I analyze the salient features of networks and point out the similarities between the economic structure of networks and the structure of vertically related industries. The analysis focuses on positive consumption and production externalities, commonly called network externalities. I discuss...

This paper critiques some of the properties of the so-called quot;efficient component pricing rulequot; (ECPR) for access to a bottleneck (monopoly) facility. When a rival and the bottleneck monopolist both produce a complementary component to the bottleneck service, the ECPR specifies that the...

In this paper we present a generalisation of GAMETH framework, that play an important role in identifying crucial knowledge. Thus, we have developed a method based on three phases. In the first phase, we have used GAMETH to identify the set of “reference knowledge”. During the second phase,...

In a knowledge management project, the key issue is to help the stakeholders to choose which parts of their knowledge will need to be specifically capitalized. This means finding a decision support approach enabling them to identify and locate potential crucial knowledge. To deal with this type...

Knowledge is not manageable as if it was a data or information. Consequently, Knowledge Management (KM) must address activities that utilize and create knowledge more than knowledge by itself. With regard to this issue, we elaborated a sociotechnical approach of Knowledge Management within the...

Environment is a broad and complex issue. It is likely be inaccessible to most laypersons, whereas, environmental experts are likely to have a limited field of expertise. Hence, there is a need for comprehensive and accurate environmental information in many situations. This research aims at...

Very often, Knowledge Management System is considered from a technological viewpoint that induces to consider the knowledge as an object, and so to disregard the importance of people. In this paper we suggest a global vision of Knowledge Management within the Enterprise that is represented by an...
