International trade: global value chains. An aproximation from network theory

Based on techniques of the network analysis, the hierarchies and relative
positions attained by countries in the global value chains formed by bilateral
trade (2005-2009) are studied. The propose methods solve some limitations
of the traditional networks analysis toolbox, facing directly the structural asymmetry
and the double counting in the international trade. The methodology
allows us to set-up statistical criteria of the reliability of the center-periphery
hypothesis to this case, and an accurate estimation of those structures. The
results show that core role of United States and Germany in global value chains
and the different role of the technology intensity levels.
