This study provides a simple, many-industry model of trade which emphasizes the interaction between cross-country technical heterogeneity (i.e., a Ricardian aspect) and monopolistic competition among producers of differentiated products (i.e., a Chamberlinian aspect) as determinants of trade...

This note proposes a three-country model of monopolistic competition that captures the role of time zones in the division of labor. The connectivity of business service sectors via communications networks (e.g. the Internet, satellite communications systems) is found to determine the structure...

The paper develops a model of international trade with increasing returns to scale by taking into account the possibility of cooperation among agents in an egalitarian economy. It is shown that each country gains from trade in a trading world in which there are arbitrary numbers of...

This paper derives sufficient conditions under which the Law of Comparative Advantage and the General Law of Comparative Advantage are true when the preferences of the trading countries may not be represented by "well-behaved" social utility functions. It shows that in the neoclassical framework...

Much of the comparative statics of trade theory rests on the unrealistic assumption that in each trading country all households are alike or behave collectively as though they are alike. In the present paper the authors show that two well-known comparative statical propositions are highly...
