Volatility-of-Volatility Risk, with Ivan Shaliastovich
Abstract: We show time-varying volatility of volatility is a significant risk factor which affects the cross-section and time-series of index and VIX option returns, beyond volatility risk itself. Volatility and volatility-of-volatility movements are identified model-free from index and VIX options, corresponding to VIX and VVIX indices respectively. Delta-hedged index and VIX option returns are negative on average, and more negative for strategies more exposed to volatility and volatility-of-volatility risks. Volatility and volatility of volatility significantly and negatively predict future delta-hedged returns. The evidence is consistent with a no-arbitrage model featuring time-varying volatility and volatility-of-volatility factors which are negatively priced by investors.

Risk Adjustment and the Temporal Resolution of Uncertainty: Evidence from Options Markets, with Ivan Shaliastovich
Abstract: Risk-neutral probabilities, observable from option prices, combine objective probabilities and risk adjustments across economic states. We consider a recursive-utility framework to separately identify objective probabilities and risk adjustments using only observed market prices. We find that a preference for early resolution of uncertainty plays a key role in generating sizeable risk premia to explain the cross-section of risk-neutral and objective probabilities in the data. Failure to incorporate a preference for the timing of the resolution of uncertainty (e.g., expected utility models) can significantly overstate the implied probability of, and understate risk compensations for, adverse economic states.
