Eduardo Abi Jaber, Camille Illand and Shaun (Xiaoyuan) Li present a simple model to jointly fit the SPX-VIX smiles with only six effective parameters and an input curve that allows matching of certain term structures. The model remains tractable for pricing and calibration: the VIX squared is polynomial in the Ornstein-Uhlenbeck process, leading to efficient VIX derivative pricing by a simple integration with respect to a Gaussian density.
