Existence Theorems of Continuous Social Aggregation for Infinite Discrete Alternatives CHEN, Stacey H. HUANG, Wu-Hsiung https://www.grips.ac.jp/list/jp/facultyinfo/chen-stacey/ This paper considers the infinite alternative case to prove the existence of continuous social welfare aggregation that is anonymous and respects the unanimity. It clarifies the controversy between Chichilnisky (1982, QJE) and Huang for their contradictory results for the continuum case. Compared to their topological frameworks, the infinite alternative case is easier to understand and pinpoint their difference.
