The key aim of this serial papers is to study various stochastic models in finance with emphasis on the Monte Carlo simulations with R for these models.In this paper,we studied the Black-Scholes model,which was originally established by Black and Scholes and later developed by Merton.Our emphasis is still on the Monte Carlo simulations with R.Compared with the Black-Scholes formulas on the option values,we show once again the power of the Monte Carlo simulations.
