The Gaussian affine interest rate models are widely used in the financial industry for pricing, hedging and also risk management purposes. We consider the multifactor models with time dependent parameters. Usually the models are simulated using some appropriate discretization schema because the...

Abstract. This paper describes how an efficient and exact Monte-Carlo simulation of the Hull-White model could be performed. For that purpose the joint conditional distribution of the short interest rate and the discount factor is derived. The proposed approach can be straightforward extended to...
