Resumo(s)
International trade in services is becoming an increasingly import topic in trade negotiations. Given the importance of service trade it is somewhat surprising that services, to the extent that they raise issues different from ' goods, have rarely been analysed in formal economic analysis. In this paper, we develop a formal model of international trade in services with three commodities (two standard goods and a service), two factors, and two countries. Trade in the service requires the locational presence of productive factors, without whose physical presence, the service becomes essentially a non-tradeable. We establish conditions for comparative advantage and analyze the pattern of trade in the service. In this model, trade in all commodities cannot occur without factor mobility and it is clear that restrictions on factor mobility can be used as a policy tool to prevent trade in services.
