我们通过实验测试了Gale-Shapley延迟接受（DA）机制与两个版本的迭代延迟接受机制（IDAM），其中学生一次提交一个申请。在IDAM下获得稳定结果的比例明显高于DA。这种差异可以解释为在迭代机制下遵循均衡诚实策略的被试比例高于在DA机制下遵循诚实报告优势策略的被试比例。我们将迭代机制的好处与它们在步骤之间提供给学生的前一个应用程序的结果的反馈联系起来。
We test experimentally the Gale-Shapley Deferred Acceptance (DA) mechanism versus two versions of the Iterative Deferred Acceptance Mechanism (IDAM), in which students make applications one at a time. A significantly higher proportion of stable outcomes is reached under IDAM than under DA. The difference can be explained by a higher proportion of subjects following an equilibrium truthful strategy under iterative mechanisms than the dominant strategy of truthful reporting under DA. We associate the benefits of iterative mechanisms with the feedback on the outcome of the previous application they provide to students between steps.
