%0 Journal Article %T How to make Dupire's local volatility work with jumps %A Peter K. Friz %A Stefan Gerhold %A Marc Yor %J Quantitative Finance %D 2013 %I arXiv %X There are several (mathematical) reasons why Dupire's formula fails in the non-diffusion setting. And yet, in practice, ad-hoc preconditioning of the option data works reasonably well. In this note we attempt to explain why. In particular, we propose a regularization procedure of the option data so that Dupire's local vol diffusion process recreates the correct option prices, even in manifest presence of jumps. %U http://arxiv.org/abs/1302.5548v1
