Crisis contagion network for years 2004, 2008, 2012, and 2016. The colors of country nodes range from red, for countries going to bankruptcy at stage τ=0, to blue, for countries going to bankruptcy at stage τ=τ. White nodes corresponds to countries which never go to bankruptcy. The direction of the link between two countries A and B is given by its curvature. If A points to B following the bent path in the counterclockwise direction (A B) then A went to bankruptcy at the stage just before B, otherwise, i.e. (A B), B went to bankruptcy at the stage just before A. The color of the link is the color of the node source. The width of the link is proportional to the export volume from the target country to the source country in the unmodified WTN. Here, once a country goes to bankruptcy, it is prevented to import products with the exception of petroleum and gas (model A). The bankruptcy threshold is κ=0.1 and the damping factor is α=0.5
