A profit-maximizing Seller has a single unit of a good to sell. The bidders have a pure common value that is drawn from a distribution that is commonly known. The Seller does not know the bidders' beliefs about the value and thinks that the information structure is chosen adversarially by Nature...

We study the mechanism design problem for a seller of an indivisible good in a setting where privately informed buyers can acquire additional information and refine their valuations for the good at a cost. For this setting, we propose optimal (revenue-maximizing) and efficient...

A profit-maximizing Seller has a single unit of a good to sell. The bidders have a pure common value that is drawn from a distribution that is commonly known. The Seller does not know the bidders' beliefs about the value and thinks that beliefs are designed adversarially by Nature to minimize...

We analyze a divisible good uniform-price auction that features two groups each with a finite number of identical bidders and present conditions under which a unique privately revealing equilibrium exists. We derive novel comparative static results highlighting that increases in transaction...

We analyse an endogenous prize all-pay auction under complete information where it is possible that none of the bidders wins and the winning payoff becomes non-monotonic in own bid. We derive the conditions for the existence of pure strategy equilibria and fully characterize the unique mixed...

The answer is no. Although naive intuition may suggest the opposite, uncertainty about costs in the homogeneous-good Bertrand model intensifies competition: it lowers price and raises total surplus (but also makes profits go up). For some economic environments, this is implied by Hansen's (RAND,...

This paper studies complete-information, all-pay contests with asymmetric players competing for heterogeneous prizes. In these contests, each player chooses a performance level or "score". The first prize is awarded to the player with the highest score, the second -- less valuable -- prize to...

In this paper, we examine the optimal mechanism design of selling an indivisible object to one regular buyer and one publicly known buyer, where inter-buyer resale cannot be prohibited. The resale market is modeled as a stochastic ultimatum bargaining game between the two buyers. We fully...

We study the efficiency of standard auctions with interdependent values in which one of two bidders is perfectly informed of his value while the other is partially informed. The second-price auction, as well as English auction, has a unique ex-post equilibrium that yields efficient allocation....

We study the optimal entry fee in a symmetric private value first-price auction with signaling, in which the participation decisions and the auction outcome are used by an outside observer to infer the bidders' types. We show that this auction has a unique fully separating equilibrium bidding...
