Abstract: The information content of the S\& P 500 and VIX markets on the volatility of the S\& P 500 returns is studied. We estimate a flexible affine model based on a joint time series of underlying indexes and option prices on both markets. An extensive model specification analysis reveals that jumps and a stochastic level of reversion for the variance help reproduce risk-neutral distributions as well as the term structure of volatility smiles and of variance risk premia. We find that the S\& P 500 and VIX derivatives prices are consistent in times of market calm but contain conflicting information on the variance during market distress.
