This paper proposes that the ambiguity reflected by a set of priors remains unchanged when the set is translated within … the probability simplex, i.e. ambiguity is location invariant. This unifies and generalises numerous influential … definitions of ambiguity in the literature. Location invariance is applied to normal form games where players perceive strategic …

In Ghirardato, Macheroni and MArcinaccri (GMM) propose a method for distinguishing between percieved ambiguity and the … subclass of a-MEU preferences. We show that for Hurwicz preferences the proposed measure of ambiguity depends on parameters … which intuitively reflect ambiguity-attitude. Furthermore, any a-MEU preferences which satisfy the CEU axioms, satisfy GMM …
