This paper is divided into two parts. First, we consider a modified version of the Black-Scholes option pricing model which takes transaction costs into consideration by combining knowledge of Brownian Motion and Ito Process with mathematical tools of calculus, probability theory and mathematical statistics. Further, the solution of the model illustrates that introducing transaction costs greatly alters the levels of volatility. In part two, this paper illustrates plots of the result of the modified model by using python and empirical analysis by using R. It is found that the frequency of transaction volume adjustments and the ratio of transaction costs to call and put option results exhibit opposite behaviours in plots of result. What’s more, in empirical analysis, the modified model also gives a better simulation compared to original B-S model. Finally, further issues related to transaction costs are discussed.
