Non-monetary rewards could be used to incentivise blood donation

Joan Costa-Font, Mireia Jofre-Bonet and Steven T Yen present research into incentivising blood donation. Classic research has found that monetary incentives to blood donors may crowd out blood supply as purely altruistic donors may feel less inclined to donate if a reward is involved. However it is argued that there would be no supply displacement of altruistic donors if non-monetary rewards were offered instead.
