Event details

We present a new decentralised combinatorial auction for bidders with subadditive valuations. The auction proceeds in stages where bidders compete over sets allocated to bidders in previous stages. The first stage of the auction considers bids on the sets of all items in the auction; subsequent stages consider bids on progressively smaller subsets of items which bidders allocate to themselves. With submodular valuations and identical items, the revenue generated by the new auction is at least as large as the revenue generated by the VCG mechanism. We show that there are examples in which the new auction can result in a different outcome than that obtained by the VCG mechanism with a revenue strictly larger than that of the VCG mechanism.
