文章摘要：Individuals behave differently when they know the objective probability of events and when they do not. The smooth ambiguity model accommodates both ambiguity (uncertainty) and risk. For an incomplete, competitive asset market, we develop a revealed preference test for asset demand to be consistent with the maximization of smooth ambiguity preferences, and we give sufficient conditions for the asset demand generated by smooth ambiguity preferences to identify the ambiguity and risk indices. We do not assume ambiguity beliefs are known: they may not even be defined, and an ambiguity free asset plays an important role for identification.
