In Internet auctions, it is easy for a bidder to submit multiple bids#R##N#under multiple identifiers (e.g., multiple e-mail addresses).#R##N#If only one good is sold, a bidder cannot make any additional profit by using multiple bids. However, in combinatorial auctions, where multiple#R##N#goods are sold simultaneously, submitting multiple bids under fictitious names can be profitable. A bid made under a fictitious name is called a {em false-name bid}. In this talk, I describe the summary of existing works and open problems#R##N#on false-name bids.
