Fig. 5

The number of systemically important countries (which we abbreviate as “systemic countries” in the axis label) over time in the multiplex global financial network and in its associated monolayer networks. We show simulations on the multiplex global financial network (which we abbreviate by “Mx” in the legend) using dashed curves and simulations on the monolayer networks using dotted curves. For the multiplex network, blue, reddish orange, purple, and black curves correspond to vertical thresholds of 0.33, 0.50, 0.66, and 0.80, respectively. For the monolayer networks, brown, green, blue, and black curves correspond to the equity, debt, banking, and aggregate networks, respectively
