| Research Abstract |
We consider problems of matching mechanism design from the viewpoint of stability and strategy-proofness. The first research studies one-to-one matching problems and analyze conditions on preference domains that admit the existence of stable and strategy-proof rules. We introduce the notion of the no-detour condition (NDC), and show that under this condition, there is a stable and group strategy-proof rule. We also show that under the assumption that the preference domain for the agents on one side is unrestricted, if there is a stable and strategy-proof rule, then the NDC is satisfied. The second research studies many-to-one matching problems with responsive preferences where unacceptable agents may exist on both sides and explore conditions for the core to be a singleton. We investigate two types of necessary and sufficient conditions for that. One is a condition on the preferences of the colleges, called acyclicity and the other is a condition on the capacities of the colleges.
