摘要：Implicit in most applications of the expected utility (EU) model is the assumption that only the decision maker's own income matters. Moreover, studies that estimate risk preferences typically measure how individuals respond to changes in the level and likelihood of having their own income altered (Young). The focus on own income in the EU model is consistent with the assumption most often applied in the neoclassical economic paradigm; namely, that the identity of participants in an economic exchange does not affect the outcome (Telser and Higinbotham).
