This study explores stability in efficient collusion in government procurement auctions. In first- and second …-price auctions with independent private values, we look at the possibility of vetoing collusion mechanisms and the learning of the …

This paper explores the impact of debarment as a deterrent of collusion in first-price procurement auctions. We develop … a procurement auction model where bidders can form bidding rings, and derive the bidding and collusive behavior under no … both reduce collusion and bids. The deterrent effect of debarment increases in its length. However, the debarment of …
