“…See also Machina (1984), where it is shown that, in the case of expected utility (in the context of a static model), convexity and continuity in the distribution completely characterize the indirect utility functional, so that any functional with these properties is the indirect utility functional for some preferences. 13 See Appelbaum (1997Appelbaum ( , 2006 for a discussion and proof of continuity, convexity and monotonicity. If we do not have expected utility, H (w t , R f t , m t ) may be either convex, or concave in the moments.…”
