Note that the KWF random run follows the expected value solution more closely than the HL example did in Figure 2. This pattern is also exhibited in the binomial tree models in Chapter 3. The actual KWF model is a variation of the model we have presented. Because the actual KWF model does not explicitly incorporate the drift, the model does not always have a solution for the binomial tree. Our presentation of the KWF model, however, is easily modified to obtain the actual KWF binomial tree. Figure 5.

Because u is the same as the HL and HW processes, u can become negative, but u = ln(r) so r = eu; thus, r is always positive. Therefore, the KWF model eliminates the problems of negative short rates that occur with the HL and HW models. Taking the expectation of Equation 26a results in dln(r) = θdt, and for Equation 26b du = θdt. The expected value in Equation 14a yields ln [ r ( t ) ] = u = u ( 0 ) + ∫ t θ ds, 0 and because u(0) = ln[r(0)] = ln(r0), ln [ r ( t ) ] = ln ( r 0 ) + ∫ t θ ds . 0 Taking the exponential of both sides of this equation gives t r ( t ) = r0 e ∫0 θ ds , (27) showing that r(t) > 0 because r(0) > 0.

This condition simply requires that an up-move from a down-state equal a down-move from an up-state. For example, rud = rdu. The recombination condition reduces the number of possible short rates at t2 from 4 to 3 and at t3 from 8 to 4. The recombination condition is used at each interior node of the tree. This requirement will permit an increase of only one node from one time step to the next. So, for a 10-period tree, we only need 10 equations; and for the 30-period tree, we only need 30 equations.
