Robust participation incentives in dynamic kidney exchange
研究了动态肾脏交换项目中，相容患者-捐赠者对的参与激励问题，通过考虑结果分布的不确定性，提出了一个稳健的合同设计，该合同包含最低质量保证和无限期停留，能够吸引参与者并实现社会最优。
Robustness to plausible distributions of outcomes helps rationalize straightforward participation incentives for Compatible patient–donor Pairs in dynamic kidney exchange programs. The CP faces ambiguity on the distribution of outcomes in every matching round and evaluates participation conditions -minimum guaranteed quality and committed number of rounds before fallback- according to every plausible distribution. When the decay of the donor’s organ quality between rounds is negligible, the ex-ante and ex-post individually rational socially optimal contract involves a minimum guarantee exactly equal to the fallback option and an unlimited, self-enforced stay at the pool. The model also easily explains that no contract can attract a CP with sufficiently high reservation value to the exchange pool.
