Correlations of Value Added Growth in the World Trade Network — Julian Maluck1,2 and •Reik V. Donner1 — 1Potsdam Institute for Climate Impact Research, Potsdam, Germany — 2Tokyo Institute of Technology, Tokyo, Japan
International trade has grown considerably during the process of globalization. Complex supply chains for the production of goods have resulted in an increasingly connected International Trade Network [1]. Here, we investigate empirically to what extent the topological properties of the ITN provide information about the correlations in the production of two industry sectors. We observe that although direct trade relations between industries serve as important indicators for correlations in the industries' value added, opportunities of substitution for required production inputs as well as second-order trade relations cannot be neglected. Our results contribute to a better understanding of the relation between trade and economic productivity. They serve as a basis for more accurate modeling techniques and better interpretation of the impacts of a node's failure due to economic crises.
