An allocation rule that prioritizes registered donors increases the willingness to register for organ donation, as laboratory experiments show. In public opinion, however, this priority rule faces repugnance. We explore the discrepancy by implementing a vote on the rule in a donation experiment,...

Recent laboratory experiments have demonstrated that prioritizing registered donors on the waiting list impressively increases the willingness to register as an organ donor. In these experiments, registered organ recipients are prioritized regardless of howlong they have been on thewaiting list....

Giving registered organ donors priority on organ waiting list can substantially increase the number of donors and save lifes. Evidence for these effects comes from recent experiments that implemented such priority rules in abstract laboratory environments. In these experiments, participants who...

We present evidence from a natural field experiment designed to shed light on the efficacy of fundraising schemes in which donations are matched by a lead donor. In conjunction with the Bavarian State Opera House, we mailed 14,000 regular opera attendees a letter describing a charitable...

Is there a way of matching donations that avoids crowding out? And, more generally, what is the best way to utilize a bigger lead gift for raising smaller contribu-tions in a fundraising campaign? To answer these questions, we present a novel matching method, some simple theoretical...
