Characterizing a probabilistic version of the Boston mechanism under weak priorities
刻画了Han(2024)提出的波士顿机制概率版本，该机制唯一满足尊重排名、等秩事前稳定性和等秩等优先级序数公平性，并在所有等秩事前稳定分配中唯一选出基于排名的leximin最优分配。
We characterize the probabilistic version of the Boston mechanism from Han (2024). This mechanism uniquely satisfies respect for rank, equal-rank ex-ante stability, and equal-rank equal-priority ordinal fairness. Additionally, it uniquely selects the rank-based leximin-optimal allocation among all equal-rank ex-ante stable allocations.
