Combines economics with computer science to analyse multidimensional auction mechanisms, the emerging pricing model for e-business. For professionals, consultants and dotcomers involved in designing, implementing and upgrading electronic markets, as well as researchers in: economics, information...

The Combinatorial Clock Auction is a two-stage auction format, which has been used to sell spectrum licenses worldwide in the recent years. It draws on a number of elegant ideas inspired by economic theory. A revealed preference activity rule should provide incentives to bid straightforward,...

Core-selecting combinatorial auctions are being used in an increasing number of spectrum sales worldwide. It was shown that equilibrium strategies can lead to outcomes that are further from the core than the Vickrey outcome in sealed-bid auctions. Ascending core-selecting auctions can even lead...

Motivated by markets for television advertising time-slots, we introduce a new combinatorial auction format, including a general method for approximating core-selecting payments for hard problems. Given the size and complexity of ad markets in practice, an enumerative XOR bidding language...
