论文摘要
在许多现实世界中的匹配应用程序中，机构对其老虎机的优先级或对其他插槽（或两者兼而有之的未填充插槽的可传递性）都有限制。本文在此类现实生活中的匹配问题中需要的激励，制定了一个实用选择规则，特定于容量转移的插槽优先级（SSPWCT）。这些实用规则调用了特定于插槽的优先级结构和空置插槽的可转移性。我们表明，累积报价机制（COM）是稳定的，防止策略的，并且尊重有关SSPWCT选择规则的改进。传递一个又一个未填充的插槽的容量，而其他所有内容都是恒定的，从而导致COM的策略帕累托改进。按照Kominer（2020）的配方，我们还提供了比较静态结果，以扩大分支机构的能力并在SSPWCT框架中增加新合同。我们的结果对具有多样性考虑的资源分配问题有影响。
In many real-world matching applications, there are restrictions for institutions either on priorities of their slots or on the transferability of unfilled slots over others (or both). Motivated by the need in such real-life matching problems, this paper formulates a family of practical choice rules, slot-specific priorities with capacity transfers (SSPwCT). These practical rules invoke both slot-specific priorities structure and transferability of vacant slots. We show that the cumulative offer mechanism (COM) is stable, strategy-proof and respects improvements with regards to SSPwCT choice rules. Transferring the capacity of one more unfilled slot, while all else is constant, leads to strategy-proof Pareto improvement of the COM. Following Kominer's (2020) formulation, we also provide comparative static results for expansion of branch capacity and addition of new contracts in the SSPwCT framework. Our results have implications for resource allocation problems with diversity considerations.
