Sufficientarianism
用公理方法分析充足主义，提出三个核心准则的特征化，揭示其优先最差群体与对平等无差异的混合性质，适合研究分配正义的经济学者参考。
Sufficientarianism is a prominent approach to distributive justice in political philosophy and in policy analyses. However, it is virtually absent from the formal normative economics literature. We analyze sufficientarianism axiomatically in the context of the allocation of 0–1 normalized well‐being in society. We present three characterizations of the core sufficientarian criterion, which counts the number of agents who attain a “good enough” level of well‐being. The main characterization captures the “hybrid” nature of the criterion, which embodies at the same time a threshold around which the worst off in society is prioritized, and an indifference to equality in other regions. The other two characterizations relate sufficientarianism, respectively, to a liberal principle of noninterference and to a classic neutrality property.
