Based on the principle of control variables method,this paper adopts CV-CRR method of the American option on the basis of Black-Scholes option pricing formula,and it also makes an empirical analysis to prove that the control variables method can be used to greatly improve the operating speed and valuation precision of the standard binary tree method,thus improve the effciency of valuation.
本文基于控制变量法原理,在Black-Scholes期权定价公式的基础上,采用CV-CRR方法为美式看跌期权定价。
