Chapter 9
The Heath, Jarrow, Morton Model

Written in 1994; printed in Economic Notes, 36 (3) (2008), 205–207.

The price c09-math-0001 at time τ of a discount bond maturing at T is subject to the dynamics

equation

with

equation

where c09-math-0004 is the market price of risk (see Vasicek, 1977, Chapter 6 of this volume). This can be written as

1 equation

where

equation

Integrate Eq. (1) with respect to τ from 0 to t,

equation

and differentiate with respect to T. This produces

2 equation

where σF is the volatility of the forward rates and

equation

Eq. (2) is the Heath, Jarrow, Morton (1992) model.

If c09-math-0010 are vectors, their products are interpreted as inner products.
