Multilevel Monte Carlo for exponential Lévy models
نویسندگان
چکیده
We apply the multilevel Monte Carlo method for option pricing problems using exponential Lévy models with a uniform timestep discretisation. For lookback and barrier options, we derive estimates of the convergence rate of the error introduced by the discrete monitoring of the running supremum of a broad class of Lévy processes. We then use these to obtain upper bounds on the multilevel Monte Carlo variance convergence rate for the Variance Gamma, NIG and α-stable processes. We also provide analysis of a trapezoidal approximation for Asian options. Our method is illustrated by numerical experiments.

Randomisation and recursion methods for mixed-exponential Lévy models, with financial applications
We develop a new Monte Carlo variance reduction method to estimate the expectation of two commonly encountered path-dependent functionals: first-passage times and occupation times of sets. The method is based on a recursive approximation of the first-passage time probability and expected occupation time of sets of a Lévy bridge process that relies in part on a randomisation of the time paramete...
متن کاملA transform approach to compute prices and greeks of barrier options driven by a class of Lévy processes
In this paper we propose a transform method to compute the prices and greeks of barrier options driven by a class of Lévy processes. We derive analytical expressions for the Laplace transforms in time of the prices and sensitivities of single barrier options in an exponential Lévy model with hyper-exponential jumps. Inversion of these single Laplace transform yields rapid, accurate results. The...
متن کاملApplying the Wiener-Hopf Monte Carlo Simulation Technique for Lévy processes to Path Functionals such as First Passage Times, Undershoots and Overshoots
In this note we apply the recently established Wiener-Hopf Monte Carlo (WHMC) simulation technique for Lévy processes from Kuznetsov et al. [17] to path functionals, in particular first passage times, overshoots, undershoots and the last maximum before the passage time. Such functionals have many applications, for instance in finance (the pricing of exotic options in a Lévy model) and insurance...
متن کاملPolynomial processes and their applications to mathematical finance
We introduce a class of Markov stochastic processes called mpolynomial, for which the calculation of (mixed) moments up to order m only requires the computation of matrix exponentials. This class contains affine processes, Feller processes with quadratic squared diffusion coefficient, as well as Lévy-driven SDEs with affine vector fields. Thus, many popular models such as the classical Black-Sc...
متن کاملAsian options and stochastic volatility
In modern asset price models, stochastic volatility plays a crucial role in order to explain several stylized facts of returns. Recently, [3] introduced a class of stochastic volatility models (so called BNS SV model) based on superposition of Ornstein-Uhlenbeck processes driven by subordinators. The BNS SV model forms a flexible class, where one can easily explain heavy-tails and skewness in r...
