Precautionary Saving Behaviour under Ambiguity

Abstract

This paper analyses a two-period model in which a consumer faces a future income risk but is uncertain about its probability distribution. We derive three sets of sufficient conditions under which a consumer with generalised recursive smooth ambiguity (GRSA) preferences will save more under ambiguity than in a deterministic environment. Our results show how precautionary saving is jointly determined by attitudes toward atemporal risk, ambiguity and intertemporal substitution. We also find a close connection between risk prudence under non-expected utility and precautionary saving under GRSA preferences.
