This paper is about a procurement auction setting, introduced in Gal-Or, Gal-Or and Dukes (2007), in which suppliers offer differentiated products and the buyer needs to decide whether to reveal or not to the suppliers the own preferences for the various products. We provide some technical...

We consider an asymmetric auction setting with two bidders such that the valuation of each bidder has a binary support. We prove that in this context the second price auction yields a higher expected revenue than the first price auction for a broad set of parameter values, although the opposite...

A buyer needs to procure a good from either of two potential suppliers offering differentiated products and with privately observed costs. The buyer privately observes the own valuations for the products and (ex ante) decides how much of this information should be revealed to suppliers before...

In this work we show that the separation property identified in the franchise bidding literature depends strictly on the hypothesis of coincidence of the regulator's beliefs with those of the competing firms. Nevertheless, in many contexts it is more truthful to hypothesize that the regulator's...

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...

This work studies a reverse auction in which a buyer needs to acquire a given good or service from suppliers having different costs. The sellers are characterized by qualities that are the buyer’s private information. Comparing the outcomes of different policies regarding the revelation of...

Procurement auctions often involve quality considerations as a determinant of the final outcome. When qualities are the procurer’s private information then various information policies may be used to affect the expected outcome. For auctions with two cost heterogeneous suppliers, this work...

We study a model of procurement auctions in which information policies can be used to treat two heterogeneous suppliers asymmetrically. The buyer is shown to be better off revealing information about her preferences to the weak supplier only, when there is a sufficient cost difference between...
