In many auctions, a good match between the bidder and seller raises the value of the contract for both parties although information about the quality of the match may be incomplete. This paper examines the case in which the bidder is better informed about the quality of his match with the seller...

After the close of an auction, the winning bidder may find that he is unable to carry out his bid offer. This paper seeks to determine what measures the seller should take to maximize his share of the surplus when bidders are privately informed about their risk of default. Special attention is...

In many auctions, matching between the bidder and seller raises the value of the contract for both parties. However, information about the quality of the match may be incomplete. We consider the case in which each bidder observes the quality of his match with the seller but the seller does not...

This paper studies equilibria of second price auctions in independent private value envi- ronments with different participation costs. Two types of equilibria are identified: monotonic equilibria in which a bidder with a lower participation cost results in a lower cutoff for sub- mitting a bid,...

In an auction with a buy price, a seller offers bidders the opportunity to forgo competing in an auction by transacting immediately at a pre-specified fixed price. If a seller has aspirations in the form of a reference price that depends upon the auction's reserve price and buy price, she does...

In this paper we analyze incentives for a potential entrant to get into an oligopolistic Cournot-like market by taking over one of the incumbents and we derive the conditions under which the hostile merger is possible and profitable. The key-feature is that the target of the takeover is...

We consider a second price auction between bidders with independently and identically distributed valuations, where a losing bidder suffers a negative direct externality. Considering ex-ante commitments to form bidding rings we study the question of core stability of the grand coalition, namely:...

Maskin and Riley (2003) and Lebrun (2006) prove that the Bayes-Nash equilibrium of �rst-price auctions is unique. This uniqueness requires the assumption that a buyer never bids above his value. We demonstrate that, in asymmetric �rst-price auctions (with or without a minimum bid), the...

Several new auction formats are spreading over the Internet. They have usually the aim of raising revenues by increasing the number of participant, who will pay a participation fee, rather than selling the object at the highest possible price. The aim of this paper is to study a format of...

The paper compares different auction formats for sale of a single patented innovation for budget constrained bidders. This unit decreases the marginal cost of production in the aftermarket for its owner by an amount which depends on the money invested on the development of this technology. As...
