Generalization of the MV Mechanism

Unknown author (2008-05-01)

Micali and Valiant proposed a mechanism for combinatorial auctions that is dominant-strategy truthful, guarantees reasonably high revenue, and is very resilient against collusions. Their mechanism, however, uses as a subroutine the VCG mechanism, that is not polynomial time.We propose a modification of their mechanism that is efficient, while retaining their collusion resilience and a good fraction of their revenue, if given as a subroutine an efficient approximation of the VCG mechanism.
