As massively multi-player gaming environments become more detailed, developing agents to populate these virtual worlds as capable non-player characters poses an increasingly complex problem. Human players in many games must achieve their objectives through financial skills such as trading and supply chain management as well as through combat and diplomacy. In this paper, we examine the problem ...

Evolving e-commerce technologies increasingly enable organisations to participate in different types of network forms or in electronic markets with previously unidentified trading partners. Virtual organisations (VO) take different forms, have varying lifecycles and involve different scope and depth of relationships. This paper examines the literature in terms of the terminology of virtual orga...

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...

We model the availability of product information in Internet-based markets, and explain the underlying causes for the phenomenon of less than perfect information available to consumers of products and services in these markets. We use Salop’s model of product differentiation and explore the conditions under which sellers make horizontal information available to buyers. We demonstrate that under...

The Internet revolution brought about significant changes in the availability of market information to consumers in many industries. This research examines technology-driven changes in market transparency, defined as the ability of market participants to observe information about products and prices. The objective is to develop a modeling and empirical basis for a theory of market transparency ...

We propose an electronic institution approach to build a virtual market as an open multi-agent system that handles several negotiation protocols in a coherent and flexible fashion. This proposal has been inspired by the work in mWater, which is developed as a regulated environment where autonomous agents trade rights for the use of water in a closed basin. We also present a generic negotiation ...

While functional regression models have received increasing attention recently, most existing approaches assume both a linear relationship and a scalar response variable. We suggest a new method which extends the usual linear regression model to situations involving both functional responses, Xj(t), and functional predictors, Y (t). Our approach uses a penalized least squares optimization crite...
