Abstract

我们将专注于在离散时间内以交易成本进行复制。 为了做到这一点，，我们将以交易成本对选项复制进行系统审查。 期权复制模型基于Cox-Ross-Rubinstein二项期权定价模型。 本文将对Boyle和Vorst的长期和短期期权方案进行离散时间法的研究，并对数值改变各种参数的影响进行调查研究。We will be focusing on the option replication in discrete time with transaction costs. To do this we will review systematically on the option replication with transaction costs. The model on option replication is based on the Cox-Ross-Rubinstein binomial option pricing model. The paper willimplement the discrete-time method of Boyle and Vorst for long and short call optionprices, and investigate numerically the effect of changing thevarious parameters.

1. Introduction介绍

爱因斯坦和维纳在1905年提出的函数功能的重要性质。使用布朗运动，Bachelier（1900）具体描述了股票价格的变化，并提供了欧式看涨期权的公式。 Black＆Scholes（1973）提出了着名的Black-Scholes模型。此外，Merton（1973）在许多方面系统地研制了Black-Scholes模型和定价公式。 The history of option price should back to the French mathematician Louis Bachelier in 1900. He has realized some important properties of Wiener function proposed by Einstein and Wiener in 1905. Using the Brownian motion, Bachelier (1900)has specifically described the change of stock price and provided the formula of European call option. Black &Scholes (1973) proposed the famous Black-Scholes model. Moreorevision times increase, the option price will slightly increase. With the fixed number of revision time, when the riskless continuous interest rate increases, the option price will significantly increase. By comparing the different standard deviation of the European long call price, with fixed transaction cost rate on stocks, when the number of revision time increases, the option price will slightly decrease. Moreover, there is positive relationship between the volatility of the risky asset (standard deviation) and option price. 
By comparing the European short call price, the transaction cost rate on stocks k can negatively affect the option price. Moreover, there is negative relationship between option price and the riskless continuous interest rates. There is significant difference between the option price without transaction costs and the option price with transaction costs. Both the Black Scholes approximation and Leland’s approximation can get accurate value of option price. On the other hand, when there are transaction costs, there is no significant difference between the Black Scholes approximation and the Leland’s approximation.
