MATLAB Simulation Code File.

The MATLAB® (The Mathworks Inc.) code for simulating one migration is provided as supporting information for public use. Both n and α can be easily modified for comparative dynamics analysis. An animated applet for a fixed group size and different values of α has been uploaded at http://www.complejidadsocial.cl/2012/projects/paradigm-shifts/ for readers to visually grasp both micro and macro dynamics of individual paradigm shifts under our framework.
