Combinatorial auctions permitting bids on bundles of items have been developed to remedy the exposure problem associated with single-item auctions. Given winning bundle prices a set of item prices is called market clearing or equilibrium if all the winning (losing) bids are greater (less) than...

In combinatorial auctions the pricing problem is of main concern since it is the means by which the auctioneer signals the result of the auction to the participants. In order for the auction to be regarded as fair among the various participants the price signals should be such that a participant...

Uniform-price auctions of a divisible good in fixed supply admit underpricing equilibria, where bidders submit high inframarginal bids to prevent competition on prices. The seller can obstruct this behavior by tilting her supply schedule and making the amount of divisible good on offer change...

In this paper the sequence of winning bids in the public auction of used cars in New Jersey is examined for the presence of price anomalies. Unlike many studies of heterogeneous objects where the effect of the order of sale on the price may not be credibly identified, the effect of the order is...

We use a unique hand collected data set of 6 258 auctions from the online football manager game Hattrick to study micro-patterns of reserve price formation. We find that chosen reserve prices exhibit both, very sophisticated and irrational" behavior by the sellers. Reserve prices pick up the...

In January 2007, first evidence of an asymmetric pass-through of CO2 emission allowance prices was reported for the German electricity spot market. This paper explores the theoretical basis for such an asymmetry in the context of a supply function bidding duopoly. It interprets fluctuating...

Ein grundlegendes Ergebnis der Auktionstheorie besagt, dass der Preisverlauf einer sequentiellen Auktion unter üblichen IPV-Annahmen konstant ist und unter Zugrundelegung affiliierter Bewertungen sogar ansteigt. Empirische Arbeiten beobachteten jedoch in der Praxis auf unterschiedlichsten...
