报告摘要：

We study the model of job rotation problems proposed by Yu and Zhang (2020), in which there may exist vacant positions or new employees, moreover, each position has been occupied by at most one agent and each agent occupies at most one position. In each occupied position, the occupant has the lowest priority while all other agents have the equal priority. This priority structure is the “opposite” to that of the classic model of house allocation with existing tenants. In this paper, we propose two intuitive and constrained efficient mechanisms in this model, one is the modified Top Trading Cycle (TTC) mechanism, the other is the modified You Request My House-I Get Your Turn (YRMH-IGYT) mechanism. Only in the case that there is no vacant position or new employee, these two mechanisms are both weakly group strategy-proof, moreover, they both coincide with the Backward-induction TTC mechanism proposed by Yu and Zhang (2020).
