Chaos in Two-Party Democracies

  title={Chaos in Two-Party Democracies},
  author={Alessandro Colombo and Sergio Rinaldi},
  journal={I. J. Bifurcation and Chaos},
In two-party democracies (e.g. US and UK) the two parties often alternate at the government almost periodically. Here, we present a very simple continuous-time model with three state variables (social welfare and size of the lobbies associated with the two parties) that explains this tendency to cyclic behavior. However, the analysis of the model shows that when the lobbies are unbalanced, much more complex behaviors, including chaos, can emerge. The bifurcation structure of the system is… CONTINUE READING
