We study the sale of an indivisible good to liquidity constrained buyers: they cannot pay more than their “budget” regardless of their valuation. Both valuation and budget are private information. We derive the symmetric revenue maximizing and constrained efficient auctions in this setting....

This paper describes a nearly optimal auction mechanism that does not require previous knowledge of the distribution of values of potential buyers. The mechanism we propose builds on the new literature on the elicitation of information from experts. We extend the latter to the case where the...

We consider the problem of mechanism design by a principal who has private information. We point out a simple condition under which the privacy of the principal's information is irrelevant in the sense that the mechanism implemented by the principal coincides with the mechanism that would be...

A seller wishes to sell an object to one of multiple bidders. The valuations of the bidders are privately known. We consider the joint design problem in which the seller can decide the accuracy by which bidders learn their valuation and to whom to sell at what price. We establish that optimal...

A buyer seeks to procure a good characterized by its price and its quality from suppliers who have private information about their cost structure (fixed cost + marginal cost of providing quality). We solve for the optimal buying mechanism, i.e. the procedure that maximizes the buyer’s expected...

In this paper we investigate the exclusion of types in optimal auctions. We show that multidimensional types exclusion is a general phenomenon.

In this paper I first present a new convergence result which will derive an optimal auction mechanism as a limit of standard nonlinear pricing mechanisms. For example, an optimal auction mechanism of Myerson (1981) will be explicitly derived as a limit of nonlinear pricing mechanisms by Mussa...

We analyze optimal schemes for privatization in a transitional economy. In many cases, established Western firms are good candidates for large shareholders of a local firm, since the sale of the shares can generate large amount of revenues and furthermore, in the future, the home country can...

We characterize the optimal selling mechanism in a scenario where similar goods are sold to “high end” buyers through a posted price and to “lower end” buyers through an auction. We show that the optimal mechanism involves an auction which is a standard optimal auction (Myerson (1981))...

We study the design of profit maximizing single unit auctions under the assumption that the seller needs to incur costs to contact prospective bidders and inform them about the auction. When bidders' types are independent (with^Mpossibly bidder-specific distributions) and their valuations are...
