Simulation of the drawdown and its duration in Lévy models via stick-breaking Gaussian approximation
Jorge González Cázares, Aleksandar Mijatović
We develop a computational method for expected functionals of the drawdown and its duration in exponential Lévy models. It is based on a novel simulation algorithm for the joint la…
Joint density of a stable process and its supremum: regularity and upper bounds
Jorge González Cázares, Arturo Kohatsu Higa, Aleksandar Mijatović
This article uses a combination of three ideas from simulation to establish a nearly optimal polynomial upper bound for the joint density of the stable process and its associated s…
Large and moderate deviations for stochastic Volterra systems
Antoine Jacquier, Alexandre Pannier
We provide a unified treatment of pathwise Large and Moderate deviations principles for a general class of multidimensional stochastic Volterra equations with singular kernels, not…
Recovering Brownian and jump parts from high-frequency observations of a Lévy process
Jorge González Cázares, Jevgenijs Ivanovs
We introduce two general non-parametric methods for recovering paths of the Brownian and jump components from high-frequency observations of a Lévy process. The first procedure rel…
Reflecting random walks in curvilinear wedges
Mikhail V. Menshikov, Aleksandar Mijatović, Andrew R. Wade
We study a random walk (Markov chain) in an unbounded planar domain whose boundary is described by two curves of the form and , with $x_…
