Changes in the International Pattern of Factor Abundance and the Composition of Trade

摘要

The paper assesses the role of changes in relative resource supplies across countries as an explanation of the changing structure of U.S. trade and the growing competition to United States producers in international markets since the early 1960s. Although focusing primarily on the United States, the analysis also considers the impact of changing resource supplies on the trade structure of thirty-three other countries. In so doing, the analysis provides a basis for understanding the impact of relative resource changes on U.S. comparative advantage within the world economy.
