我国上市公司超能力派现的实证研究——以深市上市公司2004年为例

以2004年深圳证券交易所的213家派现公司为样本,利用Logistic模型研究上市公司的超能力派现问题,文章将超能力派现定义为每股派发现金额大于每股经营现金净流量.研究结果发现,超能力派现与上市公司的上市年限、国有股比例、流通股比例显著正相关;而与资产规模、净资产收益率、第一大股东的关系不具有统计意义上的显著性.     

再融资公司的现金分红和现金流操控研究

证监会2006年和2008年相继发布了强制拟再融资上市公司分派现金股利的文件,旨在提高股东回报。以2006年和2007年A股再融资上市公司为样本,对这些政策颁布前后上市公司分红和现金流的变化情况进行研究发现,在证监会强制要求下,上市公司的分红水平有所提高,但股利分派也成为了大股东转移公司利益的手段。而且,公司的现金流在再融资前后波动较大,存在被操控的迹象。     

Equilibrium Pricing in the Presence of Cumulative Dividends Following a Diffusion

The paper presents some security market pricing results in the setting of a security market equilibrium in continuous time. The theme of the paper is financial valuation theory when the primitive assets pay out real dividends represented by processes of unbounded variation. In continuous time, when the models are also continuous, this is the most general representation of real dividends, and it can be of practical interest to analyze such models.
Taking as the starting point an extension to continuous time of the Lucas consumption-based model, we derive the equilibrium short-term interest rate, present a new derivation of the consumption-based capital asset pricing model, demonstrate how equilibrium forward and futures prices can be derived, including several examples, and finally we derive the equilibrium price of a European call option in a situation where the underlying asset pays dividends according to an Itô process of unbounded variation. In the latter case we demonstrate how this pricing formula simplifies to known results in special cases, among them the famous Black–Scholes formula and the Merton formula for a special dividend rate process.     

基于公司价值的股利理论及其政策的教学设计研究

股利政策是一个谜,财务管理理论中很多股利理论对它进行了不同解释。为了使应用型本科学生更好地理解并应用股利理论和股利政策,在基于公司价值的股利理论教学设计中,按股利支付是否与公司价值相关将股利理论进行了分类介绍。虽然每个解释都不全面,但总体上形成了相对系统的理论体系。为了使学生更生动具体地理解股利政策,文章对用友软件公司2001年至2011年的现金股利支付进行了分析,要求应用型本科学生根据股利生命周期理论进行股利政策选择,以促进公司价值增值。     

本轮宏观经济波动的理性思考

本轮宏观经济波动同已往的不同,主要是因为国际收支失衡而引起的,所以需要有新的办法,关键是要深化改革。紧缩中出现的问题,是与企业自身的资本金过低而债务资金过高有密切关系的,不能将问题仅仅归于从紧的货币政策。股市在紧缩中的下滑,不简单是政策问题,而是上市公司长期不分红的结果,不分红必然使投资者把股价涨落作为重点,从而使中国股市成为投机性很强的市场,而不是以投资为基点的市场,因而不能简单救市,而是要深化改革。     

关于股票股利及其会计处理的探讨

股票股利是最常见的一种股利分配方式。发放股票股利对公司和股东都会有一定的影响。股票股利也要在帐面反映出来。     

Rational Speculative Bubbles: An Empirical Investigation of the London Stock Exchange

In recent years, a sharp divergence of London Stock Exchange equity prices from dividends has been noted. In this paper, we examine whether this divergence can be explained by reference to the existence of a speculative bubble. Three different empirical methodologies are used: variance bounds tests, bubble specification tests, and cointegration tests based on both ex post and ex ante data. We find that, stock prices diverged significantly from their fundamental values during the late 1990's, and that this divergence has all the characteristics of a bubble.     

OPTIMAL DIVIDEND POLICY WITH MEAN-REVERTING CASH RESERVOIR

Motivated by empirical evidence and economic arguments, we assume that the cash reservoir of a financial corporation follows a mean reverting process. The firm must decide the optimal dividend strategy, which consists of the optimal times and the optimal amounts to pay as dividends. We model this as a stochastic impulse control problem, and succeed in finding an analytical solution. We also find a formula for the expected time between dividend payments. A crucial and surprising economic result of our paper is that, as the dividend tax rate decreases, it is optimal for the shareholders to receive smaller but more frequent dividend payments. This results in a reduction of the probability of default of the firm.
