We construct a simple firm-based automata model for global economic inter-dependence of countries using modern notions of self-organized criticality and recently developed dynamical-renormalization-group methods (e.g., L. Pietronero et al., Phys. Rev. Lett., 72(11):1690 (1994); J. Hasty and K....

We develop a simple firm-based automaton model for global economic interdependence of countries using modern notions of self-organized criticality and recently developed dynamical renormalization-group methods. We demonstrate how extremely strong statistical correlations can naturally develop...
