Research in this theme covers topics such as dynamic matching models inspired by the assignment of social housing, high school teachers and administrative positions; assignment methods based on the accumulation of seniority points, contrasting different assignment methods and using queuing theory to construct optimal mechanisms; assignment of temporary property rights (such as hotel rooms and rental cars)…

Research in this theme covers topics such as the use of networks to elicit information about agents’ characteristics, either by constructing mechanisms where agents report on their neighbors or mechanisms where agents reveal their position in a network; “network interdiction” pitting an attacker (whose objective is to capture nodes) against a defender (who protects nodes and designs the network)…
