Trade and Technology from a Schumpeterian Perspective

This paper attempts to implement empirically a Schumpeterian model of international trade. After briefly discussing the literature on trade and technology, we formulate a model in which 'real' factors such as R&D expenditures, investment and wage costs have an impact on bilateral trade flows between advanced economies. We also take into account the effect of exchange rate differences. The model is empirically estimated on sectoral data for nine OECD countries. We find that what determines competitiveness differs by sector. In many sectors, either R&D expenditures or wage costs are important. The results for investment indicate a weaker role. Consistent with the Marshall-Lerner logic, we find that the sign of exchange rate changes varies by sector. We conclude the paper by a discussion of the relevance of the results for 'technology-based' theories of international trade.
