Recent auction theory and experimental results document strategic demand reduction by bidders in uniform-price auctions. The present article extends this area of research to consider the effects of varying the number of bidders. Our theoretical model predicts that demand reduction should...

We study a common value auction in which two bidders compete for an item the value of which is a function of three independent characteristics. Each bidder observes one of these characteristics, but one of them is 'naive' in the sense that he does not realize the other bidder's signal contains...

We consider multiunit auctions in which there are enough units so that each bidder but one wins every unit on which he bids. We characterize the equilibrium bidding strategy for three different payment rules: the pay-your-bid auction, the uniform-price auction in which the price equals the...
