Auctions have been getting increasing attention in computer science and economics, as they provide an efficient solution to resource allocation problems with self-interested agents. E-Commerce and finance have emerged as some of their largest application fields. The need for new auction mechanisms that allow complex bids such as bundle or multi-attribute bids has been raised in many situations....

Auction-based models and protocols introduce money and pricing as the technique for coordination between users and producers of resources in grids. In this paper, we propose a multi-attribute reverse auction protocol to allocate grid resource. In order to enhance the information efficiency we develop a novel interactive approach supporting both user agents and producer agents. In this approach,...

Auctions and negotiations are mechanisms used in market exchanges. Behavioral economics experiments focused on the mechanism efficiency which required highly simplified problems and contexts. This paper discusses an on-going project involving an experimental comparison of auction and negotiation mechanisms embedded in software which we have developed. The experiments are situated in an e-busine...

Spectrum is a valuable, scarce and finite natural resource that is needed for many different applications, so efficient use of the scarce radio spectrum is important for accommodating the rapid growth of wireless communications. Spectrum auctions are one of the best-known market-based solutions to improve the efficiency of spectrum use. However, Spectrum auctions are fundamentally differen...

Today’s supply chains require more dynamic trading practices to better match suppliers with their customers. Additionally, the purchase decisions faced are rarely made on price alone; but rather on a bundle of attribute values. With ubiquitous computing and Internet connectivity, newer types of negotiation are emerging such as reverse auctions. This paper presents a heuristic algorithm for mult...

We study probabilistic single-item second-price auctions where the item is characterized by a set of attributes. The auctioneer knows the actual instantiation of all the attributes, but he may choose to reveal only a subset of these attributes to the bidders. Our model is an abstraction of the following Ad auction scenario. The website (auctioneer) knows the demographic information of its impre...

Eli M. Snir Introduction Online, industrial, procurement auctions are becoming a standard component in many companies’ purchasing toolbox. Companies seek to enjoy the benefits of the marketplace by implementing competitive bidding strategies among their supply base. Recent surveys of industry practices indicate that up to 52% use some form of online auction (Beall et al, 2003), with an average ...

In this paper, we present an agent which is able to negotiate the buying and selling of imperfectly sustitutable goods in a double auction style market. Two goods are said to be imperfectly substitutable if a buyer can use either of them, but prefers one over the other. For example, an electronics manufacturer using a RAM chip can use many suppliers to do this but may be willing to pay a premiu...

In this paper we consider a procurement multi-attribute English auction with a deadline. This protocol can be used for agents who try to reach an agreement on an item or issue, which is characterized by several quality attributes in addition to the price. The protocol allows the specification of a deadline since in many real world situations it is essential to conclude a negotiation among agent...
