We consider a formal approach to comparative risk aversion and applies it to intertemporal choice models. This allows us to ask whether standard classes of utility functions, such as those inspired by Kihlstrom and Mirman [15], Selden [26], Epstein and Zin [9] and Quiggin [24] are well-ordered...

We study how risk aversion affects precautionary savings when considering monotone recursive Kreps-Porteus preferences. In a general infinite-horizon setting, we prove that risk aversion unambiguously increases precautionary savings. The result is derived without specifying income uncertainty,...

We formulate and estimate a tractable macroeconomic model with time-varying precautionary savings. We argue that the latter affect aggregate fluctuations via two main channels: a stabilizing aggregate supply effect working through the supply of capital; and a destabilizing aggregate demand...

We construct, and then estimate by maximum likelihood, a tractable dynamic stochastic general equilibrium model with incomplete insurance and heterogenous agents. The key feature of our framework is that cross-sectional heterogeneity remains finite dimensional. The solution to the model thus...
