Ellsberg's 2-color experiment, bid-ask behavior and ambiguity

Results in this note relate the observation of an interval of prices at which a DM strictly prefers to hold a zero position on an asset (termed 'bid-ask behavior') to the DM's perception of the underlying payoff relevant events as ambiguous, as the term is defined in Epstein and Zhang...

description Results in this note relate the observation of an interval of prices at which a DM strictly prefers to hold a zero position on an asset (termed 'bid-ask behavior') to the DM's perception of the underlying payoff relevant events as ambiguous, as the term is defined in Epstein and Zhang (2001). The connection between bid-ask behavior and ambiguity is established without invoking a parametric preference form, such as the Choquet expected utility or the max-min multiple priors model. This allows us to draw an observable distinction between bid-ask behavior that may arise purely due to first-order risk aversion type effects, such as those which could arise even if preferences were probabilistically sophisticated, and the bid-ask behavior that involve ambiguity perceptions.
