We consider a two good world where an individual i with income mi has utility function u (x, y), where x ∈ [0, ∞) and y ∈ {0, 1}. We first derive the valuation (maximum price that he is willing to pay for the object) for good y as a function of his income. Then we consider the following...

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 compares the equilibrium outcomes from a recently developed model of procurement competition with differentiated products to those from two analytically tractable models that might naturally be considered as suitable proxies. The models differ in what sellers know about the buyer's...

The present paper analyzes a general class of first-price all-pay auctions where two players have different "bidding technologies" and one bidder has a head start advantage over his/her opponent. Prize values are common knowledge and may be different between the players. Equilibria are...

In the context of first-price auctions with asymmetrically informed bidders, we show that risk aversion not only increases a player's bid, but also makes him less sensitive to the probability that other bidders are informed about his private valuation

This paper analyzes bidding fee auctions --- an auction format in which bidders pay a fee every time they bid. In these auctions, the prize value diminishes as the auction progresses, and the person who pays the most does not necessarily win. Bidding fee auction websites are an increasingly...

Second price allpay auctions (wars of attritions) have an evolutionarily stable equilibrium in pure strategies if valuations are private information. I show that for any level of uncertainty there exists a pure deviation strategy close to the equilibrium strategy such that for some valuations...

We analyze the effects of mergers in first-price sealed-bid auctions on bidders' equilibrium bidding functions and on revenue. We also study the incentives of bidders to merge given the private information they have. We develop two models, depending on how after-merger valuations are created. In...

This paper analyzes bidding behavior in oil and gas tract auctions in Brazil, where the main winner has been Petrobras, a national company. We test predictions from the theory of common -value, first -price, sealed -bid auctions with asymmetric information. The tests indicate that Petrobras was...

This paper considers equilibrium behavior in a descending price auction with two players that are asymmetrically informed. The "informed" player knows his valuation while the other does not. The uninformed player can acquire information about his valuation with a positive cost during the...
