Network Externalities and Comparative Advantage


  • Kikuchi, Toru


In this article I examine how the network externalities of communications activities and trading opportunities interact to determine the structure of comparative advantage. These interactions are examined by constructing a two-country, three-sector model of trade involving a country-specific communications network sector. The role of the connectivity of network providers, which allows users of a network to communicate with users of another network, is also explored.
