In a door-to-door fundraising field experiment, we study the impact of fundraising mechanisms on charitable giving. We approached about 4500 households, each participating in either an all-pay auction, a lottery, a non-anonymous voluntary contribution mechanism (VCM), or an anonymous VCM. In...

This paper investigates the determinants of generosity in an experiment on charity to real-life welfare recipients. It tests the effects of various measures of unconditional altruism and conditional or reciprocal altruism. The results show strong support for conditional or reciprocal altruism....

In the year 2007 It was held the research project called “Measuring Trust, Trustworthiness and Pro-Sociality in Six Latin American Cities”: Bogotá, D.C, Buenos Aires, Caracas, Lima, Montevideo and San José de Costa Rica. The purpose of this study was to analyze the interaction between...

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...

We document the hidden costs of a popular nudge and show how these costs distort policy making when neglected. In a field experiment with a charity, we find reminders increasing intended behavior (donations), but also increasing avoidance behavior (unsubscriptions from the mailing list). We...

A popular fundraising tool is donation matching, where every dollar is matched by a third party. But field experiments find that matching does not always increase donations. This may occur because individuals believe that peer donors will exhaust the matching funds, so their donation is not...

Existing sociological research on support for anti-poverty programs largely focuses on broad categories of welfare or assistance to the poor rather than particular types of transfers. Using an experimental survey design and mixed methods research, we examine whether support for anti-poverty...

In an experimental setup we investigate the effect of providing a list of default charities on donation decisions. In the treatment group, subjects can either specify a charity of their choice, or select one from a list of five well-known charities; in the control group we do not provide the...

Theory commonly posits agents who care both for the level of provision of a public good and the extent to which they personally contribute to the cause. Simply put, agents feel some "warm glow" from the donations they make. I discuss a fundraiser devised to exogenously vary the incentive to give...

The declining use of cash in society urges charities to experiment with digital payment instruments in their off-line fund raising activities. Cash and card payments differ in that the latter do not require individuals to donate at the time of the ask, disconnecting the decision to give from the...
