European Option Pricing Under Subfractional Vasicek Stochastic Interest Rate Model
摘要
Abstract
In this article,the price of the European option is discussed through loosening the conditions of classical B-S model when assume that the interest rate is random fluctuations.As a carrier of the interest rate firstly.The price for the zero coupon bonds is given,and the mcaning of the market price of the interest rate risk is obtained.Secondly,by using the theory of portfolio hedge to structure the risk-free asset,the European option satisfies a partial differential equation driven by the sub-fractionai Brownian motion under stochastic interest rate model.Finally,the pricing formula is obtained afber turned it to the classical heat conduction equation thraugh uariable substitution.关键词
