Collective choice rules on restricted domains based on a priori information
研究了每个个体拥有包含某种偏序的偏好域时，这些受限域存在一致、防策略且非独裁的选择规则的充要条件。
Abstract We consider restricted domains where each individual has a domain of preferences containing some partial order. This partial order might differ for different individuals. Necessary and sufficient conditions are formulated under which these restricted domains admit unanimous, strategy-proof and non-dictatorial choice rules.
