Over at MR, Alex Tabarrok wrote a little while ago about the earlier work of Bob and his colleagues on blood donation:
...The decision to donate blood involves complex motivations including altruism, civic duty and moral responsibility. As a result, we agree with Buttonwood that in theory incentives could reduce the supply of blood. In fact, this claim is often advanced in the popular press as well as in academic publications, and as a consequence, more and more often it is taken for granted.But what is the effect of incentives when studied in the real world with real donors andactual blood donations?We are unaware of a single study of real blood donations that shows that offering an incentive reduces the overall quantity or quality of blood donations. From our two studies, both in the United States covering several hundred thousand people, and studies by Goette and Stutzer (Switzerland) and Lacetera and Macis (Italy), a total of 17 distinct incentive items have been studied for the effects on actual blood donations. Incentives have included both small items and gift cards as well as larger items such as jackets and a paid-day off of work. In 16 of the 17 items examined, blood donations significantly increased (and there was no effect for the one other item), and in 16 of the 17 items studied no significant increase in deferrals or disqualifications were found. No study has ever looked at paying cash for actual blood donations, but several of the 17 items in the above studies involve gift cards with clear monetary value.
