摘要翻译:
我们重新讨论了Avanzi等人的对偶模型中的股利支付问题。([2],[1]和[3])。利用谱正L{e}vy过程的涨落理论,我们对所有这类L{e}vy过程给出了一个简短的说明,其中我们证明了势垒策略的最优性。此外,我们利用尺度函数的泛函逆刻画了最优势垒。我们还考虑了[3]中的资本注入问题,证明了它的价值函数与以破产时间为时域的价值函数具有非常相似的形式。

英文摘要:
We revisit the dividend payment problem in the dual model of Avanzi et al. ([2], [1], and [3]). Using the fluctuation theory of spectrally positive L\'{e}vy processes, we give a short exposition in which we show the optimality of barrier strategies for all such L\'{e}vy processes. Moreover, we characterize the optimal barrier using the functional inverse of a scale function. We also consider the capital injection problem of [3] and show that its value function has a very similar form to the one in which the horizon is the time of ruin.
