An improved multidimensional auction is provided which simplifies the bidder's bidding strategy by performing an adjustment of the initial bids. This adjustment is designed to reduce bidder's incentives to make bids dependent on competitor's expected bids. This is accomplished by the following. A utility function is generated based on the buyer's preferred terms for purchasing a product. The utility function is then applied to initial bids received from one or more sellers of the product to generate a ranking of the initial bids. Finally, the winning bid selected based on the ranking is adjusted to generate an adjusted bid. The adjusted bid is higher than the second highest bid, but lower than the winning bid. As a result, the improved multidimensional auction of the present invention allows for a faster auction process that takes into account buyers' preferences and performs at least as well or outperforms Vickrey and English auctions. It provides fewer incentives to find out the competitor's bids, thus simplifying the optimal bidding strategy. In some embodiments, all of the initial bids -- not just the winning bid -- are adjusted in such a manner as to preserve the ranking of the initial bids. In some embodiments, the adjusted bids are presented to the buyer using a unique format for all bids in a given rank class. Finally, in some embodiments, the initial ids are adjusted using predefined business rules. |
