High Order Weak Approximation Schemes for Lévy-Driven SDEs [chapter]

Peter Tankov
2012 Monte Carlo and Quasi-Monte Carlo Methods 2010  
In the case of Lévy processes with stablelike behavior of small jumps, we construct schemes with arbitrarily high rates of convergence by matching a sufficiently large number of moments.  ...  The idea is to replace the driving Lévy process Z with a finite intensity process which has the same Lévy measure outside a neighborhood of zero and matches a given number of moments of Z.  ...  It is interesting to compare the convergence rates for our jump-adapted moment matching scheme (6-7) with the convergence rates for the classical Euler scheme, known from the literature.  ...
