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...

Low-revenue equilibria allow participants in an auction to obtain goods at prices lower than would prevail in a competitive market. These outcomes are generated as perfect equilibria of ascending-bid, multiunit auctions. We show that these equilibria are possible under mild...
