COVID-19 has revealed limitations of existing mechanisms for rationing medical resources
under emergency scenarios. Many argue that these mechanisms abandon various ethical …

Matching problems under preferences have been studied widely in mathematics, computer
science and economics, starting with the seminal paper by Gale and Shapley (1962). A …

In an earlier work (Kamada and Kojima 2015), we introduced “matching with constraints,” a
two-sided matching problem in which the market is subject to feasibility constraints. That …

Organizations often require agents' private information to achieve critical goals such as
efficiency or revenue maximization, but frequently it is not in the agents' best interest to …

We consider two-sided matching problems where agents on one side of the market
(hospitals) are required to satisfy certain distributional constraints. We show that when the …

Many real matching markets are subject to distributional constraints. To guide market
designers faced with constraints, we propose new stability concepts. A matching is strongly …

This paper studies a general model of matching with constraints. Observing that a stable
matching typically does not exist, we focus on feasible, individually rational, and fair …

In many-to-one matching with contracts, agents on one side of the market, eg, workers, can
fulfill at most one contract, while agents on the other side of the market, eg, firms, may desire …

Abstract The H-1B Visa Reform Act of 2004 dictates an annual allocation of 85,000 visas
with 20,000 reserved for advanced-degree applicants. We represent the main requirements …

In the past few years, several new matching models have been proposed and studied that
take into account complex distributional constraints. Relevant lines of work include (1) …
