ABSTRACT
The theory of complexity is emerging as a new unifying theory for understanding endogenous change and transformation across a variety of disciplines ranging from mathematics and physics to biology. The theory of complexity favours a systemic and dynamic approach: systemic in that the outcome of the behaviour of each agent and of the system into which each one is embedded can only be understood as the result of the interaction between micro-and macrodynamics; and dynamic because it makes it possible to understand the structural change that stems from the interaction of agents.
