【 The Digital Star Seminar Series No.19 】The Core in Housing Markets with Indifferent Preferences
Date: 13 May 2022 (Fri)
Time: 3:00pm - 4:30pm (Hong Kong Time, UTC+8)
Platform: Tencent Meeting (ID 356-473-582)
Host: Prof. Miaojun Wang (School of Economics, Zhejiang University)
Presenter: Prof. Jun Zhang (The Nanjing Audit University)
In the housing market model, Shapley & Scarf (1974) and Roth & Postlewaite (1977) show that when agents’ preferences are not strict, the strong core may be empty, while the nonempty weak core may be inefficient and larger than the set of intuitively reasonable allocations. We solve this problem by proposing two new core concepts through rectifying behavioral assumptions on the participation of unaffected agents in blocking coalitions. The two cores are nonempty, efficient, and coincide with the strong core whenever the strong core is nonempty. We also generalize the concept of competitive allocations, and show that there exist competitive allocations in the two cores.
