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. Estimating the price of variance risk in a stochastic-volatility option pricing model separately for options of different maturities, we find a price of variance risk that decreases in absolute value with maturity but remains significantly different from zero up to the nine-month horizon. We show that the term structure is consistently downward sloping both during normal times and in times of stress, when required compensation for variance risk increases and its term structure steepens further.

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 ...
