有 Markovian 到达和税支付的一个风险模型被考虑。当保险公司处于一种有利状况时,保险公司可以作为税支付付高级收入的某个比例。首先,时间的 Laplace 变换被讨论在毁灭前穿过某个水平。第二,没有税和第一经过时间的 Laplace 变换,为概括 Gerber-Shiu 功能的明确的公式在毁灭前以原来的 Gerber-Shiu 功能被建立。最后,微分方程由期望的积累的打折的税支付满足了直到毁灭被导出。为打折的税支付的明确的表情也被给。
A risk model with Markovian arrivals and tax payments is considered.When the insurer is in a profitable situation,the insurer may pay a certain proportion of the premium income as tax payments.First,the Laplace transform of the time to cross a certain level before ruin is discussed.Second,explicit formulas for a generalized Gerber-Shiu function are established in terms of the'original'Gerber-Shiu function without tax and the Laplace transform of the first passage time before ruin.Finally,the differential equations satisfied by the expected accumulated discounted tax payments until ruin are derived.An explicit expression for the discounted tax payments is also given.
