DESCRIPTION:We present a framework for decentralised combinatorial auction
 s and an underlying solution concept called strongness. For bidders with s
 uperadditive valuations\, our framework encompasses some existing auctions
 . For bidders with subadditive valuations\, we develop a new auction under
  the framework above. With submodular valuations and identical items\, und
 er straightforward bidding the revenue generated by the new auction is at 
 least the revenue generated by the VCG mechanism. We show that there are e
 xamples in which the new auction results in a different outcome than the V
 CG mechanism with a revenue strictly greater than that of the VCG assuming
  a straightforward bidding strategy.  (Joint work with Mahyar Salek.)
