The truthful mechanisms of such an auction are characterized, in the sense that, under standard assumptions, we prove that it is impossible to design a non-trivial truthful auction which allocates all items, while we provide the design of an asymptotically revenue-maximizing truthful mechanism which may allocate only some of the items. Our asymptotic parameter is a budget dominance parameter which measures the size of the budget of a single agent relative to the maximum revenue. We discuss the relevance of these results for the design of online ad auctions.}, url = {http://approjects.co.za/?big=en-us/research/publication/multi-unit-auctions-budget-constrained-bidders/}, pages = {44-51}, edition = {Proceedings of the 6th ACM Conference on Electronic Commerce (EC)}, }
