The MertonJumpDiffusion command creates a new jump diffusion process that is governed by the stochastic differential equation (SDE)

where

 is the drift parameter

 is the volatility parameter

 is the standard Wiener process

and

 is a compound Poisson process of the form

such that  is independent and lognormally distributed with mean  and standard deviation .

Both the drift parameter mu and the volatility parameter sigma can be either constant or time-dependent. In the second case they can be specified either as an algebraic expression containing one indeterminate, or as a procedure that accepts one parameter (the time) and returns the corresponding value of the drift (volatility).

Similar to the drift and the volatility parameters, the intensity parameter lambda can be either constant or time-dependent. In the second case it can be specified either as an algebraic expression containing one indeterminate or as a procedure that accepts one parameter (the time).

Both the scale parameter a and the shape parameter b of the underlying lognormal Poisson process must be real constants.

The Finance[MertonJumpDiffusion] command was introduced in Maple 15.
