Choice and Matching
研究了路径独立选择规则在匹配问题中的应用，提出了一种多对多匹配市场的延迟接受算法，并分析了选择集变化对市场各方福利的影响。
We study path-independent choice rules applied to a matching context. We use a classic representation of these choice rules to introduce a powerful technique for matching theory. Using this technique, we provide a deferred acceptance algorithm for many-to-many matching markets with contracts and study its properties. Next, we obtain a compelling comparative static result: if one agent's choice expands, the remaining agents on her side of the market are made worse off, while agents on the other side of the market are made better off. Finally, we establish several results related to path-independent choice rules.
