A nonlinear dynamics for risk contagion: analyzing the not risk-free equilibrium
In this paper we perform the stability analysis of the risk-free equilibrium point which characterizes a financial contagion dynamics. The model is formulated in the Susceptible-Infected-Recovered approach by employing an analogy between economic sectors and ecosystems. The
