Stochastic Processes and their Applications, 2018, vol. 128, issue 3, 1034-1071
We consider a stochastic volatility model which captures relevant stylized facts of financial series, including the multi-scaling of moments. The volatility evolves according to a generalized Ornstein–Uhlenbeck processes with super-linear mean reversion.
