Perbandingan nilai opsi call tipe Eropa dengan perluasan model Vasicek dan model Cox-Ingersoll-Ross

Abstract

Derivative product is a financial instrument whose value depends on the value of the underlying asset. One of the derivative product is a European option, which has the form of either call or put option. To determine the value of a European call option some models could be used, such as Vasicek and the Cox-Ingersoll-Ross model (CIR). Vasicek model may result in a negative interest rate, so that CIR model can be considered as an alternative in order to obtain nonnegative interest rates. This article discusses the European call option with a zero coupon bond as an underlying asset. The discussion includes the analysis and application of Vasicek and CIR models. The simulation results show that European call option price given by the extended Vasicek model and CIR model are similar.
