弱了股权激励计划的激励效果。具体而言,在国有控股上市公司以及激励与非激励员工收入差距小的上市公司中,非高管股权激励弱化企业创新的影响明显小于其他公司;而在非高管员工覆盖比例较高的公司中,非高管股权激励计划弱化企业创新的影响不存在。因此适当提高员工股权激励覆盖的范围可以减少激励员工与非激励员工之间因激励错配导致的薪酬不公平问题,有助于提升我国上市公司股权激励计划的创新激励效果。     

East and west and north and south : A preliminary model

The Brandt report and other proposals for a new North-South world order continue to be the focus of lively debate, yet it is often argued that little concrete has emerged from their recommendations. A major reason for this, the author argues, is that the East-West conflict component is not sufficiently taken into consideration-East-West tensions are a severe constraint on and a determining factor of North-South relations. Using influence diagrams, the author develops a flexible framework for discussion and assessment of N/S-E/W relations.

Stock and Bond Liquidity and its Effect on Prices and Financial Policies

An asset is liquid if it can be traded at the prevailing market price quickly and at low cost. We show that in addition to risk, liquidity affects asset prices and returns. Theories of asset pricing suggest that the expected return of an asset is increasing in its risk, because risk-averse investors require compensation for bearing more risk. Because investors are also averse to the costs of illiquidity and want to be compensated for bearing them, asset returns are increasing in illiquidity. Thus, asset prices should depend on two asset characteristics: risk and liquidity. This paper surveys research on the effects of liquidity on asset prices and returns, showing that liquidity is an important factor in capital asset pricing.     

垄断与通货膨胀:理论与证据

本文从微观层面构建多维状态非线性系统理论模型,应用非线性模型预测控制方法研究了垄断与通货膨胀之间的关系。理论分析表明,垄断与通胀存在明显的正向关系。本文进一步应用变系数半参数估计方法为上述理论预期提供了经验支持,并发现我国在生产效率较低的行业中,垄断会导致显著的通胀效应,但这种效应在生产效率较高的行业中则明显减弱。上述结论对我国当前“下限保增长、上限防通胀”的宏观调控目标具有重要的启示意义。     

教育与资本怎样的前景怎样的现实

来自政府的声音: "动员各种社会资源,发展教育" 此次论坛上财政部长助理张少春的发言是最受关注的发言之一.他的演讲传达出的信息有这样几方面:第一,谈到现实,他认为全社会对教育的巨大需求与我国公共投入不足已成为我国教育事业发展的突出矛盾.近年来,以公共部门投入为主,多渠道筹措教育经费的教育投入机制成为解决这一问题的重要途径,也使得公共部门与私营部门在教育领域的合作日益密切.第二,谈到前景,他认为,1.中国经济持续、快速的增长对高技能人才产生巨大的需求,这为私营部门的参与提供了广阔空间.2.随着公共财政职能的不断完善,财政资金将在各项教育事业中重新进行分配,进一步优化财政支出结构,提高资金的使用效率.在"十一五"期间,我国将把公共支出的重点转移到农村.我们将逐步把全体农村适龄儿童的义务教育全部纳入公共财政体制.     

Fast and slow cancellations and trader behavior

We investigate how short-lived liquidity supply due to order cancellations affects the order-placement behavior of slow traders. When order cancellations increase, slow traders submit fewer and less aggressive orders. Both short- and long-lived liquidity supply have positive effects on the market overall, reducing spreads and increasing depth. We conclude that it is not necessary to require limit orders to have a minimum lifespan. We develop econometric and machine-learning frameworks that allow traders to predict whether a quote is likely to have a short or long life, increasing the ability of slow traders to respond strategically to changing order flow.     

Amplification and asymmetry in crashes and frenzies

We often observe disproportionate reactions to tangible information in large stock price movements. Moreover these movements feature an asymmetry: the number of crashes is more than that of frenzies in the S&P 500 index. This paper offers an explanation for these two characteristics of large movements in which hedging (portfolio insurance) causes amplified price reactions to news and liquidity shocks as well as an asymmetry biased towards crashes. Risk aversion of traders is shown to be essential for the asymmetry of price movements. Also, we show that differential information can enhance both amplification and asymmetry delivered by hedging. This paper is based on part of my Ph.D. thesis submitted to the University of Minnesota. I am grateful to Andy McLennan and Jan Werner for their valuable advice and unwavering support. Also, I would like thank Mehmet Barlo, Michele Boldrin, Partha Chatterjee, Mehmet Ozhabes, Dimitrios Tsomocos and seminar participants at the University of Minnesota, the MEA and the MFA Meetings in St Louis for helpful comments. Comments on a previous draft by an anonymous referee greatly improved the presentation of this paper. Financial support from William W. Stout Fellowship is gratefully acknowledged.     

LIBOR and swap market models and measures

A self-contained theory is presented for pricing and hedging LIBOR and swap derivatives by arbitrage. Appropriate payoff homogeneity and measurability conditions are identified which guarantee that a given payoff can be attained by a self-financing trading strategy. LIBOR and swap derivatives satisfy this condition, implying they can be priced and hedged with a finite number of zero-coupon bonds, even when there is no instantaneous saving bond. Notion of locally arbitrage-free price system is introduced and equivalent criteria established. Stochastic differential equations are derived for term structures of forward libor and swap rates, and shown to have a unique positive solution when the percentage volatility function is bounded, implying existence of an arbitrage-free model with such volatility specification. The construction is explicit for the lognormal LIBOR and swap “market models”, the former following Musiela and Rutkowski (1995). Primary examples of LIBOR and swap derivatives are discussed and appropriate practical models suggested for each.     

Debt and Taxes and Uncertainty

With a graduated personal tax schedule, Miller showed that there could be an equilibrium debt supply for the corporate sector as a whole. In the presence of uncertainty there is also a unique debt/equity ratio for each individual firm, and this ratio is related to the firm's operational risk characteristics. However, if firms merge and spin off in response to tax incentives, the identity of firms is ambiguous and only the corporate sector is a meaningful construct. These arguments are developed in both discrete and continuous models that employ extensions of the arbitrage-free pricing theory.
