We address the scheduling problem of reordering an existing queue into its efficient order through trade. To that end, we consider individually rational and balanced budget direct and indirect mechanisms. We show that this class of mechanisms allows us to form efficient queues provided that...

A crucial assumption in the optimal auction literature has been that each bidder's valuation is known to be drawn from a single unique distribution. In this paper we relax this assumption and study the optimal auction problem when there is ambiguity about the distribution from which these...

We analyze optimal trading mechanisms in environments where each trader owns some units of a good to be traded and may be either a seller or a buyer, depending on the realization of privately observed valuations. First, the concept of virtual valuation is extended to ex ante unidentified...

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 book is a non-technical introduction to auction theory; its practical application in auction design (including many examples); and its uses in other parts of economics. It can be used for a graduate course on auction theory, or – by picking selectively – an advanced undergraduate or MBA...

This paper studies multiple object auctions when there are two kinds of bidders: those interested in the bundle being sold (bundle bidders) and those that want one specific object only (unit bidders). The analysis has been motivated by the sale of spectrum rights in the United States.Using a...

I consider a model where a principal decides whether to produce one unit of an indivisible good (e.g. a private school) and which characteristics it will contain (emphasis on language or science). Agents (parents) are differentiated along two substitutable dimensions: a vertical parameter that...

A firm can merge with one of n potential partners. The owner of each firm has private information about both his firm’s stand-alone value and a component of the synergies that would be realized by the merger involving his firm. We characterize incentive-efficient mechanisms in two cases....
