Blood Allocation with Replacement Donors: A Theory of Multi-unit Exchange with Compatibility-based Preferences

Research Seminars

In 56 developing and developed countries, blood component donations by volunteer non-remunerated donors can only meet less than 50% of the demand. In these countries, blood banks rely on replacement donor programs that provide blood to patients in return for donations made by their relatives or friends. These programs appear to be disorganized, non-transparent, and inefficient. The authors introduce the design of replacement donor programs and blood allocation schemes as a new application of market design. They introduce optimal blood allocation mechanismsthat accommodate fairness, efficiency, and other allocation objectives, together with endogenous exchange rates between received and donated blood units beyond the classical one-for-one exchange. Additionally, the mechanisms provide correct incentives for the patients to bring forward as many replacement donors as possible. This framework and the mechanism class also apply to general applications of multi-unit exchange of indivisible goods with compatibility-based preferences beyond blood allocation with different information problems.
