Long-time trajectorial large deviations for affine stochastic volatility models and application to variance reduction for option pricing
Zorana Grbac, David Krief, Peter Tankov
This work extends the variance reduction method for the pricing of possibly path-dependent derivatives, which was developed in (Genin and Tankov, 2016) for exponential Lévy models,…

Long-time large deviations for the multi-asset Wishart stochastic volatility model and option pricing
Aurélien Alfonsi, David Krief, Peter Tankov
We prove a large deviations principle for the class of multidimensional affine stochastic volatility models considered in (Gourieroux, C. and Sufana, R., J. Bus. Econ. Stat., 28(3)…
