Low-revenue equilibria allow participants in an auction to obtain goods at prices lower than would prevail in a competitive market. These outcomes are generated as perfect equilibria of ascending-bid, multiunit auctions. We show that these equilibria are possible under mild...

Each year, multi-stage auctions of one form or another sell or let billions of dollars worth of goods and contracts. Yet despite the significance of such auctions, the existing theory of auctions and competitive bidding fails to explain why a bid taker might prefer a multi-stage auction to a,...

Auctions and bidding models are attracting an ever increasing amount of attention. The Stark and Rothkopf (Stark, R. M., M. H. Rothkopf. 1979. Competitive bidding: a comprehensive bibliography. Oper. Res. 27 (2) 364--390.) bibliography includes approximately 500 works in the area. Additional...

The theory of auction design examines how various factors affect the outcome of an auction. Most of the existing literature focuses on how varying the amount of information available to each bidder affects the bid-taker's expected revenue when all other factors remain constant. This paper...

We investigate the effect of regret-related feedback information on bidding behavior in sealed-bid first-price auctions. Two types of regret are possible in this auction format. A winner of the auction may regret paying too much relative to the second highest bid, and a loser may regret missing...

Increasingly simulations have been required as supportive evidence to management of proposed system changes. It has long been recognized that the computer running costs of simulations are strongly influenced by the synchronization mechanism used. Recently the time indexed list has been proposed...

This paper presents an equilibrium explanation for the persistence of naive bidding. Specifically, we consider a common value auction in which a "naive" bidder (who ignores the winner's curse) competes against a fully rational bidder. We show that the naive bidder earns higher equilibrium...

One of the goals of procurement is to establish a competitive price while affording the buyer some flexibility in selecting the suppliers to deal with. Reverse auctions do not have this flexibility, because it is the auction rules and not the buyer that determines the winner. In practice,...

Concurrent auctions of several objects are traditionally analyzed as if they were independent single-object auctions. Such an approximation may be very crude if bidders have budgetary restrictions, capacity constraints, or, in general, have non-linear utility functions. This paper presents a...

While most models of auctions and competitive bidding assume that each bidder's utility for an outcome depends only on his own profit, we allow the utility to also depend on any regret that a bidder suffers after the fact and characterize when and how this affects bidding. Specifically, a winner...
