Two factor vasicek model
WebJan 19, 2024 · The Vasicek Model is a one-factor mean reversion model where the short-term interest rate converges to a steady state value, r 0. This model was introduced by Czech mathematician, Oldrich Alfons Vasicek, in his 1977 paper, “An Equilibrium Characterization of the Term Structure. ... WebThe Two-Factor Hull-White Model. As explained in Hull-White One factor model, the risk-neutral process for the short rate, r, is. df ()r = [θ (t)+ u − af (r)]dt + σ 1dz1 where u has an initial value of zero and follows the process. du = −budt +σ 2dz2. The parameter θ (t) is a deterministic function of time.
