Non-Expected Utility in Macroeconomics
Résumé
This paper introduces, within the context of an infinite optimal consumption problem, a parametric class of Kreps-Porteus nonexpected utility preferences--generalized isoelastic utility--which distinguishes attitudes toward risk from behavior toward intertemporal substitution. Some of the theoretical and empirical implications for macroeconomics of these state- and time-nonseparable preferences are examined.
