在一个简单的模型中,代理人的货币支付是不确定的,本文研究的主观期望效用函数的相互不可比较的聚合。最小社会福利准则源自效率、事后公平和社会理性公理,并结合无风险情况下信念和风险偏好的独立性(Chambers and Echenique in Games Econ Behav 76:582-595,2012)。该标准比较分配的前景组成的确定性等价物评估的状态最小收益的值。由于这种结构,标准是平等主义和风险规避。
In a simple model where agents’ monetary payoffs are uncertain, this paper examines the aggregation of subjective expected utility functions which are interpersonally noncomparable. A maximin social welfare criterion is derived from axioms of efficiency,ex postequity, and social rationality, combined with the independence of beliefs and risk preferences in riskless situations (Chambers and Echenique in Games Econ Behav 76:582–595, 2012). The criterion compares allocations by the values of the prospects composed of the statewise minimum payoffs evaluated by the certainty equivalents. Because of this construction, the criterion is egalitarian and risk averse.
