The increased use of online market places (like eBay) by professional traders and small businesses goes along with an increase in demand for online multi-unit auction designs. A seller with many objects for sale might consider it inconvenient to initiate and monitor a single auction for each individual item and thus might favour the use of a multi-unit auction. However, the design of online mul...

The theory of procurement auctions traditionally assumes that the offered quantity and quality is fixed prior to source selection. Multi-attribute reverse auctions allow negotiation over price and qualitative attributes such as color, weight, or delivery time.

We discuss the design of a hybrid mechanism for e-procurement, which implements a multi-attribute combinatorial auction, followed by a bargaining process to achieve desirable procurement transaction outcomes. For the auction phase of the mechanism, we discuss incentive-compatible bidding strategies for suppliers, and how the buyer should determine the winning suppliers. In the follow-on bargain...

Abstract We study three alternative implementations of the Vickrey (1961) multi-unit demand auction: Vickrey’s original static sealed-bid auction and two dynamic alternatives, with and without public dropout information reported during the auction (Ausubel, 2004). Although implemented by a weaker solution concept, behavior in the dynamic Vickrey auction with the public dropout information comes...
