The term structure of the price of variance risk
We empirically investigate the term structure of variance risk pricing and how it varies over time. We estimate the aversion to variance risk in a stochastic-volatility option pricing model separately for options of different maturities and find that variance risk pricing decreases in absolute value with maturity but remains significantly different from zero up to the nine-month horizon. We find consistent non-parametric results using estimates from Sharpe ratios of delta-neutral straddles. We further show that the term structure is downward sloping both during normal times and in times of ...

Horizon-Dependent Risk Aversion and the Timing and Pricing of Uncertainty
Inspired by experimental evidence, we amend the recursive utility model to let risk aversion decrease with the temporal horizon. Our pseudo-recursive preferences remain tractable and retain appealing features of the long-run risk framework, notably its success at explaining asset pricing moments. In addition, our model addresses two challenges to the standard model. Calibrating the agents’ preferences to explain the equity premium no longer implies an extreme preference for early resolutions of uncertainty. Horizondependent risk aversion helps resolve key puzzles in finance on the valuation ...
