Abstract

This paper incorporates Melitz's Econometrica (71:1695-1725, 2003) heterogeneous-firm trade model in the Ricardian model of comparative advantage with a continuum of sectors introduced by Dornbusch et al. (Am Econ Rev 67(5), 823-839, 1977). In particular, we characterise the equilibrium outcomes when neither sectors nor countries are symmetric. We find that trade patterns can follow Ricardian comparative advantage, while wage rates are proportional to market size due to a home market effect. Interestingly, trade liberalisation hurts the large country but benefits the small one by reducing the number of sectors with two-way trade and expanding those with specialised (one-way) trade.
