A growth-decomposition (scale, technique and composition effect) covering 62 countries and 7 manufacturing sectors over the 1990-2000 period shows that trade, through reallocations of activities across countries, has contributed to a 2-3 percent decrease in world SO2 emissions. However, when...

We propose and solve a simple model of firm-level decisions to offshore production stages of lower skill intensity than that of activities that remain in the domestic location. In theory, offshoring is optimal only for the more productive among heterogeneous firms if it entails a fixed cost. In...

Multi-sector versions of the international trade model of Eaton and Kortum (2002) usually restrict trade elasticities to be identical across sectors, with potentially distorting effects on the estimates of the model parameters. This paper allows for heterogeneous sectoral trade elasticities and...
