Multi-Attribute Community Detection in International Trade Network

Identifying the Community Structure of the International-Trade Multi Network

We study the community structure of the multi-network of commodity-specific trade relations among world countries over the 1992-2003 period.

We also compare them with exogenous community structures induced by geographical distances and regional trade agreements. We find that commodityspe...

Here we use network models to describe the evolution of a particular economic system, namely the International Trade Network (ITN). Previous studies often assume that globalization and regionalization in international trade are co...
