From: Crisis contagion in the world trade network

Fig. 4

(Left) Total number τ of crisis contagion stages as a function of the bankruptcy threshold κ and (right) total crisis cost C as a function of the bankruptcy threshold κ. The total cost C is defined according to the formula (7), i.e., C(κ)=C(κ,τ). We use the WTN for years 2004 (black), 2008 (red), 2012 (blue), and 2016 (green). Solid lines correspond to the model A: once a country goes to bankruptcy, it is prevented to import products with the exception of petroleum and gas. Dashed lines correspond to the model B: once a country goes to bankruptcy, it is prevented to import any product. The lines allow to adapt an eye between the dots which represent the numerically computed values. The total amount of the World Trade transactions is V=9.43×1012 USD in 2004, 1.68×1013 USD in 2008, 1.85×1013 USD in 2012, and 1.62×1013 USD in 2016. The damping factor is α=0.5
