We study procurement auctions under favoritism and a two-stage decision rule. Because of favoritism, the minimum quality required in order to approve a project is endogenously determined to benefit the recipient of the agency s bias. We show that, even with ex-ante symmetry and independence between the distributions of costs and quality, equilibrium bidding behavior will be asymmetric and the favorite firm will bid less aggressively than the others. A mechanism design approach indicates that revealing the number of qualified participants or adopting a second-price rule would decrease expected prices and costs of realizing the project, due to the elimination of the asymmetric bidding behavior. Finally, simulations for the uniformly distributed case show that while adopting one of the alternative rules increases efficiency, it also increases the favorite firm s ex-ante profits and therefore may facilitate collusion between the agency and a firm.
