Within developing and newly industrialized countries, rising wage inequality is both common and highly correlated with export growth. This is incompatible with the Stolper-Samuelson theorem, but suggestive of a role for technological catch-up. We develop this insight using a model that features...

Do scale economies contribute to our understanding of international trade? Do international trade flows encode information about the extent of scale economies? To answer these questions we examine the large class of general equilibrium theories that imply Helpman-Krugman variants of the Vanek...
