Non-Expected Utility in Macroeconomics


  • Philippe Weil

    (OFCE - Observatoire français des conjonctures économiques (Sciences Po) - Sciences Po - Sciences Po)


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.
