Two-Class Voting: A Mechanism for Conflict Resolution
研究将选民分为两个阶层、每层分别多数通过的两阶层投票机制，发现当利益冲突显著且两派人数相当时，该机制比单层投票更能有效聚合分散信息，但无冲突时效率较低。
We discuss two-class voting procedures where voters are divided into classes and a separate majority is required in each class. Examples include Chapter 11 bankruptcy proceedings and some political mechanisms. We investigate how voting mechanisms aggregate information dispersed among voters when voters have conflicts of interests as well as different information regarding a proposal. We find that two-class voting provides a significant improvement over one-class voting in all situations where voters have significant conflicts of interests, and where the voters are relatively evenly divided between interest groups. However, two-class voting is inefficient absent conflicts of interests.
