摘要：We conduct a field experiment at a nonprofit organization's online store to study how demand changes when consumers' purchases can generate revenue for a charitable cause. When purchases can trigger a small donation by an outside anonymous group, consumers respond strongly and apparently without regard for the specific conditions that trigger the donation. Consumers respond similarly when the outside donation requires a personal donation which consumers generally decline. When the outside dona...

摘要：We study the effect of the social environment on the quantity and quality of voluntary labor contributions. By extending Benabou and Tirole's (2006) image signaling framework, we derive theoretical predictions on time volunteered given (1) the availability of excuses to stop volunteering and (2) the presence of an authority figure. We test these predictions in an experiment where laboratory subjects are directly involved in a local nonprofit operation. We find that in the absence of excuses to...

摘要：It is often difficult for donors to predict the value of charitable giving because they know little about their recipients. This concern is particularly acute when making contributions to organizations that serve heterogeneous populations. Prior research shows that donors are more generous if they know their assistance benefits a group they like. But we know little about the demand for such information. To start closing this gap, we study transfers of income to real-world poor people in dictat...

摘要：We present evidence from a natural field experiment designed to shed light on the efficacy of fundraising schemes in which donations are matched by a lead donor. In conjunction with the Bavarian State Opera House, we mailed 14,000 regular opera attendees. a letter describing a charitable fundraising project organized by the opera house. Recipients were randomly assigned to treatments designed to explore behavioral responses to linear matching schemes, as well as the mere existence of a substan...

摘要：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 chari...

摘要：To further our understanding of the economics of charity, we conducted a natural field experiment. Making use of two direct mail solicitations sent to nearly 20,000 prior donors to a charity, we tested the effectiveness of $1:$1 and $1:$3 matching grants on charitable giving. We find only weak evidence that either of the matches work; in fact, for the full sample, the match only increased giving after the match deadline expired. Yet, the aggregation masks important heterogeneities: those donor...

摘要：The public phase of a capital campaign is typically launched with the announcement of a large seed donation. Andreoni (1998) argues that such a fundraising strategy may be particularly effective when funds are being raised for projects that have fixed production costs. The reason is that when there are fixed costs of production simultaneous giving may result in both positive and zero provision equilibria. Thus absent announcements donors may get stuck in an equilibrium that fails to provide a ...

摘要：More than 200 donors participated in a framed field experiment which consisted of a series of decisions about how to divide a gift between a set of similar charities. Most subjects simultaneously gave to multiple charities with similar missions even when the social benefit of gifts to different charities were not equal, as proxied by the matching rates applied to subjects' gifts. Taking each subject's preferences over the set of charities as given, these choices resulted in substantial ineffic...

摘要：When the government gives a grant to a private charitable organization, do the donors to that organization give less? If they do, is it because the grants crowd out donors who feel they gave through taxes (classic crowd out), or is it because the grant crowds out the fundraising of the charities who, after getting the grant, reduce efforts of fundraising (fundraising crowd-out)? This is the first paper to separate these two effects. Using a panel of more than 8000 charities, we find that crowd...
