Two-Moment Decision Models and Expected Utility Maximization
发现了一个新的限制条件，使得两矩决策模型与期望效用最大化一致，并验证了该条件在许多经济模型中成立，进而推导出对矩模型分析的意义。
Two-moment decision models are consistent with expected utility maximization only if the choice set or the agent's preferences are restricted. All currently available restrictions, such as quadratic utility or normality, are either theoretically deficient and/or empirically rejected. This paper identifies another restriction which is sufficient to ensure consistency between the two approaches and confirms that it holds in many economic models. Implications of this restriction for moment model analysis are then derived. Copyright 1987 by American Economic Association.
