We test how donors respond to new information about a charity's effectiveness. Freedom from Hunger implemented a test of its direct marketing solicitations, varying letters by whether they include a discussion of their program's impact as measured by scientific research. The base script, used...

We develop a dynamic game to explore the interaction between regulation and private policies, such as self-regulation by firms and activism. Without a public regulator, the possibility of self-regulation is bad for the firm, but good for activists who are willing to maintain a costly boycott to...

We conducted a natural field experiment to explore the effect of price changes on charitable contributions. To operationalize our tests, we examine whether an offer to match contributions to a non-profit organization changes the likelihood and amount that an individual donates. Direct mail...

If being asked to give to charity stimulates an emotional response, like empathy, that makes giving difficult to resist, a natural self-control mechanism might be to avoid being asked in the first place. We replicate a result from a field experiment that points to the role of empathy in giving....

A general finding in the empirical literature on charitable giving is that among older individuals, both the probability of giving and the conditional amount of donations decrease with age, ceteris paribus. In this paper, we use data on giving by alumni at an anonymous university to investigate...

A long literature has examined the effects of the price of giving - that is, the amount an in-dividual must give for one dollar to accrue to the charitable activity itself - on donative behavior. We use data from DonorsChoose.org, an online platform linking teachers with prospective donors, that...

We conduct a laboratory experiment to test if there are differences in behavior when subjects can donate either time or money to charity. Our subjects perform an effort task to earn money. In one condition they can have their efforts accrue to a charity instead of themselves. In other conditions...

A large economics literature seeks to understand the reasons why individuals make charitable contributions. Fundamental features of most models of charitable giving are the inclusion of externalities induced by other agents and the Lancasterian characteristics approach to specifying utility...

We develop a theory of prosocial behavior that combines heterogeneity in individual altruism and greed with concerns for social reputation or self-respect. Rewards or punishments (whether material or image-related) create doubt about the true motive for which good deeds are performed and this...

We present evidence from a natural field experiment involving nearly 100,000 individuals on the effects of offering economic incentives for blood donations. Subjects who were offered economic rewards to donate blood were more likely to donate, and more so the higher the value of the rewards....
