In the post-war period, the goods composition of trade in OECD countries has changed considerably. We analyze the evolution of comparative advantage using a detailed trade data set and a new analytical tool: the harmonic (weighted) mass index, which enables us to identify periods of structural...

The trade literature often treats countries as dimensionless points, which is a strong assumption. Agglomeration or lumpiness of production factors within countries can affect the national pattern of trade. In this paper we analyze comparative advantage patterns for 22 cities and 4 regions for...

Traditional trade theory assumes that countries are dimensionless points. Recent research shows, however, that the internal geography of countries is important for the effects on trade. One aspect of internal geography is the uneven spatial distribution of factors of production. Factors of...
