The growth of kidney exchange presents new challenges for the design of kidney exchange clearinghouses. The players now include directors of transplant centers, who see sets of patientdonor pairs, and can choose to reveal only difficult to match pairs to the clearinghouse, while withholding easy to match pairs to transplant locally. This reduces the number of transplants. We discuss how the inc...

Literature shows that blood type O patients are less likely to be selected for transplantation within a living exchange donation program. 'Altruistically unbalanced donation' could help these blood type O patients: one donor-recipient pair is incompatible (e.g. A-donor ...
