Under plausible assumptions about preferences and technology, the model in this paper suggests that the entire volume of world trade matters for wage inequality. Therefore, trade integration, even among identical countries, is likely to increase the skill premium. Further, we argue that...

We argue that, with an elasticity of substitution in consumption greater than one and higher scale economies in the skill-intensive sectors, the entire volume of world trade matters for wage inequality. This implies that trade integration, even among identical countries, is likely to increase...

We construct and estimate a unified model combining three of the main sources of cross-country income disparities: differences in factor endowments, barriers to technology adoption and the inappropriateness of frontier technologies to local conditions. The key components are different types of...
