Ágnes CSEH: Organizing Time Banks: Lessons from Matching Markets
(with T. Andersson, L. Ehlers, and A. Erlanson)
A time bank is a group of people that set up a common platform to trade services among themselves. There are several well-known problems associated with this type of time banking, e.g., high overhead costs and difficulties to identify feasible trades. This works constructs a nonmanipulable mechanism that selects an individually rational and time-balanced allocation which maximizes exchanges among the members of the time bank (and those allocations are efficient). The mechanism works on a domain of preferences where agents classify services as unacceptable and acceptable (and for those services agents have specific upper quotas representing their maximum needs).
