摘要 本文研究了追求效率和公正诉求的规制者在消费者收入信息不完备环境下的定价机制设计问题,着重探讨了公正诉求是否可能导致最优边际价格递增。信息不对称使得实现公正诉求须基于不损害消费者利益的前提上。在效率、公正诉求和市场完全覆盖要求下,紧闭类型域内的非端点类型消费者的边际价格超过边际成本,端点类型消费者按边际成本定价;更重要的是,如果概率分布均匀以及偏好和主观福利判断等因素满足一定条件,那么最优价格随类型先递增后递减。基于实例将类型域确定性上边界放松至正无穷,公正诉求将使递增定价机制全局最优。半福利主义诉求与类型域无上边界确实可能导致价格递增。连续递增定价机制的理论探索为探讨递增阶梯定价产生的理论依据提供了前期准备,也说明连续递增定价一定程度上能作为缓解社会不公正的一种手段。
