The Composition of the Human Capital Stock and the Factor Content of Trade: Evidence from West(ern) Germany

This study reports the results of a factor content analysis of the sources of West Germany's comparative advantage in 1976, 1980 and 1984, using highly disaggregated skill variables. The county is found to be most abundant in certain skilled manual occupations and a very limited number of professional and technical occupations. The results differ markedly from those reported in similar studies for the UK and the US. The importance of intercounty productivity diferences and the implications of using only a subset of the economy, i.e. manufacturing, in the calculations are assessed. While using only a subset of the economy might have been appropriate in the past when services trade was relatively unimportant, this is no longer the case, especially for Germany with its diferent performance in goods and services trade. It is argued that the explanatory power of comparative advantage as a basis for trade among similarly developed countries is much higher than is commonly perceived when human capital is disaggregated into detailed skill categories that allow the recognition of different skill mixes between countries. The use of a disaggregated ‘labour-based’ neoclassical trade theory is advocated.
