Approximating the zero-coupon bond price in a general one-factor model with constant coefficients

Computational Finance 2014-08-26 v1

Abstract

We consider a general one-factor short rate model, in which the instantaneous interest rate is driven by a univariate diffusion with time independent drift and volatility. We construct recursive formula for the coefficients of the Taylor expansion of the bond price and its logarithm around τ=0\tau=0, where τ\tau is time to maturity. We provide numerical examples of convergence of the partial sums of the series and compare them with the known exact values in the case of Cox-Ingersoll-Ross and Dothan model.
