A simple joint model for returns, volatility and volatility of volatility

open access: yesJournal of Econometrics, 2023
Abstract We propose a model that allows for conditional heteroskedasticity in the volatility of asset returns and incorporates current return information into the volatility nowcast and forecast. Our model can capture all stylised facts of asset returns even with Gaussian innovations and is simple to implement.
