Abstract
This paper develops a model of international trade with a continuum of countries and sectors, which combines Ricardian comparative advantage and increasing returns to scale. Trade consists of both inter- and intra-industry trade. The model predicts that the trade-weighted Grubel-Lloyd index of intra-industry trade is positively related to the number of exported sectors, and is negatively related to the number of imported sectors. Empirical evidence from a panel of countries using the UN Comtrade database supports these predictions, and the model fits the data better for non-OECD than for OECD countries.
