Web4 3. The 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. Web36 6. TWO-FACTOR SHORT-RATE MODELS Theorem 6.11 (Forward-rate dynamics in the G2++ model).

WebOther short rate models Two-factor Hull-White model In the two-factor Hull-White model, the instantaneous rate is represented as the sum of (i)the current rate r0 (t), and (ii)two stochastic state variables r1 (t) and r2 (t). In other words, r (t) = r0 (t) + r1 (t) + r2 (t). A natural interpretation of these variables is that r1 (t) controls ...
