Abrégé

The present invention primarily concerns hybrid auctions that may, for example, combine a clock auction with a proxy auction. Hybrid auctions include multi-item auctions that comprise at least two phases of package auctions: an earlier phase in which bidders participate in a clock auction (or other dynamic auction); and a later phase in which bidders participate in a proxy auction (or some other package auction). By combining the earlier phase and the later phase as in some of the embodiments described herein, it is possible to combine the advantages of the dynamic auction and the advantages of the sealed-bid package auction. In particular, if the earlier phase is a clock auction and the later phase is a proxy auction, then the resulting hybrid auction will combine the transparency and simplicity of the clock auction with the efficient outcome and competitive revenues of the proxy auction.

The present invention is a system and method for a computer-implemented auction wherein a hybrid auction combining elements of a clock auction and a proxy auction. In particular, if the earlier phase (104) is a clock auction and the later phase (108) is a proxy auction, then the resulting hybrid auction will combine the transparency and the simplicity of the clock auction with the efficiency outcome and competitive revenues of the proxy auction. The system includes receiving bids (118), determining an outcome (134) and outputting the results (136).

An improved system and method for a computer-implemented auction in which multiple types of items are auctioned together without imposing a particular division of supply or demand among the individual types of items. In some embodiments the auction of the present invention provides a means or method for establishing prices for the types of items, wherein the prices maintain a relationship. In other embodiments, the present invention provides a means or method for implying prices from price parameters in the bids received form bidders, based on a relation among the prices for the types of items. Market clearing may be defined by the condition that the aggregate quantity bid for all types of items is less than or equal to the available quantity of all types of items. The division among the types of items within is thus determined flexibly, based on the bids at the associated prices. In other embodiments, market clearing is defined by the condition that the quantity bid for one selected type of item is less than or equal to the available quantity of the selected type of item. The quantities of the other types of items are thus determined flexibly, based on the bids at the associated prices.

n) are employed by bidders, the computer (30) is employed by the auctioneer, and the server (10) is the auction computer. That server consist of a CPU (11), memory (12), a data storage device (13), a communication interface (140), a clock (150), an operating system (16), and an auction program (17). In one embodiment, the system architecture is as a client-server system: the auction computer is a server; and the bidder and auctioneer are clients.
