利用鞅方法给出了在无风险资产有依赖时间参数的利率r(t)和风险资产支付红利,并且有依赖时间参数的期望收益率u(t)、波动率σ(t)及红利率ρ(t)的情况下,几何型具有浮动敲定价格的亚式期权的定价模型.
Under the circumstances of time-dependent interest rate r(t) of riskless asset, dividend payment of risk asset,time-dependent expected return μ(t) ,volatility σ(t) and dividend yield ρ(t), the authors use martingale to establish a pricing model of geometric Asian options with floating strike price.
