There has been little systematic study of the mechanisms typically used to raise money for charity. One of the most common is the simple raffle in which participants purchase chances to win a prize at a constant price. We conduct a field experiment randomly assigning participants to four raffle...

Early studies often found that offering economic incentives for undertaking prosocial and intrinsically motivated activities can crowd out motivation to perform these activities. More recent work highlights nuanced and important features related to whether crowding out (or substitution) is...

We examine optimal incentives for charitable giving with a large-scale field experiment involving 26 charities and over 112,000 unique individuals. The price of giving is varied by offering a fixed match if the donation meets a threshold amount (e.g. "give at least $25 and the charity receives a...

This paper theoretically explores the voluntary provision of a public good in a finitely repeated setting. Agents' utility is the sum of their monetary earnings and a non-material psychological component that can be interpreted as a taste for efficiency and/or fairness. An arbitrarily small...

An extensive literature on reputation signaling in prosocial settings has focused on an intrinsic desire for positive reputation. In our paper, we provide experimental evidence that some individuals are averse to both positive and negative reputation, and will, therefore, respond to visibility...

We present the first causal evidence on the persistent impact of enduring competition on prosociality. Inspired by the literature on tournaments within firms, which shows that competitive compensation schemes reduce cooperation in the short-run, we explore if enduring exposure to a competitive...

This paper examines image motivationthe desire to be liked and well-regarded by others as a driver in prosocial behavior (doing good), and asks whether extrinsic monetary incentives (doing well) have a detrimental effect on prosocial behavior due to crowding out of image motivation. By...
