摘要
在Vasicek模型下,利用Δ-对冲和资产价格服从分数布朗运动(FBM)的逼近过程的方法,获得了欧式期权定价模型,并得到了其解析式,改进了经典的Black-Scholes公式。
European options pricing model is obtained under Vasicek model by using the methods of Δ--hedging and approximation process of assets price which is driven by fractional Brownian motion(FBM), and the close formula is also given. As a result, the classical Black-Scholes formula is improved.
