In this work we compare three alternative procedures aimed at selecting a private partner in PPP projects: i.e. negotiation, auction and competitive negotiation. We show how the suitability of each of these selection mechanisms depends on many economic and institutional factors: e.g. the extent...

We study how poor quality of institution, such as corruption in public procurement auction, could hurt welfare. We show how competition effect could improve the cost-efficiency but not the quality of a public procurement auction with corruption. In fact, no incentive mechanism can be efficient...

We compare two commonly used mechanisms in procurement: auctions and negotiations. The execution of the procurement mechanism is delegated to an agent of the buyer. The agent has private information about the buyer s preferences and may collude with one of the sellers. We provide a precise...

We consider a Green Public Procurement setting where the procurer provides a bid discount to environment-friendly technologies to foster their use. We assume that, before the auction, firms may switch to green technology via a publicly observable costly investment. We show that investment acts...

This paper studies multi-attribute auctions in which a buyer seeks to procure a complex good and evaluate offers using a quasi-linear scoring rule. Suppliers have private information about their costs, which is summarized by a multi-dimensional type. The scoring rule reduces the multidimensional...

We contribute to the literature on the optimal design of auction mechanisms for the procurement of nature conservation activities. We use an economic experiment to examine whether the market efficiency of conservation auctions increases or decreases with repetition. Theory predicts that...

We analyze vertical integration in auction markets using a symmetric independent private-values model where the auctioneer invests in the auctioned object's quality. We find that the auctioneer invests more after integration. The integrated bidder enjoys a bidding advantage over other bidders....

As a selling mechanism, auctions have acquired a central position in the free market economy all over the globe. This development has deepened, broadened, and expanded the theory of auctions in new directions. This chapter is intended as a selective update of some of the developments and...
