委员会偏好下的匹配

Matching with Committee Preferences

Haoyu Song, Thanh Nguyen, Young-san Lin

AI总结:

本文研究了基于学校选择的多对一匹配模型,通过社会选择准则模拟学校评估过程,定义可接受选择并构建近似稳定匹配框架。

摘要:

我们研究了一个受学校选择启发的多对一匹配模型,其中学校使用多个排名而非单一优先级顺序来评估申请人。我们通过社会选择准则建模每所学校的评估过程。特别是,我们将可接受的选择定义为被足够多的评估者评为接受群体中前百分之一的候选人。稳定性则基于可接受性:被接受的候选人必须获得强有力的支持,而被拒绝的候选人最多获得弱支持。由于精确的可接受性和稳定性可能不存在,我们通过结合匹配与序数偏好上的 Lindahl 均衡构造近似稳定的结局,提供了一个灵活的基于均衡的委员会匹配市场框架。

英文摘要:

We study a many-to-one matching model inspired by school choice, where schools evaluate applicants using multiple rankings rather than a single priority order. We model each school's evaluation with social choice criteria to reflect the school's internal ranking process. In particular, we define acceptable choices as candidates ranked above a top percentile of the accepted cohort by a sufficient number of evaluators. Stability is then defined in terms of acceptability: accepted candidates must receive strong support, while rejected candidates receive at most weak support. Since exact acceptability and stability may not exist, we construct approximately stable outcomes using a new equilibrium concept that combines matching with a Lindahl equilibrium over ordinal preferences, providing a flexible, equilibrium-based framework for committee-based matching markets.
