英文摘要:
We propose a model in which dividend payments occur at regular, deterministic intervals in an otherwise continuous model. This contrasts traditional models where either the payment of continuous dividends is controlled or the dynamics are given by discrete time processes. Moreover, between two dividend payments, the structure allows for other types of control; we consider the possibility of equity issuance at any point in time. The value is characterized as the fixed point of an optimal control problem with periodic initial and terminal conditions. We prove the regularity and uniqueness of the corresponding dynamic programming equation, and the convergence of an efficient numerical algorithm that we use to study the problem. The model enables us to find the loss caused by infrequent dividend payments. We show that under realistic parameter values this loss varies from around 1% to 24% depending on the state of the system, and that using the optimal policy from the continuous problem further increases the loss.

中文摘要:
我们提出了一个模型,在该模型中,股息支付在其他连续模型中以固定的、确定性的间隔发生。这与传统模型不同,传统模型要么控制连续股息的支付,要么通过离散时间过程给出动态。此外,在两次股息支付之间,结构允许其他类型的控制;我们考虑在任何时候发行股票的可能性。该值被描述为具有周期性初始和终端条件的最优控制问题的不动点。我们证明了相应的动态规划方程的正则性和唯一性,以及用于研究该问题的有效数值算法的收敛性。该模型使我们能够发现不经常支付股息所造成的损失。我们表明,在实际参数值下,根据系统的状态,这种损失在1%到24%之间变化,并且使用连续问题的最优策略进一步增加了损失。
