Abstract This paper describes the bid signaling that occurred in many of the FCC spectrum auctions. Bidders in these … auctions bid on numerous spectrum licenses simultaneously, with bidding remaining open on all licenses until no bidder is …

We study auctions where bidders have independent private values but attach a disutility to the surplus of rivals, and … derive symmetric equilibria for first-price, second-price, English, and Dutch auctions. We find that equilibrium bidding is … more aggressive than standard predictions. Indeed, in second-price auctions it is optimal to bid above one's valuation …

innovation is obtained, auctions licenses to a pool of producers. Each producer has a private valuation for the license and …

auctions---as the result of other bidders trying to avoid stimulating the victim into learning more about his value. The idea …

I study affiliated, pure common-value auctions with ex-ante asymmetric buyers. For the two-buyer case I characterize … and prove uniqueness of the equilibrium of hybrid auctions where the payment is a weighted average of the highest and …
