We characterize truthful mechanisms in two multi-parameter domains. The first characterization shows that every mechanism for combinatorial auctions with two subadditive bidders t...
Roberts’ theorem from 1979 states that the only incentive compatible mechanisms over a full domain and range of at least 3 are weighted variants of the VCG mechanism termed affin...
We exhibit three approximation algorithms for the allocation problem in combinatorial auctions with complement free bidders. The running time of these algorithms is polynomial in ...
This paper presents a secure Generalized Vickrey Auction (GVA) scheme that does not require third-party servers, i.e., the scheme is executed only by an auctioneer and bidders. Com...
Combinatorial auctions, where bidders can submit bids on bundles of items, are economically efficient mechanisms for selling items to bidders, and are attractive when the bidders...
