More generally, complexity economics models are often used to study how non-intuitive results at the macro-level of a system can emerge from simple interactions at the micro level. This avoids assumptions of the [[representative agent]] method, which attributes outcomes in collective systems as the simple sum of the rational actions of the individuals. | More generally, complexity economics models are often used to study how non-intuitive results at the macro-level of a system can emerge from simple interactions at the micro level.
