Linking Absolute and Comparative Advantage to Intra-Industry Trade Theory*

Two countries, which differ with respect to domestic demand for two groups of differentiated products, are considered in a setting of monopolistic competition where international trade is subject to transaction costs. It is shown that relative differences in demand determine the trade pattern. Each country is a net exporter of that group for which domestic demand is relatively larger-where the country has a comparative home-market advantage. Absolute differences in demand determine relative wages. Thus, the paper argues that the notions of absolute and comparative advantage as found in traditional trade theory also have meaning in new trade theory.
