This study analyzed the viability of financing a voucher program for cocaine addicts in Spain through public and private donations. Of the 136 companies contacted, 52 (38%) provided donations. The difference between the benefits (15,670 Euro/ $20,371) and the costs (3734 Euro/ $4854) was 11,936 Euro/ $15,517.

The reported IgG seroprevalence against hepatitis E virus (HEV) in German blood donations is 6.8%, and HEV RNA detected in 0.08%, but documented evidence for HEV transmission is lacking. We identified two donations from a single donor containing 120 IU HEV RNA/mL plasma and 490 IU/mL. An infectious dose of 7,056 IU HEV RNA was transmitted via apheresis platelets to an immunosuppressed patient w...
We report on the results of laboratory experiments of voluntary giving with suggested donations. Asking subjects to give the socially optimal amount reduces giving compared to no suggestion. Asking subjects not to give also depresses giving. However, moderate suggested donations produce modest positive e¤ects. We o¤er a model using the fairness equilibrium framework of Rabin (1993) that is capa...

Voluntary blood donations have to be made a part of a healthy lifestyle.

NGOs are widely perceived to raise their flag in humanitarian hot-spots with strong media presence in order to attract higher private donations. We assess this hypothesis by comparing the changes in donations between US-based NGOs with and without activities in the four countries most affected by the tsunami in the Indian Ocean in 2004. Performing a difference-in-difference-in-differences (DDD)...
This paper provides an econometric analysis of the relationship between live and deceased (cadaveric) kidney donations for the United States for the period 1992:IV through 2006:II. We find strong evidence for deceased donor kidneys "crowding out" living donations, potentially undermining conventional efforts to reduce the shortage. We also find evidence for the "dirty altruism" hypothesis of Os...
Alanine aminotransferase (ALT) levels were determined in 8,420 plasmapheresis donations obtained from 431 donors over a period of 18 months. Using sex-differentiated normal ranges 2.5% of donations but 23% of donors exhibited elevated ALT levels on at least 1 occasion. Amongst the donors with elevated ALT this was only seen on 1 occasion in one third, while a quarter had elevations in consecuti...
