We give necessary and sufficient conditions for the existence of symmetric equilibrium without ties in common values auctions, with multidimensional independent types and no monotonic assumptions. When the conditions are not satisfied, we are still able to prove the existence of pure strategy...

In this paper we characterize the optimal allocation mechanism for $N$ objects, (permits), to $I$ potential buyers, (firms). Firms' payoffs depend on their costs, the costs of competitors and on the final allocation of the permits, allowing for externalities, substitutabilities and...

Most of the literature on auctions assumes that the auctioneer owns the object on sale. However most auctions are organized and run by an agent of the owner. This separation generates the possibility of corruption. We analyze the effect of a particular form of corruption on bidding behavior in a...

When a partnership comes to an end partners have to determine the terms of the dissolution. A well known way to do so is by enforcing a buy/sell option. Under its rules one partner has to offer a price for the partnership and the other agent can choose whether she wants to sell her share or buy...

This paper analyzes bidding behavior in a multi period multiple unit auction. While bidders are ex ante symmetric, the first period outcome translates the second period game to a game between asymmetric bidders. The first period outcome determines who will be a strong or a weak bidder in the...

Sellers benefit on average from revealing information about their goods to buyers, but the incentive to exaggerate undermines the credibility of seller statements. When multiple goods are being auctioned, we show that ordinal cheap talk, which reveals a complete or partial ordering of the...

Within the independent private-values paradigm, we derive the data-generating process of the winning bid for the last unit sold at sequential English auctions when bidder valuations are draws from one of several different classes of distributions; i.e., in the presence of asymmetries. When the...

We analyze the two-bidder discriminatory auction with downward sloping marginal valuations and a continuous, variable award. We allow for a common component in marginal valuations and affiliation. We focus on problems that admit solutions with strictly downward sloping bidding schedules. Using...

We consider a model where bidders in an auction own passive partial claims over their rivals’ auction profits. While the cross ownership confers no ability to directly affect bidding behavior, the claims on rival profits dampen bidding competition. It is not uncommon for enforcement agencies...

The use of dynamic auctions is a major component in many enterprises' e-procurement initiatives. In the case where suppliers offer goods and services of inherently different quality the traditional mechanism has been the request for quote. In a request for quote, suppliers submit a sealed bid...
