Colombian export capabilities: building the firms-products network Matteo Bruno,1 Fabio Saracco,1 Tiziano Squartini,1 and Marco Due˜ nas2 1 IMT School for Advanced Studies, P.zza S.

Our analysis depicts a strongly modular system, with several groups of firms specializing in the export of specific categories of products. These clusters have been detected by running the bipartite variant of the traditional modularity maximization, revealing a bi-modular structure. Interestingly, this finding is refined by applying a recently-proposed algorithm arXiv:1809.03222v1 [physics.soc-ph] 10 Sep 2018 for projecting bipartite networks on the layer of interest and, then, running the Lou
