“…However, it is shown in the literature that stochastic volatility effects can be added by means of time changes (see Carr and Wu, 2007, for example); the extension to the multidimensional case is though subject of current research. Further research concerning applications of the model proposed in this paper could be the analysis of model risk, with respect to the distributions corresponding to the processes indicated in Table 1, in the context of capturing the joint dynamics of FX rates and other securities, as well as pricing multinames FX derivative contracts in the spirit of Barrieu and Scandolo (2015); Coqueret and Tavin (2016).…”

“…We use the FDHestonMEM, the characteristic function (13), and Formula (24) (COSbased method) to evaluate European puts. To test the effectiveness of the pricing method, we take the numerical integration method as a benchmark and set 64 points in Formula ( 24) and L = 10 in Formula (25).…”

“…In fact, in a setting driven by standard Brownian motions, the studies in [10][11][12] by real data suggest the real asset price is not a continuous process but jumps occasionally. Moreover, extensive empirical studies [13][14][15] show that jumps and stochastic volatilities exist in the asset price. On the one hand, compared to the other jump distribution, the mixed-exponential jump [12] is more general in approximating asset return distributions; on the other hand, the double Heston model [16] exhibits good performance in fitting the long-term "volatility smile" and "volatility clustering".…”

“…They show that uncertainty in the portfolio's dependence is a source of huge model risk. Coqueret & Tavin (2016) investigate model risk for variance swaps and forward start options in a market with jumps and stochastic volatility and measured model risk based on the worst case risk measure.…”
