Under recurrent procurement, the awarding of a contract to a firm may put it in an advantageous position in future tenders, which may reduce competition over time. The objective of this paper is to study the dynamics of competition for tendered contracts, focusing on factors that may generate...

A buyer with downward slopping demand faces a number of unit supply sellers. The paper characterizes optimal auctions in this setting. For the symmetric case, a uniform auction (with price equal to lowest rejected offer) is optimal when complemented with reserve prices for different quantities...

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...

This paper considers the social costs implied by inefficient allocation of contracts in a first price, sealed bid procurement auction with asymmetric bidders. We adopt a constrained (piecewise linear) strategy equilibrium concept and estimate the structural parameters of the bidders'...

Within the framework of the common value model, we examine the magnitude of the difference in expected outcome between first-price and second-price sealed bid auctions. The study is limited to two empirical specifications of bidders' signals: Weibull and normal distribution. The optimal bid...

This paper considers procurement auctions with costly bidding when the auctioneer is unable to commit himself to restrict the number of bidders. The auctioneer can, however, offer a financial reward to be paid to every short-listed bidders as an indirect commitment device. Rewards for...

A budget-constrained buyer wants to purchase items from a shortlisted set. Items are differentiated by quality and sellers have private reserve prices for their items. Sellers quote prices strategically, inducing a knapsack game. The buyer's problem is to select a subset of maximal quality. We...

A budget-constrained buyer wants to purchase items from a short-listed set. Items are differentiated by observable quality and sellers have private reserve prices for their items. The buyer's problem is to select a subset of maximal quality. Money does not enter the buyer's objective function,...

We consider procurement of an innovation from heterogeneous sellers. Innovations are random but depend on unobservable effort and private information. We compare two procurement mechanisms where potential sellers first bid in an auction for admission to an innovation contest. After the contest,...

We present a new dynamic auction for procurement problems where payments are bounded by a hard budget constraint and money does not enter the procurer's objective function.
