Generalized Disappointment Aversion and the Variance Term Structure

Abstract

Contrary to leading asset pricing theories, recent empirical evidence indicates that financial markets compensate only short-term equity variance risk. An equilibrium model with generalized disappointment aversion risk preferences and rare events reconciles salient features of the variance term structure. In addition, a calibration explains the variance and skew risk premiums in equity returns and the implied volatility skew of index options while capturing standard moments of fundamentals, equity returns, and the risk-free rate. The key intuition for the results stems from substantial countercyclical risk aversion induced by endogenous variation in the probability of disappointing events in consumption growth.
