Preferential Attachment

..or the rich get richer!

Think of preferential attachment as an attribute of when 'the rich get richer' within a networked system. This occurs when nodes that have a lot of links tend to attract more links as other nodes enter the system resulting in super-nodes.


 In a networked system, nodes that have a lot of links tend to attract more links as other nodes enter the system. As a result, 'super nodes' with a higher Fitness appear to hold a disproportionate number of links. The resulting {{networks}} tend to follow a 'POWER-LAW DISTRIBUTION'.

    Across the globe we find spatial clusters of similar economic activity. How does complexity help us understand the path-dependent emergence of economic clusters?

    Evolutionary Economic Geography (EEG) tries to understand how economic agglomerations or clusters emerge from the bottom-up. This branch of economics draws significantly from principles of complexity and emergence, seeing the rise of particular regions as being path-dependent, and trying to understand the forces at work that drive change for economic agents - the firms that make up our economic environment.

    Complex Systems can unfold in multiple trajectories. However, there may be trajectories that are more stable or 'fit'. Such states are considered 'attractor states'.

    Complex Adaptive Systems do not obey predictable, linear trajectories. They are "Sensitive to Initial Conditions", whereby small changes in these conditions can lead the system to unfold in entirely unexpected ways. That said, some of these 'potential unfoldings' are more likely to occur than others. We can think of these as 'attractor states' to which a system - out of all possible states - will tend to gravitate. Learn more →
