This paper considers procurement auctions with costly bidding when the auctioneer is unable to commit himself to …

We present a new dynamic auction for procurement problems where payments are bounded by a hard budget constraint and …

We study procurement auctions in which, as is common in practice, a group of sellers (incumbents, qualified bidders) is …

This paper studies a buyer's procurement strategies in a two-stage supply chain with price-sensitive demand. The buyer … considered. The buyer takes two attributes into consideration when designing the procurement mechanism: quantity attribute (i … the optimal procurement mechanism for the buyer, which consists of a nonlinear menu of contracts for each of the two …

In this paper, we design the optimal procurement mechanisms when bidders are privately informed on efficiency and on … observable but neither verifiable nor contractible quality. We show that most of the optimal procurement institutions are mixed … procedure implying both separation and pooling. Thus, the existing takc-it-or-leave-it offers and procurement auc-tion appear …

equilibrium behavior in asymmetric auctions. We apply these tools to studying procurement auctions in which, as is common in …We provide new tools for studying asymmetric first price auctions, connecting their equilibria to the ρ-concavity of … the underlying type distributions, and showing how one can use surplus expressions for symmetric auctions to bound …
