Demand Deposits: Valuation and Interest Rate Risk

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.

The fractional Vasicek model with long-range dependence is assumed to be driven by a fractional Brownian motion with the Hurst parameter greater than or equal to one half. econometrics Article Maximum Likelihood Estimation for the Fractional Vasicek Model Katsuto Tanaka 1,†, Weilin Xiao 2,† and Jun Yu 3,*,† 1 Faculty of Economics, Gakushuin University, Tokyo 171-8588, Japan; katsuto.tanaka@gakushuin.ac.jp 3.2. Kalman Filter to Estimate Parameters of Two-Factor Vasicek Model. Many scholars use the generalized moment estimate method (GMM) and maximun likelihood estimate (MLE) to estimate the parameters of Vasicek.

Therefore, it is natural to replace the Brownian motion by the Levy process In this paper, an estimate of the drift and diffusion parameters of the extended Vasiček model is presented. The estimate is based on the method of maximum likelihood.

However, some features of the ﬁnancial processes cannot be captured by the Vasicek model, for example, discontinuous sample paths and heavy tailed properties. Therefore, it is natural to replace the Brownian motion by the Levy process.

Rewriting (1.5) we have r t+ t= r t(1 t) + t+ ˙ p tN(0;1) (2.1) likelihood method will be used to estimate the parameters in the Vasicek model. At the end of thechapter, wewillalsopresentanapproachofhowtopricecapsandﬂoorsusingMonteCarlo simulations. The fourth chapter will present the results, given the methodology from previous chapters. This approach allows estimating risk premia, inflation expectations, and various parameters of models, though it suffers from overly simplistic assumptions about the dynamics of the real interest rate.
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. and Uhlenbeck (1930) ( ZO-U [) process, also known as the Vasicek (1977) process. I discuss the model briefly, including Matlab code to simulate the process. I discuss the estimation of the parameters, in particular the difficult of estimating the speed-of-mean-reversion parameter.
