The Price of Warm Glow This paper presents a model and experimental evidence to explain the “volunteering puzzle" where agents prefer volunteering time to donating money when monetary donations are, ceteris paribus, more efficient for providing resources to charity. In the model agents receive heterogeneous utility from pure and impure altruism (Andreoni 1989) that permits warm glow to vary bet...

Approximately 1 in 20 unrelated donors are asked to make a second donation of hematopoietic progenitor cells, the majority for the same patient. Anthony Nolan undertook a study of subsequent hematopoietic progenitor cell donations made by its donors from 2005 to 2011, with the aims of predicting those donors more likely to be called for a second donation, assessing rates of serious adverse reac...

An "in-house" RT-PCR method was developed that allows the simultaneous detection of the RNA of the Hepatitis C Virus (HCV) and an artificial RNA employed as an external control. Samples were analyzed in pools of 6-12 donations, each donation included in two pools, one horizontal and one vertical, permitting the immediate identification of a reactive donation, obviating the need for pool dismemb...

In living donor kidney transplantation there are disproportionately more female-to-male donations and fewer male-to-female donations. Given the rapid increase in living donor transplantation, we studied gender demographics and outcomes of these transplants. We analyzed living donor kidney transplants in the Scientific Registry of Transplant Recipients (SRTR) database between 1990 and 1999. Ther...

BACKGROUND Hepatitis E virus (HEV) infection has become relevant to blood transfusion practice because isolated cases of blood transmission have been reported and because HEV has been found to cause chronic infection and severe liver disease in immunocompromised patients. STUDY DESIGN AND METHODS We tested for immunoglobulin (Ig)G and IgM antibodies to the HEV and for HEV RNA in 1939 unselect...

BACKGROUND Transfusion Transmissible Infections (TTIs) such as Human Immunodeficiency Virus (HIV), syphilis, hepatitis B virus (HBV) and hepatitis C virus (HCV) are infections which are common in some communities in Southern Africa. It is important to screen blood donations for these infections. METHODS This is a retrospective study which involved reviewing of previous blood donation records ...

A total of 70 224 blood donations were tested at three Scottish blood transfusion centres for hepatitis B surface antigen /HBsAg) by an economical haemagglutination-inhibition method (E.H.A.I.) and the results compared with those of counterelectrophoresis (C.E.P.). A further 4086 donations were tested using the Wellcome turkey cell haemagglutination test, C.E.P., and E.H.A.I.E.H.A.I. was also c...

This article reports the results of an exploratory study on corporate philanthropy using a sample of 206 Canadian companies. The results show that a corporation is more likely to have a professional donation program if it is large, privately owned, and the manager of the corporation acts as a volunteer fundraiser for a charitable organization. The second part of the study finds that the level o...

An individual should be indifferent between a rebate subsidy of rate sr and a matching subsidy of rate sm = sr/(1 sr), and the total amount received by the charity should be the same regardless of subsidy type. Recent laboratory and field experiments contradict these straightforward predictions of standard economic theory: subjects consistently make decisions that result in larger amounts going...
