FEEM Working Paper No. 62.2001
We consider two ascending auctions and show that many of the (unwanted) collusive or signaling equilibria studied in the literature in the framework of the SEAMO (simultaneous English auction for multiple objects) don't have a counterpart in the JAMO (Japanese auction for multiple objects). We show however that certain retaliatory equilibria do exist in both auctions.
