摘要翻译：
考虑一个保险公司的最优股利问题，其不受控制的盈余过程演化为一个谱负利税过程。我们假设股利是按照股利率为常数的可容许策略支付给股东的。目标是寻找一个股利政策，使股利的预期折现值最大化，直到公司破产为止。Kyprianou,Loeffen和Perez[28]已经证明，在Levy测度具有完全单调密度的条件下，折射策略（也称为阈值策略）形成最优策略。在本文中，我们提出了一个替代的方法来解决这个最优问题。

英文摘要：
  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. Kyprianou, Loeffen and Perez [28] have shown that a refraction strategy (also called threshold strategy) forms an optimal strategy under the condition that the Levy measure has a completely monotone density. In this paper, we propose an alternative approach to this optimal problem.
