In Internet auctions, it is easy for a bidder to submit multiple bidsunder multiple identifiers (e.g., multiple e-mail addresses).If only one good is sold, a bidder cannot make any additional profit by using multiple bids. However, in combinatorial auctions, where multiplegoods 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 problemson false-name bids.
