Multiperiod matching

February 5, 2019

Sangram Kadam and co-author Maciej H. Kotowski examine a dynamic, two‐sided, one‐to‐one matching market where agents on both sides interact over a period of time. The authors define and identify sufficient conditions for the existence of a dynamically stable matching, which may require revisions to initial assignments. A generalization of the deferred acceptance algorithm can identify dynamically stable outcomes in a large class of economies, including cases with intertemporal preference complementarities. They relate their analysis to market unraveling and to common market design applications, including the medical residency match.
