Data from a recent ?eld experiment suggests that differences in participation rates are responsible for much of the variations in revenues across formats in charity auctions. We provide a theoretical framework for the analysis of this, and other related, results. The model illustrates the limits...

Auctions are a popular way to raise money for charities, but relatively little is known, either theoretically or empirically, about the properties of charity auctions. The small theoretical literature suggests that the all-pay auction should garner more money than winner-pay auctions. We conduct...

Despite its popularity as a fundraiser for charities, very little research has been done on the bidding and revenue properties of the silent auction. This paper examines the consequences of two behaviors common in silent auctions, jump-bidding and sniping, in laboratory experiments with...

Donations in-kind can be a mixed blessing for charities, who are often more adept at solicitation than resale. Many organizations rely on raffles to turn donations into cash, but auctions are also common. Theory predicts that all-pay mechanisms should produce more revenue than winner-pay...

Auctions are a popular way to raise money for charities, but relatively little is known, either theoretically or empirically, about the properties of charity auctions. We conduct field experiments to see which sealed bid format, first price, second price or all-pay, raises the most money. Our...

In many environments, tournaments can elicit more effort from workers, except perhaps when workers can sabotage each other. Because it is hard to separate effort, ability and output in many real workplace settings, the empirical evidence on the incentive effect of tournaments is thin. There is...

We define social reciprocity as the act of demonstrating one's disapproval, at some personal cost, for the violation of widely-held norms (e.g., don't free ride). Social reciprocity differs from standard notions of reciprocity because social reciprocators intervene whenever a norm is violated...
