Pairwise kidney exchange: Comment
نویسنده
چکیده
In their recent paper, Roth et al. [Pairwise kidney exchange, J. Econ. Theory 125 (2005) 151–188] consider pairwise kidney exchanges, and show within this subset of feasible exchanges that a priority mechanism is strategy-proof. We show that this result can be broadened to allow much more general mechanisms and restrictions on the feasible set of allocations, including allowing three-way exchanges, regional specifications, and others. The key requirement is that the choice mechanism be consistent, i.e., if an allocation is chosen from some set of feasible allocations, it is also chosen from any subset of that set. © 2005 Elsevier Inc.

Low-Risk Mechanisms for the Kidney Exchange Game
In this paper we consider the pairwise kidney exchange game. This game naturally appears in situations that some service providers benefit from pairwise allocations on a network, such as the kidney exchanges between hospitals. Ashlagi et al. [1] present a 2-approximation randomized truthful mechanism for this problem. This is the best known result in this setting with multiple players. However,...
متن کاملAge-based preferences in paired kidney exchange
We consider a model of Paired Kidney Exchange (PKE) with feasibility con-straints on the number of patient-donor pairs involved in exchanges. Patients’preferences are restricted so that patients prefer kidneys from compatible youngerdonors to kidneys from older donors. In this framework, patients with compati-ble donors may enroll on PKE programs to receive an organ with higher ...
متن کاملPairwise kidney exchange
In connection with an earlier paper on the exchange of live donor kidneys (Roth, Sönmez, and Ünver 2004) the authors entered into discussions with New England transplant surgeons and their colleagues in the transplant community, aimed at implementing a Kidney Exchange program. In the course of those discussions it became clear that a likely rst step will be to implement pairwise exchanges, bet...
متن کاملGovernance in Health – The Need for Exchange and Evidence; Comment on “Governance, Government, and the Search for New Provider Models”
Governance in health is cited as one of the key factors in balancing the concerns of the government and public sector with the interests of civil society/private players, but often remains poorly described and operationalized. Richard Saltman and Antonio Duran look at two aspects in the search for new provider models in a context of health markets signalling liberalisation: (i) the role of the ...
متن کاملEgalitarian pairwise kidney exchange: fast algorithms vialinear programming and parametric flow
We revisit the pairwise kidney exchange problem established by Roth Sonmez and Unver [23]. Our goal, explained in terms of graph theory, is to find a maximum fractional matching on an undirected graph, that Lorenz-dominates any other fractional matching. The Lorenz-dominant fractional matching, which can be implemented as a lottery of integral matchings, is in some sense the fairest allocation ...
