Fig. 2

The multiplex global financial network for 2018. The size of a node is proportional to its degree. For visualization purposes, we show only edges whose weight is ten or more times larger than the mean weight of the edges in the layer. We color the edges based on the natural logarithm of their weight; darker colors indicate larger weights. In the left panel, we show the edge-colored multigraph on which we run MultiRank. In the right panel, we also include interlayer edges that encode the vertical contagion mechanism in our threshold model. All layers have the same layout; in other words, the position of a country is the same in each layer. We label the countries on which we focus our discussion. To avoid overcrowding the figure with labels and because countries have the same positions in all layers, we only label each country in one layer. [We produced the network visualizations using PYMNET (Kivelä 2014) and added labels with INKSPACE.]
