1) The foundation is that the short rate evolves according to a random process. This means that we cannot predict where the short rate will be at a future date, but we quantify the possible paths probabilistically. 2018-11-18 · In this paper we review the Vasicek and Hull-White 1 factor (HW1F) models. For each model we summarize the model stochastic process, solution and Gaussian or normal dynamics. For pricing purposes we might opt to use more advanced models, however for risk management and complex calculations such as XVA or Financial Review of the Trading Book (FRTB) such models remain competitive. Excel-based macroeconomic simulator. Welcome to the Macroeconomic Simulator The simulator has been designed and programmed by Javier Lozano, Lecturer in Economics, University of the Balearic Islands, using models from the book.
There are more advanced generalisations which can, and I’ll discuss some soon, but they will use all of the same tricks and algebra that I’ve covered here. Se hela listan på medium.com
For starters, the short rate model you mention in equation (1) is Cox-Ingersoll-Ross while the bond price in equations (2)-(4) correspond to the Vacisek model.

the term struc-ture has the form p(t,T) = F(t,r(t);T) (8) where F has the form F(t,r;T) = e(A(t,T)−B(t,T)r), (9) and where A and B are deterministic functions. It turns out that the existence of an aﬃne term structure is extremely pleasing from an analytical and a com- There exist several approaches for modelling the interest rate, and one of them is the so called Vasicek model, which assumes that the short rate r(t) has the dynamics where theta is the long term mean level to which the interest rate converges, kappa is the speed at which the trajectories will regroup around theta, and sigma the usual the volatility.
