Figure 6: Collective dynamics in simulated and real interacting networks.
From: Multiple tipping points and optimal repairing in interacting networks
(a) Simulation of the networks’ dynamics, activity versus time, for N=100 and failure parameters 
, rA=rB=0.60 and rd=0.15 shows the switching of the system between four different states. We can easily identify four collective states: 11, 22, 12 and 21. (b) Dynamics of two CDS geographical networks consisting of 17 European and 8 Latin American countries, showing very similar behaviour: individual networks switching between well-defined high-activity and low-activity states, as well as correlated collective behaviour of the two networks in interaction. We identify collective states 11, 22, 12 and 21, and mark them with connected black ovals. It is noteworthy that, as the CDS value grows with risk, a higher activity in a CDS network corresponds to bad economic news.
