Abstract

We study the feasibility, challenges, and potential benefits of adding a lottery component to standard negotiated and rule-based procurement procedures. For negotiated procedures, we introduce a “discrete lottery” in which local bureaucrats negotiate with a small number of selected bidders and a lottery decides who is awarded the contract. We show that the discrete lottery performs better than a standard negotiated procedure when the pool of firms to choose from is large and corruption is high. For rule-based auction procedures, we introduce a “third-price lottery” in which the two highest bidders are selected with equal probability and the project is contracted at a price corresponding to the third highest bid. We show that the third-price lottery reduces the risks from limited liability and renegotiation. It performs better than a standard second-price or ascending auction when the suppliers’ pool size, the risk of cost overrun, delays and non-delivery of the project are high. The choice between a second-price auction, a third price lottery and a lottery amongst all bidders also depends on the weight placed on producer surplus, including for instance the desire to increase the participation of local SMEs in public sector services markets.
