It is generally thought that market outcomes are improved with the provision of market information. As a result, the use of repeated rounds with price feedback has become standard practice in the applied experimental auction valuation literature. We conducted two experiments to determine how...

In a menu auction, players submit bids for all choices the auctioneer A can make, and A then makes the choice that maximizes the sum of bids. In a binomial menu auction (BMA), players submit acceptance sets (indicating which choices they would support), and A chooses the option that maximizes...

Climate change, security and cost of energy supplies, and the competitiveness of firms and economies have been focal points of the general political and economic policy debate in recent years. This article examines the choices in this field made at global level with the Kyoto Protocol and in...

This paper presents a game theoretic analysis of the generalized second price auc- tion that the company Overture operated in 2004 to sell sponsored search listings on its search engine. We present results that indicate that this auction has a multi- plicity of Nash equilibria. We also show that...

Web sites invest significant resources in trying to influence their visibility among online search results. In addition to paying for sponsored links, they invest in methods known as search engine optimization (SEO) that improve the ranking of a site among the search results without improving...

Often an auction designer has the option of selling, or purchasing, those lots available in one auction or a sequence of auctions. In addition, bidder opportunities will not be static, in part due to arrival of information, but also because bidders can face deadlines for making decisions. This...

Consider an all-pay auction with interdependent, affiliated valuations and private budget constraints. We characterize a symmetric equilibrium for the case of two players. In contrast with the second-price auction, making budgets more severe can depress the bids of unconstrained bidders

In the world the use of auctions has shown two important trends: 1. their use has been extended to a greater number of countries and sectors, 2. the set of objects auctioned has increased exponentially. Colombia is not an exception. The number of auctions and items in the country is huge, the...

Recent papers show that all-pay auctions are better at raising money for charity than first-price auctions with symmetric bidders and under incomplete information. Yet, this result is lost with sufficiently asymmetric bidders and under complete information. In this paper, we consider a framework...

This paper gives two examples to break through the revelation principle. Furthermore, the revenue equivalence theorem does not hold.
