We model the determinants of donations made to UK overseas development charities using panel data on charities’ donation income covering a 25 year period. The paper starts by reviewing relevant theory and previous empirical work on donations to UK charities before outlining a framework in which donations are a function of fundraising, government grants, total household income, inequality in hou...

BACKGROUND Hepatitis E virus (HEV) Genotype 3 (G3) infection is a zoonosis that may be transmitted during the acute phase by transfusion. The aim of this study was to determine the incidence of HEV and seroprevalence among Irish blood donors. STUDY DESIGN AND METHODS Anonymized samples from 1076 donations collected in 2012 were tested for HEV immunoglobulin (Ig)G using the Wantai enzyme-linke...

An analysis of online charity donations reveals that, when males make large donations to attractive female fundraisers, other males respond in kind, providing field evidence for 'competitive altruism' in which helpful acts are used as a display to attract partners.

Rare hematopoietic stem cell populations are responsible for the transplantation engraftment process. Umbilical cord blood (UCB) is usually processed to total nucleated (TNC), but not mononuclear (MNC) fraction. TNC counts used determine UCB unit storage, release and correlation with time [1]. It has been mentioned in literature that there several factors affect harvesting of cells [2]. was set...

abstract background: identify talented people to donate predisposed a major role in supplying healthy blood. if the time interval between donations decrease, the chance that voluntary of blood donation be a regular donor increase. the aim of this study was to determine factors affecting the interval between blood donations in a sample of first-time blood donors. methods: data of a cross-section...

Charities frequently rely on professional solicitors whose commissions exceed half of total donations. To understand this practice, we propose a principal-agent model in which the charity optimally offers a higher commission to a more “efficient” solicitor, raising the price of giving significantly. Outsourcing is, therefore, profitable for the charity only if giving is very price-inelastic. Th...

Stem cell transplants save lives of many patients with blood diseases. Donation is painful, but rarely has lasting adverse effects. Patients can accept transplants only from donors with compatible immune systems. Those lacking a sibling match must seek donations from the general population. The probability that two unrelated persons are compatible is less than 1/10,000. Health authorities maint...

In this paper, we employ a unique new data set (the Philanthropy Panel Study (PPS), a module within the Panel Study of Income Dynamics (PSID)) to test whether the propensity to donate out of inherited wealth is equal to the propensities to donate out of other wealth, earned income, and transfer payments. We find that the elasticity of giving from non-inherited wealth is much greater than from i...

The empirical literature on the determinants of charities’ donation income, distinguishing the charitable cause, is small. We consider the case of development charities specifically. Using a panel covering a quarter of a century, we observe a strong fundraising effect and a unitary household income elasticity. We find evidence that the conventionally identified ‘price’effectmay simply be the pr...
