This paper aims to further our understanding of the effect of idiosyncratic risk on the equity premium. We consider different classes of preferences and different co-variations between the idiosyncratic shocks’ variance and the economy’s aggregate income. We offer a complete characterization of the effect for short-lived assets relying on the cross-moments of different utility function derivatives and the economy’s aggregate income. We also study the effects of higher-order moments of the distribution of idiosyncratic risk.
