How to Control Controlled School Choice
研究了学校在偏好学生多样性时如何设计选择规则，以兼顾稳定匹配与多样性目标，并比较了不同规则下的学生福利。
We characterize choice rules for schools that regard students as substitutes while expressing preferences for a diverse student body. The stable (or fair) assignment of students to schools requires the latter to regard the former as substitutes. Such a requirement is in conflict with the reality of schools’ preferences for diversity. We show that the conflict can be useful, in the sense that certain unique rules emerge from imposing both considerations. We also provide welfare comparisons for students when different choice rules are employed.
