Dynamic Hedging: Managing Vanilla And Exotic Op... !!BETTER!!
LV models work well for vanilla products pricing, but are unsuitable for capturing the smile dynamics, which is necessary for exotic path-dependent products such as autocallables. Reghai and Monciaud hit upon the idea of starting with the LV model to build the LSV model.

That can be done by perturbing the parameters of the model to assess the impact of the smile dynamics on the P&L. In the case of LV and LSV, it turns out that a standard perturbation approach would cause undesirable effects when pricing vanilla products. Because LV is already a good pricer for vanilla products, additional terms that are supposed to be non-zero are likely to affect the calibration. Reghai and Monciaud found a novel solution to the problem. 041b061a72
