Intertemporal utility smoothing under uncertainty

Author

  • Katsutoshi Wakai

Abstract

This paper axiomatizes a recursive utility model that captures both intertemporal utility smoothing defined across time and ambiguity aversion defined over states. The resulting representation adapts Wakai (Econometrica 76:137–153, 2008 ) model of intertemporal utility smoothing as an aggregator function, where the utility of the certainty equivalent of future uncertainty is computed by Gilboa and Schmeidler (J Math Econ 18:141–153, 1989 ) multiple-priors utility. The model also permits the separation of intertemporal utility smoothing from ambiguity aversion. Copyright Springer Science+Business Media New York 2013
