Job Creation and Trade in Manufactures: Industry-Level Analysis Across Countries

This paper examines industry-level responses of manufacturing employment in the context of globalization using a large sample of developed, developing, and transition economies. We find that developing countries need atypically high rates of value-added growth (about 10 %) to increase manufacturing employment appreciably (about 4 %). The employment benefits of export orientation are also modest even in “comparative advantage” industries of developing countries. However, diversifying the export basket contributes significantly to employment growth, particularly in the medium- and high-technology industries. Import competition does not undermine employment growth in low-technology industries of developing countries while it displaces jobs in the same industries in Organisation for Economic Co-operation and Development (OECD) and transition economies. For developing countries, import-induced job losses are higher in the more capital-intensive medium-technology industries. Jobs in high-technology industries are less sensitive to imports with positive relationships observed in the OECD. Investment also complements job creation in low-technology industries of developing countries that have yet to industrialize

We show the dynamics of sectoral production- structural change- come with systematic changes in the geographic dispersion of activity. In developing countries, sectoral diversification is accompanied by geographic agglomeration, and regions become heterogeneous. In advanced economies, sectoral specialization is accompanied by geographic dispersion, and regions become homogeneous. We argue that developing countries diversify because their constituent regions integrate with each other, and can specialize regionally as a result. Advanced economies specialize because they integrate internationally and their constituent regions all produce according to the global pattern of comparative advantage. We find systematic support for these claims in international data on sectoral production at the regional level, including in the US, China and India, but no such evidence once the samples focus on non-traded sectors or relatively closed regions. Economic areas formed by specialized, regionally homogeneous countries tend to diversify and agglomerate, as if their constituent countries were integrating

International audienceThis paper studies the evolution of sectoral labor concentration in relation to the level of per capita income. We show that various measures of sectoral concentration follow a U-shaped pattern across a wide variety of data sources: countries first diversify, in the sense that labor is spread more equally across sectors, but there exists, relatively late in the development process, a point at which they start to specialize again. We introduce a model with endogenous costs of trading internationally that provides an explanation for this new empirical fact. The model highlights a trade-off between the benefits of diversification in the context of high trading costs, and the benefits of specialization in a Ricardian sense

This paper studies the evolution of sectoral concentration in relation to the level of per capita income. We show that various measures of sectoral concentration follow a U-shaped pattern across a wide variety of data sources: countries first diversify, in the sense that economic activity is spread more equally across sectors, but there exists, relatively late in the development process, a point at which they start specializing again. We discuss this finding in light of existing theories of trade and growth, which generally predict a monotonic relationship between income and diversification.
