How different are the production functions of the European manufacturing sectors? New empirical evidence

The neo-classical model of international trade assumes that the Total Factor Productivity (TFP) of a sector is common across countries, that returns to scale are constant and that the sectoral production of the countries differs by virtue of the factor endowments. In this article, we consider whether the differences in production can also be explained by the economies of scale in the national industries and by the technological differences across countries. To test this hypothesis, we estimate three models proposed in Harrigan (1999) with data for eight European Union (EU) Member States covering the period 1978 to 1992 and analyse how the TFP changes from country to country.
