Market design and matching have been especially important for markets in which the use of money is viewed as repugnant or distasteful. This article employs the example of kidney exchange, with a particular focus on a new form, global kidney exchange (GKE), to highlight the manner by which repugnance and the law limit exchange and create scarcity. Yet it also opens the door to innovation that, at each stage of market development, prompts new repugnance concerns and initiates a renegotiation of legal rules, social norms, and institutional barriers.
