We introduce a new criterion to compare the properties of mechanisms when the solution concept used induces multiple solutions. Our criterion generalizes previous approaches in the literature. We use our criterion to compare the stability of constrained versions of the Boston (BOS) and deferred...

We compare the manipulability of school choice mechanisms based on the occurrence of dominant strategies. We characterize dominant strategies in the constrained versions of the deferred acceptance (DA) and Boston (BOS) mechanisms. We leverage our characterizations to show that dominant...

School choice mechanisms are typically constrained, with students allowed to report preferences on a limited number of schools only Under constraints, the deferred acceptance mechanism (DA) is manipulable and it is unclear how students should play in DA. In order to provide advice to...
