Collusion in private value ascending price auctions

Abstract

We investigate the effects of bid improvement rules and bidder value asymmetry on bidder collusion in experimental ascending price auctions without communication. We find that the strict bid improvement rule and private values are not always sufficient to break collusion among well-motivated bidders. Collusion still occurs as long as bidder gains from collusion are high.
