BACKGROUND Although blood donations may reduce body iron stores, to date, prospective data on frequent blood donation and colorectal cancer risk are limited. METHODOLOGY/PRINCIPAL FINDINGS We tested whether frequent blood donation is associated with a lower risk of colorectal cancer in the Health Professionals Follow-up Study. We prospectively followed 35,121 men who provide the information o...

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,...

The prevalence of HBV DNA among seronegative blood donations in China has not been studied extensively on a nationwide scale. The aim of this study was to analyse the prevalence, trend, distributions, and serological characteristics of HBV DNA positive/seronegative blood donations. We collected HBV test data from all blood banks of China from 2010 to 2015 and performed supplemental serological ...

A common form of Corporate Social Responsibility (CSR) by firms is to agree to donate a fixed portion of private good revenues to a charitable cause. In this paper we explore a new rationale for such CSR. We argue that linking private good purchase with charitable donations allows the firm to price discriminate between altruistic consumers who wish to make charitable donations out of their inco...

BACKGROUND Human cadavers are crucial to numerous aspects of health care, including initial and continuing training of medical doctors and advancement of medical research. Concerns have periodically been raised about the limited number of whole body donations. Little is known, however, about a unique form of donation, namely co-donations or instances when married individuals decide to register ...

OBJECTIVE to assess drug donations in terms of their adherence to the drug donation guidelines put forth by the World Health Organization (WHO). METHODS in 2009 we searched the academic and lay literature - journal articles, media articles and industry and donor web sites - to identify reports about drug donations made from 2000 to 2008. Publications focusing on molecular mechanisms of drug a...

Prior research indicates that donations respond to price and income effects as well as to alternative sources of nonprofit financing. Using a database of confidential nonprofit tax returns, we examine the effects of nonprofits’ taxable activities on the supply of donations. We find that each additional dollar of taxable revenues crowds-out approximately $0.55 of donations to arts, culture, and ...

We study how competition among charities affects individuals’ giving behavior. We characterize a situation where a higher rebate subsidy shifts donations from one charity to another and increases total donations. We conduct two experiments: (i) individualized charitable giving where free riding incentives are shut down; and (ii) multi-donor charitable giving. We derive the demand for giving at ...

We experimentally study the transparency effect of alternative campaign finance systems on donations, election outcomes, policy choices, and welfare. Three alternatives are considered: one where donors’ preferences and donations are unobserved by the candidate and public; one where they are observed by the candidate but not the public; and one where they are observed by all. We label them full ...
