In this sequel to a companion paper, the authors complement the analysis of the binary projections of the International Trade Network (ITN) by considering its weighted representations. They show that, unlike the binary case, all possible weighted representations of the ITN (directed/undirected, aggregated/ disaggregated) cannot be traced back to local structural properties, which are therefore of limited informativeness. The results highlight that any topological property representing only partial information (e.g., degree sequences) cannot in general be obtained from the corresponding weighted property (e.g., strength sequences). Therefore the expectation that weighted structural properties offer a more complete description than purely topological ones is misleading.
