We consider a dynamic model of network formation where agents form and sever links based on the centrality of their potential partners. We show that the existence of capacity constrains in the amount of links an agent can maintain introduces a transition from dissortative to assortative networks. This effect can shed light on the distinction between technological and social networks as it gives a simple mechanism explaining how and why this transition occurs. Key words: Bonacich centrality, network formation, social interactions, nested split graphs JEL: A14, C63, D85 6 We are grateful to the editor and two anonymous referees for helpful comments.
On the other hand, networks that evolved with constraints (with respect to the number of links a node can maintain) tend to transition from being dissortative to assortative with time REF .
