Blood donations by volunteer non-remunerated donors can only meet less than 50% of demand in 56 countries where blood banks had to adopt replacement donor programs to provide blood to patients in return for donations made by their donors. These programs are inefficient, as they limit the direct exchange of donors among patients. We introduce a novel framework and propose a general mechanism class accommodating efficiency objectives that embed current practices and other plausible fairness criteria. These mechanisms are incentive-compatible for patients to truthfully reveal their utility functions and replacement donors. Our framework also applies to other multi-unit exchange problems.
