“…A large literature on affine stochastic volatility models has emerged focusing on improving the path-breaking model of Heston (1993): models that allow for jumps in the dynamics of the price of the financial asset, in order to account for large moves such in the case of crashes (Bates, 1996;Bakshi, Cao and Chen, 1997), models allowing that the long-run variance is itself a stochastic process, modeled as a diffusion process or as a discrete state Markov process (Bardgett, Gourier and Leippold, 2013;Kaeck and Alexander, 2012), models that allow for jumps in the dynamics of the variance (Eraker, 2004;Broadie, Chernov and Johannes, 2007), two-factor models that generates stochastic correlation between returns and volatility (Christoffersen, Heston and Jacobs, 2009), or three-factor models with jumps both in the dynamics of the underlying and of the volatility (Andersen, Fusari and Todorov, 2015).…”
