Blood donations and incentives: evidence from a field experiment
There is a longstanding concern that material incentives might undermine prosocial motivation, leading to a decrease in blood donations rather than an increase. This paper provides an empirical test of how material incentives affect blood donations in a large-scale field experiment spanning three months and involving more than 10,000 previous donors. We examine two types of incentive: a lottery ticket and a free cholesterol test. Lottery tickets significantly increase donations, in particular among less motivated donors. The cholesterol test leads to no discernable impact on usable blood ...

The hypothesis is tested in a large-scale field experiment on blood donations. We find that this ?active-decision? intervention substantially increases the actual donation behavior of people who had not fully ...
