摘要
研究了常利率投资和线性阈值分红策略下的绝对破产模型,利用全概率公式、Taylor展式求解绝对破产前累计分红现值的矩母函数和n阶矩函数的更新方程,得到Gerber-Shiu期望折现罚金函数的偏微分方程表达式.
The paper mainly analyzes the absolute ruin risk model with constant interest investment and a linear threshold dividend strategy.By formula of full probability and Taylor expansion,renewal equations of moment-generating function and nth moment with present value of total dividends until absolution ruin are obtained.Further,partial integrodifferential equations of Gerber-Shiu function are given.
