This article compares centralized with disconnected markets in which n2 strategic agents trade two perfectly divisible goods. In a multi-goods uniform-price double auction (centralized market) traders can make their demand for one good contingent on the price of the other good. Interlinking...

I use a sequential-auction model to mimic the environment of Internet auction sites, such as eBay. For a sequence of auctions, new buyers may enter the auction site after some of the auctions has completed and only bid for the remaining auctions. Because an incumbent buyer may have revealed...

We study a symmetric private value auction with signaling, in which the auction outcome is used by an outside observer to infer the bidders' types. We elicit conditions under which an essentially unique D1 equilibrium bidding function exists in four auction formats: first-price, second-price,...

This paper develops one possible argument why auctioning licenses to op-erate in an aftermarket may lead to higher prices in the aftermarket comparedto a more random allocation mechanism. Key ingredients in the argumentare differences in firms' risk attitudes and the fact that future market...

This paper studies markets plagued with asymmetric information on the quality of traded goods. In Akerlof's setting, sellers are better informed than buyers. In contrast, we examine cases where buyers are better informed than sellers. This creates an inverse adverse selection problem: The market...

According to the so-called Exclusion Principle (introduced by Baye et alii, 1993), it might be profitable for the seller to reduce the number of (fullyinformed) potential bidders in an all-pay auction. We show that the Exclusion Principle does not apply if the seller regards the bidders' private...

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...

I study the interaction between optimal procurement and outsourcing of production in small industries. First, two sellers decide about outsourcing. By outsourcing, a seller loses information about the costs of producing to his supplier. Then the buyer designs the procurement mechanism and...

Auctions are a popular and prevalent form of trading mechanism, despite the restriction that the seller cannot price-discriminate among potential buyers. To understand why this is the case, we consider an auction-like environment in which a seller with an indivisible object negotiates with two...
