Being particular about calibration
Following previous work on the calibration of multi-factor local stochastic volatility models to market smiles, Julien Guyon and Pierre Henry-Labordère show how to calibrate exactly any such model. Their approach, based on McKean’s particle method,…

Smooth calibration of Markov functional models for pricing exotic interest rate derivatives
The Libor market model is widely used but often criticised for its slowness. Nick Denson and Mark Joshi develop an accurate and stable calibration procedure that allows for the effective use of a control variate
Capturing the smile
Since the discovery that traditional calibration methods fail to capture the dynamics of the smile, new approaches based on mixtures or ensembles of models have been developed. Simon Johnson and Han Lee present a variant of this approach that can be used…
