How to choose a fair delegation?
研究如何选择代表社会的代表团，提出基于帕累托最优、一致性、中立性和非操纵性的阈值规则，该规则根据社会异质性决定代表团规模，确保包容性，例如两人代表团需获得至少75%社会支持。
Abstract This paper analyzes how to choose a delegation, a committee to represent a society such as in a peace conference. We propose normative conditions and seek Pareto optimal, consistent, neutral, and non-manipulable ways to choose a delegation. We show that a class of threshold rules is characterized by these criteria. The rules do not choose a fixed number of delegates, but instead require different sizes of delegations, depending on the heterogeneity in society. Therefore the resulting delegations are very inclusive, and with t delegates the ratio of individuals whose opinions are not included is always below "Equation missing"<!-- image only, no MathML or LaTex -->. For instance, a delegation of size two should have at least 75% support from the society and therefore only less than 25% of the opinion pool can be neglected.
