• The existence of factor intensity reversals between industrial countries has sometimes been attributed to differences in intra-industry specialisation. The industries studied are in fact quite heterogeneous. Consequently the relationships between the specialisation pattern of individual countries and differences in technology between industries may be obscured. In this paper a new method is presented with which specialisation of engineering trade can be studied in great detail. The method rests on the hypothesis that so called (metric) ton prices can be used as a proxy variable for differences in technology in a cross-section of engineering products. This hypothesis is further specified and tested in the paper for a cross-section of engineering products consisting of 40 subindustries of the Swedish engineering industry. If the outcome of the test can be assumed to hold both for a lower level of commodity aggregation and for other countries as well, the new method can be used to test different trade theories (including the factor proportions theory) on the engineering trade of industrial countries. It uses among other variables three variables constructed from the ton prices in engineering exports of OECD-Europe. The results of this paper carry major implications also on the construction and earlier use of price indices of engineering products. The results seem to imply that ton prices fo not measure product prices of engineering goods but rather the technology used in converting tons of metals into units of engineering goods. The price indices used in studies estimating price elasticities in foreign trade or production functions on time series data rest, however, im part on such an assumption.
