Abstract We prove a natural comparative static for many-to-many matching markets in which agents’ choice functions exhibit size-dependent discounts: reducing the extent to which some agent discounts additional partners leads to improved outcomes for the agents on the other side of the market, and worsened outcomes for the agents on the same side of the market. Our argument draws upon recently developed methods bringing tools from choice theory into matching.

匹配市场中规模相关折扣的比较静态

摘要 我们证明了多对多匹配市场的自然比较静态，其中代理人的选择函数表现出与规模相关的折扣：减少某些代理人对额外合作伙伴的折扣程度会导致另一端代理人的结果有所改善。市场的同一侧的代理商的结果恶化。我们的论点借鉴了最近开发的方法，将选择理论的工具引入匹配。
