This paper experimentally studies comparative properties of risk aversion and ambiguity aversion in the way that the role of heterogeneity is allowed for. We examine correlation between the degrees of risk aversion and the degree of ambiguity aversion, how the latter changes across geometric properties of objective sets of possible probability distributions and how ambiguous information is generated.Appendix: How to generate imprecise information in the dice experiment [27
