The study addresses the issue of sustainability of collusion in one-sided auctions. Earlier experimental studies indicate that, in double oral auctions, collusion is hard to sustain even if conspiracy is allowed and quotation improvement rules are absent. We investigate the role of similar...

We investigate bidder collusion in one-sided ascending price auctions without communication. If bidding rules in an English-type auction allow bidders to match each others' bids, collusion can be sustained as a Nash equilibrium of a one-shot auction game. Our earlier experiments show that in...
