社会选择中的信息基础的概念可以扩大，以便不仅涵盖与人际效用比较相关的标准概念，而且还包括有关相关替代品的效用或偏好、替代品的非效用特征、个人责任、无关子群体和可行性约束的信息。本文提出了一个统一的概念框架，所有这些概念，并分析了在每种情况下保留的信息。这个新的框架使我们对社会选择的困难和可能性有了更深的理解。并得到了新的福利主义定理。
The notion of informational basis in social choice can be broadened so as to cover not only the standard notions related to interpersonal utility comparisons, but also information about utilities or preferences at (ir)relevant alternatives, non-utility features of alternatives, personal responsibility, unconcerned subpopulations, and feasibility constraints. This paper proposes a unified conceptual framework for all these notions, and analyzes the kind of information retained in each case. This new framework yields a deeper understanding of the difficulties and possibilities of social choice. New welfarism theorems are also obtained.
