Towards this end, we use Malliavin calculus techniques for Lévy processes based on Løkka (2004), Petrou (2006), and Solé, Utzet and Vives (2007).application/pdfengL'accés als continguts d'aquest document queda condicionat a l'acceptació de les condicions d'ús establertes per la següent llicència Creative CommonsA Hull and White formula for a general stochastic volatility jump-diffusion model with applications to the study of the short-time behavior of the implied volatilityinfo:eu-repo/semantics/workingPaperhull and white formulamalliavin calculusito’s formula for the skorohod integraljumpdiffusion stochastic volatility modelsStatistics, Econometrics and Quantitative Methodsinfo:eu-repo/semantics/openAccess
