A Comparison of Multiple-Unit All-Pay and Winner-Pay Auctions under Incomplete Information by Yasar Barut, Dan Kovenock, and Charles Noussair This paper examines the properties of independent-private-value all-pay and winner-pay auctions when there are multiple units sold. We study bidding behavior, efficiency and revenue in a set of nine experimental sessions, each with six bidders. All-pay auctions were played in six of the sessions, three sessions with four units and three sessions with two units auctioned. A four-unit winner-pay auction was played in three of the sessions. Our data show that the all-pay auction and the winner-pay auction are empirically revenue equivalent and yield higher revenue than the risk neutral Bayesian equilibrium. Revenue is higher in the allpay auction when K=2 than when K=4, despite the fact that Bayesian equilibrium revenues are identical for the two cases. Our evidence also suggests that the winner-pay auction is more likely than the all-pay auction to lead to a Pareto-efficient allocation.

Behavior in all-pay auctions with incomplete information
This paper analyzes the behavior of single-unit all-pay auctions within the independent private values environment in the laboratory. We study revenue, individual bidding behavior, and efficiency, in relation to theoretical benchmarks and to a similar study of winner-pay first-price sealed-bid auctions. We conclude that the all-pay auction yields significantly higher revenue than both the riskn...
متن کاملMunich Personal RePEc Archive Charity Auctions for the Happy Few
Recent literature has shown that all-pay auctions raise more money for charity than either winner-pay auctions or lotteries. We demonstrate that first-price and second-price winnerpay auctions have a better revenue performance than first-price and second-price all-pay auctions when bidders are sufficiently asymmetric. Lotteries can also provide higher revenue than all-pay auctions. To prove thi...
متن کاملHow (Not) to Raise Money
We show that standard winner-pay auctions are inept fund-raising mechanisms because of the positive externality bidders forgo if they top another’s high bid. Revenues are suppressed as a result and remain finite even when bidders value a dollar donated the same as a dollar kept. This problem does not occur in lotteries and all-pay auctions, where bidders pay irrespective of whether they win. We...
متن کاملEvolutionary dynamics of biological auctions.
Many scenarios in the living world, where individual organisms compete for winning positions (or resources), have properties of auctions. Here we study the evolution of bids in biological auctions. For each auction, n individuals are drawn at random from a population of size N. Each individual makes a bid which entails a cost. The winner obtains a benefit of a certain value. Costs and benefits ...
متن کاملCross and Double Cross: Comparative Statics in First Price and All Pay Auctions
This paper analyses comparative statics for first price auctions and all pay auctions with independent private values. In all pay auctions, bidders with low values will respond to a stochastically higher (in the sense of likelihood ratio dominance) distribution of types by playing less aggressively while high value bidders bid more. In the first price auction, a similar change results in all ty...
