THE TECHNOLOGY FACTOR AND THE EXPORT PERFORMANCE OF U.S. MANUFACTURING INDUSTRIES

The paper examines two central theories advanced to explain the revealed comparative advantage of U.S. industries. The neo-technological account centers on the process of innovation among industries and is represented in the regression analysis by an R&D intensity variable. The neofactor theory advances both human and "physical" capital as important variables in determining countries' comparative advantage. Foreign protection is postulated to affect the export performance of U.S. industries. Generally the results suggest that U.S. revealed comparative advantage is most pronounced in R&D intensive industries that give the U.S. a temporary technological lead in world markets.
