The giving type: Identifying donors Academic Article uri icon


  • One commonly used strategy in charitable fundraising is sharing names and contact information of donors between organizations, even those whose missions are unrelated. The efficacy of this practice hinges on the existence of "giving types," that is, a positive correlation at the individual level between giving to one organization and to another. We run an experiment using a non-student sample (an artifactual field experiment) in which participants have the opportunity to donate to multiple charitable organizations. We examine the relationship between giving to one organization and giving to another. Our results support the existence of a giving type; a factor analysis demonstrates that giving decisions are driven by a single (unique) factor, and individuals who give to one organization, give significantly more to other organizations than do non-donors. Our results have important implications for the economics of charity and for fundraising practice. 2010.
