It has been previously shown that for sufficiently large pools of patient-donor pairs, (almost) efficient kidney exchange can be achieved by using at most 3-way cycles, i.e. by using cycles among no more than 3 patient-donor pairs. However, as kidney exchange has grown in practice, cycles among...

Waitlists are often used to ration scarce resources, but the trade-offs in designing these mechanisms depend on agents preferences. We study equilibrium allocations under alternative designs for the deceased donor kidney waitlist. We model the decision to accept an organ or wait for a preferable...

In this article, we propose a novel form of kidney swap, which we label “Reverse Transplant Tourism.” This proposal has the potential to increase the number of successful transplants in the US at a time of great need, while reducing costs. It also will provide benefits to impoverished...

This article distinguishes criminal, legal, and ethical transplantation as three distinct concepts, with the goal of building a conceptual framework to enable innovation. We strongly believe that international efforts should concentrate on increasing the availability of ethical high-quality...
