We introduce the Homoscedastic Gamma [HG] model where the distribution of returns is characterized by its mean, variance and an independent skewness parameter under both measures. The model predicts that the spread between historical and risk-neutral volatilities is a function of the risk...

We document the predictive ability and economic significance of global economic policy uncertainty for U.S. equity returns. After orthogonalizing global economic policy uncertainty (global EPU) with respect to the U.S. EPU, we find that it has significant predictive power for aggregate stock...
