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 study elicitation of subjective beliefs of an agent facing ambiguity (model uncertainty): the agent has a non-singleton set of (first-order) priors on an event and a second-order distribution on these priors. Such a two-stage decomposition of uncertainty and non-reduction of subjective...

We study elicitation of subjective beliefs of an agent facing ambiguity (model uncertainty): the agent has a non-singleton set of (first-order) priors on an event and a second-order prior on these first-order belief-states. Such a two-stage decomposition of uncertainty and non-reduction of...

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...
