This paper shows that non-linearities can generate time-varying and asymmetric
risk premia over the business cycle. These (empirical) key features become relevant and
asset market implications improve substantially when we allow for non-normalities in
the form of rare disasters. We employ explicit solutions of dynamic stochastic general
equilibrium models, including a novel solution with endogenous labor supply, to obtain
closed-form expressions for the risk premium in production economies. We find that
the curvature of the policy functions affects the risk premium through controlling the
individual's effective risk aversion.
