Cash flow and risk premium dynamics in an equilibrium asset-pricing model with recursive preferences
Under linear approximations for asset prices and the assumption of independence between expected consumption growth and time-varying volatility, long-run risks models imply constant market prices of risks and often generate counterfactual results about asset return and cash ?ow predictability. We develop and estimate a nonlinear equilibrium asset pricing model with recursive preferences and a ?exible econometric speci?cation of cash ?ow processes. While in many long-run risks models time-varying volatility in?uences only risk premium but not expected cash ?ows, in our model a common set of ...

Explaining World Savings
Saving rates are significantly different across countries and remain different for long periods of time. This paper provides an explanation for this phenomenon. We formalize a model of a world economy comprised of open economies inhabited by heterogeneous agents endowed with recursive preferences. Our assumed preferences imply increasing marginal impatience of agents as their consumption rises relative to average consumption of a reference group. Using measured productivity as the sole exogenous driver, we show that the model can not only reproduce the sustained long run differences in ...
