Final published version
A new utility kernel for Epstein-Zin-Weil preferences is proposed to disentangle the intertemporal elasticity of substitution (IES), the relative risk aversion (RRA), and the timing attitude. These new preferences resolve two puzzles in the long-run risk model, where consumption growth is too strongly correlated with the price-dividend ratio and the risk-free rate. The proposed preferences also enable a New Keynesian model to match equity and bond premia with a low RRA of 5. Importantly, the mechanism enabling Epstein-Zin-Weil preferences to explain asset prices in these models is not to separate the IES from RRA, but to introduce a strong timing attitude.
