Hi all, for my study I am doing a project where I have to study the convergence rate of a Euler scheme for a SDE driven by a levy process. This a very simple one, namely:dS/S = dZwhere Z is a Levy process of infinite activity. I have to do that for different Levy measures, and compute the price of a call optionE(h(S_T))This is why I was wondering if there exist closed form formulae available for some Levy measure ?thank you very much!

There might be many others, but I only come across these two.

depends what you mean by closed form - VG typically uses numerical integration and DEJD uses inversion of Laplace transform - though values are quick and accurate they're not as simple as say the Black-Scholes formula

Black-Scholes formula uses numerical integration, as well.

You should have a look at the two books :- Cont, Tankov- Schoutens
