摘要
在文献[8]的基础上探讨标的资产价格由分数布朗运动驱动且具有连续红利分配的永久美式期权的定价问题,对永久美式看涨期权和看跌期权的定价及其提前实施期权时临界标的资产的价格给出了相应的解析解,分析了红利率的变化对永久美式期权提前实施的影响.
Based on literature [ 8 ] , it is discussed that pricing for perpetual American options with underlying asset driven by fractional Brownian motion and accompanied continuous dividends. Explicit solutions are given for the prices of the perpetual American call and the perpetual American put. The corresponding critical asset prices for early exercise are also given explicitly. Furthermore, the influence of change of dividends on early exercise of perpetual American options is analyzed.
