Many economic transactions are prohibited—even in the absence of health or safety concerns or negative externalities—because of ethical concerns that cause these exchanges to be perceived as “repugnant” if conducted through a market. Establishing a system of payments for human organs is...

In many low- and middle-income countries blood donations per capita are substantially lower than in advanced economies. In these countries blood supply is mostly collected through donations by relatives and friends of individuals needing transfusions or to replace blood used in emergencies. The...

In many low- and middle-income countries blood donations per capita are substantially lower than in advanced economies. In these countries blood supply is mostly collected through directed donations from relatives and friends to individuals needing transfusions or to replace blood used in...

In an attempt to alleviate the shortfall in organs and bone marrow available for transplants, many U.S. states passed legislation providing leave to organ and bone marrow donors and/or tax benefits for live and deceased organ and bone marrow donations and to employers of donors. We exploit...

Many U.S. states have passed legislation providing leave to organ and bone marrow donors and/or tax benefits for live and deceased organ and bone marrow donations and to employers of donors. We exploit cross-state variation in the timing of such legislation to analyze its impact on organ...

We present evidence from nearly 14,000 American Red Cross blood drives and from a natural field experiment showing that economic incentives have a positive effect on blood donations without increasing the fraction of donors who are ineligible to donate. The effect increases with the incentive's...

We present evidence from a natural field experiment involving nearly 100,000 individuals on the effects of offering economic incentives for blood donations. Subjects who were offered economic rewards to donate blood were more likely to donate, and more so the higher the value of the rewards....

Using longitudinal data on the entire population of blood donors in an Italian town, we examine how donors respond to a nonlinear award scheme that rewards them with symbolic prizes (medals) when they reach certain donation quotas. Our results indicate that donors significantly increase the...

A number of experimental studies have documented that financial rewards discourage the performance of altruistic activities because they conflict with intrinsic altruistic motivations. However, it is unclear whether this is evidence of a generalized aversion to rewards or, rather, an aversion to...

Organizations and public agencies that promote pro-social activities constantly struggle to attract and encourage more contributions. In this article, we study the effects of an explicit reward in the context of blood donation. Specifically, we analyze the effects of a legislative provision that...
