Abstract
In the present paper, we compute the Greeks for a class of jump diffusion models by using Malliavin calculus techniques. More precisely, the model under consideration is governed by a Brownian component and a jump part described by a compound Poisson process. Our approach consists of approximating the compound Poisson process by a suitable sequence of standard Poisson processes. The Greeks of the original model are obtained as limits or weighted limits of the Greeks of the approximate model. We illustrate our results by the computation of the Greeks for digital options in the framework of the Merton model. The technique of Malliavin weights is found to be efficient compared to the finite difference approach.
