We introduce a new matching model to mimic two-sided exchange programs such as tuition and worker exchange, in which each firm has to avoid being a net-exporter of workers. These exchanges use decentralized markets, making it difficult to achieve a balance between exports and imports. We show...

Yu and Zhang (2020) propose a job rotation model to study rotation schemes thatwidely exist in real life. In the model agents' rights to consume own endowmentsare restricted, but their rights to trade endowments are unrestricted. This poses aninteresting contrast with the housing market model of...

In discrete exchange economies with possibly redundant and joint ownership, we propose new core notions in the conventional flavor by regarding endowments as rights to consume or trade with others. Our key idea is to identify self-enforcing coalitions and to redistribute their redundant property...

Mechanisms that rely on course bidding are widely used at Business Schools in order to allocate seats at oversubscribed courses. Bids play two key roles under these mechanisms to infer student preferences and to determine who have bigger claims on course seats. We show that these two roles may...

This paper studies the incentive compatibility of solutions to generalized indivisible good allocation problems introduced by Sonmez (1999), which contain the well-known marriage problems (Gale and Shapley, 1962) and the housing markets (Shapley and Scarf, 1974) as special cases. In particular,...

Organizations (especially firms) often rotate employees' jobs from period to period. We propose a market design approach to organize job rotation in any given period. In our model each employee has occupied a position. Rotation requires that the occupier of a position must leave if any other...

We study the object allocation problem and present two new characterizations of ordinal efficiency in terms of supports of random assignments. Our main characterization provides a link between ex-post and ordinal efficiency

We introduce a new matching model to mimic two-sided exchange programs such as tuition and worker exchange, in which each firm has to avoid being a net-exporter of workers. These exchanges use decentralized markets, making it difficult to achieve a balance between exports and imports. We show...

In a matching problem between students and schools, a mechanism is said to be robustly stable if it is stable, strategy-proof, and immune to a combined manipulation, where a student first misreports her preferences and then blocks the matching that is produced by the mechanism. We find that even...
