在我国上市公司股权激励制度背景下,为进一步检验股权激励对上市公司股利分配行为的影响效应.从管理者寻租的视角出发,以2010-2017年上证A股非金融类上市公司为研究样本,实证分析了股权激励对上市公司现金股利政策的影响.在此基础上,创新性地将控股股东股权性质以及公司规模作为调节变量构建了多元线性回归模型并求解.研究结果表明,股权激励对上市公司现金股利政策具有正向影响,且对非国有控股上市公司影响更为显著.丰富了高管股权激励及公司股利政策的相关研究.     

控股股东股权质押与CEO非正常离职行为北大核心CSCD

CEO离职是影响公司发展的重大事件,现有文献主要探讨了高管与公司特征对高管离职的影响,研究股东行为对于CEO离职影响的文献还较为匮乏.文章以2007-2017年A股上市公司为样本,实证检验控股股东股权质押对CEO非正常离职的影响.结果发现,控股股东股权质押会增加CEO非正常离职的概率,在使用工具变量回归及PSM方法解决可能的内生性问题之后结论依然成立.进一步的研究发现,前述效应对于国有企业和由控股股东委派的CEO而言并不明显;此外,在控股股东股权质押之后,竞争能力更强的CEO的离职倾向更明显,而更好的公司治理水平能抑制控股股东股权质押对CEO离职的影响.文章在一股独大的背景下,探讨公司的CEO这一极其重要的利益相关者会如何对控股股东的股权质押行为做出反应,既拓展了股权质押相关研究文献,也有利于学术界从动态的视角理解影响CEO离职背后的股东行为因素.

控股股东委派董事与分类转移盈余管理——高管激励中介效应和机构持股调节效应

以高管激励为中介变量,机构投资者持股比例为调节变量,以2007年-2018年期间沪深两市A股上市公司为研究对象,考察了控股股东委派董事对分类转移盈余管理的影响。研究发现:控股股东委派董事对分类转移盈余管理具有显著的抑制影响,说明控股股东委派董事可以有效履行其监督职能;高管薪酬激励和高管股权激励在控股股东委派董事与分类转移盈余管理程度之间发挥了部分中介作用;机构投资者股权越大,分类转移盈余程度越低,但削弱了控股股东委派董事对分类转移盈余管理的正向监督效应。本文有助于完善控股股东委派董事监督分类转移盈余行为的影响路径,对上市公司调整高管激励结构和完善投资者治理具有重要的启示意义。     

限售股减持背景下控股股东自利行为研究——基于跨期投资的视角

以减持限售股份为前提条件,建立起两期间的控股股东跨期投资并进行利益侵占的理论模型。将现金流权比例、限售股减持比例等作为影响变量,分析其对控制权私利产生怎样的作用。通过分析得出产生的控制权私利分别与上述相关比例之间是呈负相关、正相关以及只与即期有关而与远期侵占无关的结论。同时,两期侵占模型中,控股股东的即期最佳水平与单期模型相比,有一定程度的降低。因为控股股东的减持以及侵占行为是长时间的,并且也是连续的,该行为是以获得最大收益为目的的。本文在理论分析的角度为我国资本市场的大股东持股结构改善以及投资决策选择给予支撑。

Optimality of the threshold dividend strategy for the compound Poisson model

In this paper, we consider the optimal dividend problem for the compound Poisson risk model. We assume that dividends are paid to the shareholders according to an admissible strategy with dividend rate bounded by a constant. Our objective is to find a dividend policy so as to maximize the expected discounted value of dividends until ruin. We give sufficient conditions under which the optimal strategy is of threshold type.     

Optimal dividends in the Brownian motion risk model with interest

In this paper, we consider a Brownian motion risk model, and in addition, the surplus earns investment income at a constant force of interest. The objective is to find a dividend policy so as to maximize the expected discounted value of dividend payments. It is well known that optimality is achieved by using a barrier strategy for unrestricted dividend rate. However, ultimate ruin of the company is certain if a barrier strategy is applied. In many circumstances this is not desirable. This consideration leads us to impose a restriction on the dividend stream. We assume that dividends are paid to the shareholders according to admissible strategies whose dividend rate is bounded by a constant. Under this additional constraint, we show that the optimal dividend strategy is formed by a threshold strategy.     

Classical and singular stochastic control for the optimal dividend policy when there is regime switching

Motivated by economic and empirical arguments, we consider a company whose cash surplus is affected by macroeconomic conditions. Specifically, we model the cash surplus as a Brownian motion with drift and volatility modulated by an observable continuous-time Markov chain that represents the regime of the economy. The objective of the management is to select the dividend policy that maximizes the expected total discounted dividend payments to be received by the shareholders. We study two different cases: bounded dividend rates and unbounded dividend rates. These cases generate, respectively, problems of classical stochastic control with regime switching and singular stochastic control with regime switching. We solve these problems, and obtain the first analytical solutions for the optimal dividend policy in the presence of business cycles. We prove that the optimal dividend policy depends strongly on macroeconomic conditions.     

Alternative approach to the optimality of the threshold strategy for spectrally negative Lévy processes

Consider the optimal dividend problem for an insurance company whose uncontrolled surplus precess evolves as a spectrally negative Levy process. We assume that dividends are paid to the shareholders according to admissible strategies whose dividend rate is bounded by a constant. The objective is to find a dividend policy so as to maximize the expected discounted value of dividends which are paid to the shareholders until the company is ruined. In this paper, we show that a threshold strategy （also called refraction strategy） forms an optimal strategy under the condition that the Levy measure has a completely monotone density.     

A Markov decision problem in a risk model with interest rate and Markovian environment

We consider the compound binomial model in a Markovian environment presented by Cossette et al.(2004). We modify the model via assuming that the company receives interest on the surplus and a positive real-valued premium per unit time, and introducing a control strategy of periodic dividend payments. A Markov decision problem arises and the control objective is to maximize the cumulative expected discounted dividends paid to the shareholders until ruin minus a discounted penalty for ruin. We show that under the absence of a ceiling of dividend rates the optimal strategy is a conditional band strategy given the current state of the environment process. Under the presence of a ceiling for dividend rates, the character of the optimal control strategy is given. In addition, we offer an algorithm for the optimal strategy and the optimal value function.Numerical results are provided to illustrate the algorithm and the impact of the penalty.     

Dependence of the Optimal Risk Control Decisions on the Terminal Value for a Financial Corporation

The paper deals with the model of a firm which has a possibility to choose among a variety of production/business policies with different risk and profit potential. The objective is to find the policy which maximizes the expected total discounted dividend pay-out until the time of bankruptcy. The bankruptcy is defined as the time when the liquid assets of the company vanish. A typical example of such a corporation would be an insurance company whose different business activities correspond to choosing different levels of reinsurance.The main novelty of this model is in introduction of terminal value of the company at the time of the bankruptcy. This could be the value of non liquid assets (such as real estate or the rights to conduct business or the trade name), which at the time of bankruptcy are subject to sale with proceeds distributed among shareholders. We model the dynamics of the corporate liquid assets as a diffusion process with controllable drift and diffusion coefficients. Diffusion coefficient corresponds to risk, while drift represents potential profit. In our model the potential profit proportional to the risk. The dividend distribution is modeled by an increasing functional, which is also controllable. We show how to obtain solution for this problem starting with the solution to the problem with zero terminal value.     

On optimality of the barrier strategy for the classical risk model with interest

In this paper, we consider the optimal dividend problem for a classical risk model with a constant force of interest. For such a risk model, a sufficient condition under which a barrier strategy is the optimal strategy is presented for general claim distributions. When claim sizes are exponentially distributed, it is shown that the optimal dividend policy is a barrier strategy and the maximal dividend-value function is a concave function. Finally, some known results relating to the distribution of aggregate dividends before ruin are extended.     

Optimization of a dividend strategy of an insurance company continuing its work after the ruin

A model of the work of an insurance company is considered. It is supposed that the company applies a barrier dividend strategy and shareholders cover the deficit at the time of ruin so that the company can continue its functioning after the ruin. The existence of strategies maximizing either the dividend amount, or the profit of shareholders is proved both for discrete and continuous time.     

Dividend payments in the classical risk model under absolute ruin with debit interest

This paper attempts to study the dividend payments in a compound Poisson surplus process with debit interest. Dividends are paid to the shareholders according to a barrier strategy. An alternative assumption is that business can go on after ruin, as long as it is profitable. When the surplus is negative, a debit interest is applied. At first, we obtain the integro‐differential equations satisfied by the moment‐generating function and moments of the discounted dividend payments and we also prove the continuous property of them at zero. Then, applying these results, we get the explicit expressions of the moment‐generating function and moments of the discounted dividend payments for exponential claims. Furthermore, we discuss the optimal dividend barrier when the claim sizes have a common exponential distribution. Finally, we give the numerical examples for exponential claims and Erlang (2) claims.
