Are there systematic forces such that countries of different sizes participating in a free trade bloc gain differently from the entry of new members? If economies of scale imply that firms located in large countries enjoy lower costs, then the gains from enlarging the bloc will fall...

In a previous analysis of the West African Monetary Union, Macedo(1985a), size is taken to be a major structural characteristic of a country in the sense that large countries are not affected by disturbances originating in small countries but small countries are affected by large countries'...
