In many auctions, the auctioneer is an agent of the seller. This delegation invites corruption. In this paper we propose a model of corruption, examine how corruption affects the auction game, how the anticipation of corruption affects bidding, and how it altogether changes the revenue ranking...

The second-generation GSM spectrum auction in Germany is probably the most clear cut example of a low price outcome in a simultaneous ascending-bid auction.The present paper gives an account of the events, describes the auction rules and market conditions, and provides a theoretical explanation...

The third generation UMTS auction in Germany raised an enormous amount of revenue, and at the same time achieved a more competitive market structure than other UMTS auctions in Europe. The present paper explains the design of that auction, and presents a game theoretic explanation of observed...

This paper gives an account of events, and explains some systematic reasons of the UMTS auction flop in Switzerland. Apart from general market developments, which could not have been anticipated, we argue that auctiondesign which was introduced in England and adopted in Switzerland and elsewhere...

We consider takeover bidding in a Cournot oligopoly when firms have private information concerning the synergy effect of merging with a takeover target. Two auction rules are considered: standard first-price and profit-share auctions, supplemented by entry fees. Since non-merged firms benefit...

We consider the procurement of a complex, indivisible good when bid preparation is costly, assuming a population of heterogeneous contractors. Shortlisting is introduced to implement the optimal number of bidders, and we explore whether the procurer should reimburse the nonrecoverable cost of...

We review different kinds of corruption that have been observed in procurement auctions and categorize them. We discuss means to avoid corruption, by choice of preferable auction formats, or with the help of technological tools, such as secure electronic bidding systems. Auctions that involve...
