Experts often disagree. A decision-maker may be averse to such expert disagreement. Existing models of aversion to expert disagreement rest on ambiguity-averse preferences adopting a unanimity principle: If all experts consider one choice better than another, so should the decision-maker. Such...

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 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...
