The Combinatorial Clock Auction (CCA) has frequently been used in recent spectrum auctions. It combines a dynamic clock phase and a one-off supplementary round. The winning allocation and the corresponding prices are determined by the VCG rules. These rules should encourage truthful bidding,...

I study auctions in which firms bid for licenses that reduce their marginal costs in a post-auction downstream market. When there are three or more firms, I show that the Vickrey--Clarke--Groves (VCG) auction maximizes consumer surplus in dominant strategies if and only if it maximizes producer...

We show how to bid in first-price auctions when a bidder knows her own value but not how others will bid. To do this we introduce a novel and general method for how to make choices in strategic settings without assuming common knowledge or equilibrium behavior. Accordingly, first eliminate...

The Combinatorial Clock Auction (CCA) has been frequently used in recent spectrum auctions. It combines a dynamic clock phase with subsequent VCG pricing in order to maximize price discovery and efficiency. We inquire into the role of the clock when bidders have lexicographic preferences for...

This paper develops an economic argument relating auctions to high marketprices. At the core of the argument is the claim that market competition andbidding in an auction should be analyzed as part of one game, where the pricingstrategies in the market subgame depend on the bidding strategies...
