Different pricing rules in multiunit auctions provide different incentives for a bidder to corner the auction and thus require different levels of effort from the seller to deter cornering. We consider three different types of auctions: the pay-your-bid or "discriminatory" auction commonly used...

This paper considers a uniform-price auction in which each of n symmetric bidders can place, say, M bids. Each bidder has privately known, decreasing marginal values from an arbitrary M -dimensional distribution. We provide a quantile-type description of the asymptotic price that appropriately...

Given an externality function that implements a social objective, this paper examines the possibility of implementing the social objective when the action is observed with error. Provided that the signal is informative in the sense that it separates certain distributions of actions and agents...

Auctioneers often face the decision of whether to bundle two or more different objects before selling them. Under a Vickrey auction (or any other revenue equivalent auction form) there is a unique critical number for each pair of objects such that when the number of bidders is fewer than that...

In this note we examine four standard multi-unit sealed-bid auctions in the presence of synergy. The structure of the equilibrium bidding strategy under each rule is quite intuitive. Whether the equilibrium involves "bundle-bidding" or "separating-bidding" strategy depends on the presence of the...

There are a number of examples in the auction literature (Perry and Reny, 1999, and Krishna, 2002) where releasing the seller's private information can lead to a lowering of expected revenue. On the other hand, releasing information always increases welfare. Levin and Smith (1994) point out that...
