The spectrum for third generation (3G) mobile communications for the German market was alloted to operators by means of an auction. This resulted in a highly competitive outcome: six operators were given rights to provide 3G services. Government revenues from this auction were a staggering EUR...

This contribution revisits the problem of allocating R&D subsidies by government agencies. Typically, the applicants' financial constraints are private information. The literature has recommended the use of auctions in order to reduce information rents and thus improve the efficiency of how...

This article studies the design of optimal mechanisms to regulate entry in natural oligopoly markets, assuming the regulator is unable to control the behavior of firms once they are in the market. We adapt the Clarke-Groves mechanism, characterize the optimal mechanism that maximizes the...

We analyze the problem of selling shares of a divisible good to a large number of buyers when demand is uncertain. We characterize equilibria of two popular mechanisms, a fixed price mechanism and a uniform price auction, and compare the revenues. While in the auction truthful bidding is a...

This paper considers one-sided scheduling problems, where a schedule of service is arranged at one location, without regard to other schedules. Typically, such scheduling problems are handled on a first-come-first-serve basis, which is grossly inefficient. The present paper proposes a scheduling...

In multi-unit auctions, such as auctions of commodities and securities, and financial exchanges, it is necessary to specify rationing rules to break ties between multiple marginal bids. The standard approach in the literature and in practice is to ration marginal bids proportionally. This paper...

If bidders are uncertain whether the auctioneer sticks to the announced reserve, some bidders respond by strategic non-participation, speculating that the auctioneer may revoke the reserve. However, the reserve inadvertently signals the auctioneer's type, which drives a unique separating and a...

A principal uses security bid auctions to award an incentive contract to one among several agents in the presence of hidden action and hidden information. Securities range from cash to equity and call options. "Steeper" securities are better surplus extractors that narrow the gap between the two...
