为了刻画金融资产价格呈现的长期记忆性特征,采用赋权分数布朗运动来描述风险资产价格的动态变化过程.考虑到金融市场的不确定性,即具有随机性和模糊性的特征,采用随机分析理论和模糊集理论构建了不确定环境下赋权分数布朗运动驱动的欧式期权定价模型,并推导出了欧式看涨期权和欧式看跌期权的定价公式.
The European Option Pricing Model Based on the Weighted Fractional Brownian Motion in a Fuzzy Environment
In order to describe the long-term memory characteristics presented by the prices of financial assets,the weighted fractional Brownian motion is adopted to depict the dynamic change process of the prices of risky assets.Considering the uncertainty of the financial market,which features both randomness and fuzziness,the stochastic analysis theory and the fuzzy set theory are used to construct the European option pricing model driven by the weighted fractional Brownian motion in an uncertain environment,and the pricing formulas for European call options and European put options are derived.
