The ‘Shill Bidding Effect’ Versus the ‘Linkage Principle’

  • Laurent Lamy


The analysis of second price auctions with externalities is utterlymodied if the seller is unable to commit not to participate in themechanism. For the General Symmetric Model (Milgrom and Weber[20]) and standard auction formats, we charaterize the full set of symmetricpure strategy equilibria with shill bids from the seller (usingpossibly mixed strategy) and compare those equilibria to the optimalone with the ability to commit not to use shill bids. The benets fromthe highlighted 'Linkage Principle' are counterbalanced by the 'ShillBidding Eect' which grows with the winner's curse.
