| Summary: | This article seeks to study how intra-OECD trade in manufacturing goods has affected technological heterogeneity across member states during 1988-2008. To this aim, we derive a panel data version of the Eaton and Kortum (2002) normalised trade model to estimate, annually, the technological heterogeneity of OECD countries. We find a gradual technological convergence across the group as the sensitivity of intra-group trade to price factors increases over time. However, the results diverge when considering European and non-European OECD sub-samples, separately. We find that technological convergence is not an automatic result of intra-group trade but, for that, a more general programme of economic liberalisation, including free movement of capital and labour, is also required
