volatility risk. While pointing out the joint pricing kernel is not identified nonparametrically, we propose model-free estimates … of marginal pricing kernels of the market return and volatility conditional on the VIX. We find that the pricing kernel … present a U-shape. Hence, stochastic volatility is the key state variable responsible for the U-shape puzzle documented in the …

nature of the answer when the volatility differential is due to the systematic/priced risk. Here the difference in the … direction and magnitude of the net effect depends on the levels of asset beta and volatility and the moneyness and maturity of … nonlinear derivatives, one should pay attention to the source of volatility differential, and the sample range/mix of betas …

An anchoring-adjusted option pricing model is developed in which the volatility of the underlying stock return is used … as a starting point that gets adjusted upwards to form expectations about call option volatility. I show that the …

The aim of this paper is twofold: to investigate how the information content of implied volatility varies according to … moneyness and option type and to compare option-based forecasts with historical volatility. The different information content of … implied volatility is examined for the most liquid at-the-money and out-of-the-money options: put (call) options for strikes …

straddles; second, we estimate the PVR in a Heston (1993) stochastic-volatility model. In both cases, the estimation is … more negative and its term structure is steeper when volatility is high. These findings are inconsistent with calibrations …
