We study the problem of elicitation of subjective beliefs of an agent when the beliefs are ambiguous (the set of beliefs is a non-singleton set) and the agent's preference exhibits ambiguity aversion; in particular, as represented by alpha-maxmin preferences. We construct a direct revelation...

We elicit subjective ambiguous beliefs of an agent with ambiguity-sensitive preferences; in particular, as represented by the alpha-maxmin model. An important problem with the model is that it cannot be identified using observations from typical choice problems, as the preference parameter alpha...

We derive necessary and sufficient conditions for data sets composed of state-contingent prices and consumption to be consistent with two prominent models of decision making under uncertainty: variational preferences and smooth ambiguity. The revealed preference conditions for subjective...
