谱单边Lévy过程的破产时间约束最优分红问题

A time of ruin constrained optimal dividend problem for spectrally one-sided Lévy processes

Camilo Hernandez, Mauricio Junca, Harold Moreno-Franco

摘要:

通过对破产时间的限制,我们在经典的最优分红问题中引入了长寿特征。我们推广了\cite{HJ15}中的结果,现在在单侧Lévy风险模型的背景下。我们认为,在两种情况下,有和没有固定的交易成本,如税收的de Finetti的问题。我们还研究了所谓的对偶模型的约束模拟。为了描述上述模型的解决方案,我们引入了对偶问题,并表明互补松弛条件得到满足,因此没有对偶间隙。因此,最优值函数可以作为Lagrange乘子索引的辅助值函数的逐点下确界来获得。最后,我们用一系列的数值例子来说明我们的研究结果。

英文摘要:

We introduce a longevity feature to the classical optimal dividend problem by adding a constraint on the time of ruin of the firm. We extend the results in \cite{HJ15}, now in context of one-sided Lévy risk models. We consider de Finetti's problem in both scenarios with and without fix transaction costs, e.g. taxes. We also study the constrained analog to the so called Dual model. To characterize the solution to the aforementioned models we introduce the dual problem and show that the complementary slackness conditions are satisfied and therefore there is no duality gap. As a consequence the optimal value function can be obtained as the pointwise infimum of auxiliary value functions indexed by Lagrange multipliers. Finally, we illustrate our findings with a series of numerical examples.
