How to Control Controlled School Choice: Comment
指出Echenique和Yenmez（2015）定理2中“仅当”部分有误，给出了一个反例，并修正了公理和结论。
Echenique and Yenmez (2015), in Theorem 2, characterize choice rules that are “generated by reserves for the priority.” We show that the “only if” part is not correct. We exhibit a choice rule that is generated by reserves for the priority but violates one of their axioms. We reformulate the axiom and repair the result.
