We prove that the English auction (with bidders that need not be ex ante identical and may have interdependent valuations) has an efficient ex post equilibrium. We establish this result for environments where it has not been previously obtained. We also prove two versions of the...

We compare, experimentally, the Vickrey auction and an ascending-price auction recently introduced by Ausubel (1997). We evaluate the relative performance of both auctions in terms of efficiency and revenue in multi-unit environments where valuations either have a common-value component or are...

The seller of N distinct objects is uncertain about the buyer's valuation for those objects. The seller's problem, to maximize expected revenue, consists of maximizing a linear functional over a convex set of mechanisms. A solution to the seller's problem can always be found in an extreme point...

This article reviews recent developments in revealed preference theory. It discusses the testable implications of theories of choice that are germane to specific economic environments. The focus is on expected utility in risky environments, subjected expected utility and maxmin expected utility...
