Are Universal Preferences Possible? Calibration Results for Non-Expected Utility Theories
Rabin proved that a low level of risk aversion with respect to small gambles leads to a high, and absurd, level of risk aversion with respect to large gambles. Rabin's arguments strongly depend on expected utility theory, but we show that similar arguments apply to almost all non-expected utility theories and even to theories dealing with uncertainty. The set of restrictions needed in order to avoid such absurd behavior may suggest that the assumption of universality of preferences over final wealth is too strong.
