摘要: We investigate revenue guarantees for auction mechanisms in a model where distribution is specified each bidder, but only some of the distributions are correct. The subset bidders whose correctly (henceforth, "green bidders") unknown to auctioneer. question we address whether auctioneer can run mechanism that guaranteed obtain at least as much revenue, expectation, would be obtained by running an optimal on green only. For single-parameter feasibility environments, find answer depends constraint. matroid using all (including incorrect ones) expectation bidders. any constraint not matroid, there exists way setting and true such opposite conclusion holds.
