چکیده
THIS SUPPLEMENT CONTAINS results identifying the relevant measures and implications of comparative ambiguity aversion for Continuous Symmetric versions of several additional models from the ambiguity literature: the extended MEU with contraction model (see, e.g., Gajdos, Hayashi, Tallon, and Vergnaud (2008), Gajdos, Tallon, and Vergnaud (2004), Kopylov (2008), Tapking (2004)), the vector expected utility model (see Siniscalchi (2009)), and the second-order Choquet representation (see Amarante (2009)) of invariant biseparable preferences (defined by Ghirardato, Maccheroni, and Marinacci (2004)). It concludes by describing a technique for identifying relevant measures in additional models.
