A Simulation Model for the Multi-Period Kidney Exchange Incentivization Problem

摘要

Kidney exchanges provide an opportunity for individuals who need a new kidney to effectively trade a donor’s incompatible kidney for a compatible one. We present a mechanism for fully dynamic kidney exchanges that incentivizes transplant centers to truthfully participate in global matchings through a credit-based weighting scheme. Our mechanism incorporates both cycles and altruistically initiated chains while allowing patients to remain in the system for multiple time periods. Using simulation, we demonstrate that this credit-based matching mechanism is strategy-proof, individually rational, and efficient for all transplant centers under the assumption that all offered matches are accepted.
