In an electronic auction protocol, the main participants are the seller, a set of trusted auctioneer(s) and the set of bidders. In this paper we consider the situation where there is a seller and a set of n bidders intending to come to an agreement on the selling price of a certain good. Full private or bidder-resolved auction means that this agreement is reached without the help of trusted par...

In electronic commerce markets, agents often should acquire multiple resources to fulfil a high-level task. In order to attain such resources they need to compete with each other. In multi-agent environments, in which competition is involved, negotiation would be an interaction between agents in order to reach an agreement on resource allocation and to be coordinated with each other. In recent ...

B2C electronic commerce is commonly viewed as a straightforward browsing and purchase process. Current search tools assisting shoppers limit the automatic comparison of products to the price of goods. Allowing merchants to successfully employ differentiation strategies online requires providing the web with semantic content that can represent merchants’ offers and be automatically processed by ...

Electronic commerce is a rapidly growing area accompanied by the growth of the Internet and the World Wide Web. As information on the Internet becomes more dynamic and heterogeneous , `software agents' have been touted as the new building blocks for a new Internet structure. We foresee a future whereby the Web is populated with as many software agents (involved in electronic commerce and other ...

We study electronic bidding and contracting for nonstorable goods such as electric power using multi-GA agents and game theoretical approaches. In this framework, there is a long-term contract market as well as a back-stop spot market. Seller agents bid into an electronic bulletin board their contract offers in terms of price or capacity, while Buyer agents decide how much to contract with Sell...

The Internet allows for A2A commerce at an unprecedented scale; anyone can do business with anyone. The new markets made possible by the Internet bring with them new challenges. This paper presents a system for buyers in electronic markets to avoid bad sellers by modeling the reputation of a seller. The model proposed by Cohen and Tran [6] is extended to provide a method for the exchange of ind...

Business-to-business (B2B) exchanges are expected to bring about lower prices for buyers through reverse auctions. Analysis of such settings for seller pricing behavior often points to mixed-strategy equilibria. In real life, it is plausible that managers learn this complex ideal behavior over time. We modeled the two-seller game in a synthetic environment, where two agents use a reinforcement ...

Improved consumer addressability in electronic markets allows vendors to send focused promotional messages to specific customers, facilitating a targeted advertising approach that we call “narrowcasting”. We characterize a rational consumer’s market participation decision and identify a narrowcasting firm’s optimal targeting decision when buyers face nontrivial search costs. In the special case...
