具有交易费用和注资约束的最优纾困分红问题

Optimal bail-out dividends problem with transaction cost and capital injection constraint

Mauricio Junca, Harold Moreno-Franco, José Luis Pérez

摘要:

本文考虑了Lévy风险模型下固定交易费用下的最优分红问题。此外,我们考虑的版本与约束的期望净现值注入资本。为了刻画上述模型的解的特征,我们首先解决了在交易成本和资本注入下的纾困最优股息问题,并证明了反射(c1; c2)政策的最优性。接下来,我们介绍了对偶拉格朗日问题,并证明了互补松弛条件得到满足,表征了最优拉格朗日乘子。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 consider the bail-out optimal dividend problem under fixed transaction costs for a Lévy risk model. Furthermore, we consider the version with a constraint expected net present value of injected capital. To characterize the solution to the aforementioned models, we first solve the bail-out optimal dividend problem under transaction costs and capital injection and show the optimality of reflected (c1; c2)- policies. Next, we introduce the dual Lagrangian problem and show that the complementary slackness conditions are satisfied, characterizing the optimal Lagrange multiplier. Finally, we illustrate our findings with a series of numerical examples.
