Abstract:Patients needing kidney transplants may have donors who cannot donate to them
because of blood or tissue incompatibility. Incompatible patient-donor pairs can
exchange donor kidneys with other pairs only when there is a "double coincidence
of wants." Developing infrastructure to perform three-way as well as two-way
exchanges will have a substantial effect on the number of transplants that can be
arranged. Larger than three-way exchanges have less impact on efficiency. In a
general model of type-compatible exchanges, the size of the largest exchanges
required to achieve efficiency equals the number of types. (JEL C78, I12)
