"Lock-in" vs. "critical masses" - industrial change under network externalities

Article Abstract:

An analysis of the role of networking in the dissemination of new technology reveals that technological 'lock-in' or the monopoly of one entity of the new technology for a period can be challenged by the capacity of the technology to reach a 'critical mass' where a number of agents determine the entry of a new technology. Technology 'lock-ins' are rare and a closer analysis reveals that technological change is determined by a number of potential adopters.
