Las externalidades de las economías de la red: el caso de la telefonía movil

The complexity of the current economic relations, created in part by the rapid change of technology, offers real challenges to study and understand the behavior of economic agents. Many of these problems and their solutions have to do with the way in which the complexity of the involved systems is analyzed. In particular, the economic systems whose dynamics is the result of the interaction of the processes of positive and negative feedback have been widely used in the economic analysis. As a classic example, we have the model of supply and demand whose dynamic nature is the result of the interaction of these processes.This paper analyzes one of forces of positive feedback such as the primary network and secondary network economies. The first type refers to the increased value received by the consumer as the number of users increases while the second one refers to the establishment of a complementary base that can reduce the transaction costs for consumers and increase the value captured by the supplier. By using as reference the classic model of Harold Hotelling, the externalities of network economies are modelled as a force of positive feedback since these forces play a determinant role in an oligopolistic market with a dominant agent –a market structure that describes in general the competition in the mobile phone industry in MexicoJournal: Revista de Administración, Finanzas y Economía (Journal of Management, Finance and Economics)
