Auction

An auction is a method of asset sale by competitive bidding. An auction is most useful when the potential price of the asset to be sold is uncertain. Different auction formats exist, varying according to how prices are quoted and bids tendered. The most commonly known of these is the English Auction, which is commonly used for artworks and wine. This auction is also called the ascending price or open-outcry auction. The best known auction houses, Sothebys and Christies, were founded in the eighteenth century, but written records of auctions go back to ancient times. Economists specializing in game theory have investigated the theory of bidding strategies for an auction, and how these strategies depend upon the rules and procedures of the auction. In the business arena, these experts are sometimes hired as consultants for important auctions, such as when the Unites States government sold wireless spectrum licenses by auction.
