English auctions and the Stolper-Samuelson theorem
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 Stolper-Samuelson theorem, one for economies with n goods and n factors, and one for non-square economies. Similar as...
متن کاملComparative Statics, English Auctions, and the Stolper-samuelson Theorem
We introduce a comparative-statics observation; we prove that the English auction is efficient in a model with interdependent valuations and n bidders; we generalize the StolperSamuelson Theorem to the case of more than 2 goods and factors of production and to non-square economies; and we illustrate how our comparative-statics observation is behind those seemingly unrelated economic proposition...
متن کاملThe effectiveness of English auctions
We study the performance of the English auction under different assumptions about the seller’s degree of “Bayesian sophistication.” We define the effectiveness of an auction as the ratio between the expected revenue it generates for the seller and the expected valuation of the object to the bidder with the highest valuation (total surplus). We identify tight lower bounds on the effectiveness of...
متن کاملSecure Online English Auctions
Security and privacy in online auctions is a major concern as auction participants have many opportunities to cheat (e.g., repudiate bids, not deliver items, etc.). Online auctions such as those used by eBay are based on a type of auction referred to as an English auction. Dispite the English auction being the most popular type of auction, it has received less security coverage than other types...
متن کاملAsymmetric English Auctions Revisited
I introduce a property of players valuations that ensures the existence of an ex post e¢ cient equilibrium in asymmetric English auctions. The use of this property has the advantage of yielding an ex post e¢ cient equilibrium without assuming di¤erentiability of valuations or that signals are drawn from a density. These technical, non economic, assumptions have been ubiquitous in the study of ...
