Beyond chopsticks: Symmetric equilibria in majority auction games

چکیده

Majority auction games are simultaneous sealed-bid auctions of identical objects among identical bidders who each want to win a specified fraction (more than a half) of the objects. Each bidder receives no benefit from winning less than the specified fraction and no additional benefit from winning more than it. Symmetric equilibria having simple, intuitive forms are shown to exist in firstprice, second-price and all-pay versions of such games when the number of bidders is sufficiently large. This contrasts with earlier results for the two-bidder “pure chopstick” majority auction games where the only known equilibria are more complicated.  2003 Elsevier Inc. All rights reserved.

Three-object two-bidder simultaneous auctions: chopsticks and tetrahedra

Symmetric equilibria are constructed for a class of symmetric auction games. The games all have two identical bidders bidding in three simultaneous first-price sealed-bid auctions for identical objects. Information is complete and the bidders’ marginal valuations increase for the second object and then decrease for the third. In all cases the support of the mixture that generates the equilibriu...

First-price auction symmetric equilibria with a general distribution

In this paper I obtain the mixed strategy symmetric equilibria of the first-price auction for any distribution. The equilibrium is unique. The solution turns out to be a combination of absolutely continuous distributions case and the discrete distributions case.

Using Simultaneous Best Response to Find Symmetric Bayes-Nash Equilibria in Auctions

Finding Nash and Bayes-Nash equilibria in games is a hard problem both analytically and computationally. We restrict out attention to symmetric Bayes-Nash equilibria in auctions and propose a computational method that takes advantage of the symmetry of equilibria and structure of auction games. The method is iterated best-response where all players move simultaneously. We present experimental r...

Two-Object Two-Bidder Simultaneous Auctions

Symmetric equilibria are constructed for a class of symmetric auction games. The games all have two identical bidders bidding in two simultaneous sealed-bid auctions for identical objects. Information is complete and the objects are either complements or substitutes. In both cases a continuum of mixed-strategy equilibria are identified. All these equilibria have a surprising structure: The supp...

On the continuous equilibria of affiliated-value, all-pay auctions with private budget constraints

We consider all-pay auctions in the presence of interdependent, affiliated valuations and private budget constraints. For the sealed-bid, all-pay auction we characterize a symmetric equilibrium in continuous strategies for the case of N bidders. Budget constraints encourage more aggressive bidding among participants with large endowments and intermediate valuations. We extend our results to the...
