Framework[ edit ] The key to these techniques is the recognition that the drifts of the no-arbitrage evolution of certain variables can be expressed as functions of their volatilities and the correlations among themselves. In other words, no drift estimation is needed.

Models developed according to the HJM framework are different from the so-called short-rate models in the sense that HJM-type models capture the full dynamics of the entire forward rate curve , while the short-rate models only capture the dynamics of a point on the curve the short rate.

However, models developed according to the general HJM framework are often non- Markovian and can even have infinite dimensions. A number of researchers have made great contributions to tackle this problem. They show that if the volatility structure of the forward rates satisfy certain conditions, then an HJM model can be expressed entirely by a finite state Markovian system, making it computationally feasible. Examples include a one-factor, two state model O. Ritchken and L. Mathematical formulation[ edit ] The class of models developed by Heath, Jarrow and Morton is based on modelling the forward rates, yet it does not capture all of the complexities of an evolving term structure.

The model begins by introducing the instantaneous forward rate f.
