Vasicek model parameter estimation

Many scholars use the generalized moment estimate method (GMM) and maximun likelihood estimate (MLE) to estimate the parameters of Vasicek. However, the parameter estimation of the GMM is not stable. Selecting different moment condition estimates will lead to different Before conduct all the estimation and simulations with the Vasicek model and the CIR model, related articles are reviewed and can be separated into two aspects. One is about the short-term interest rate models, and the other is about the estimation method and applications of the method from the previous studies. 2.1 Short-term interest rate models Vasicek, Cox Ingersoll Ross (CIR), Dothan, for instance, are among the frequently-used short-rate models. The strength of Vasicek model is analytical bond prices and analytical option prices can be obtained and easily calculatied, however, negative short rates are also possible with positive probability. Starting point of this paper is the modelling of a stock index.

literatures have been devoted to the parameter estimation for the models with t-stable noises. When the coefﬁcient is constant, drift parameter estimation has been investigated ( [17]–[19]). Vasicek model, which was introduced by Oldrich Alfons Vasicek in 1977( [23]), is a mathematical model describing the evolution of interest rates.

After introducing the Black model, we used it to price caps and caplets. We also examined the R code for the Black-Scholes model. Then, we turned our attention to interest rate models such as the Vasicek and CIR models. We discussed the theory of parameter estimation as The Vasicek model.
