Altruistic Kidney Exchange Abstract: The recent literature on kidney exchange mostly considers exchange between incompatible donor-patient pairs where a donor cannot medically donate a kidney to her own patient even she can donate to the patient of the other pair. It has been shown that major efficiency gains are obtained if compatible pairs can be included in exchange. We consider a model with both incompatible and compatible pairs, and extend some of the results in the literature. One practically important extension is that the number of patients who receive a transplant is the same at each Pareto efficient matching. We also extend the well-known Gallai -Edmonds Decomposition Lemma to present model. This is joint work with Utku Unver.
