Mechanisms for network contraction

Felix Reed-Tsochas
University of Oxford

Starting from an empirically well-characterised example of significant contraction in a socio-economic network over an extended period of time, I identify the selection processes that appear to be operating, and extend these to a more general model of network contraction. My particular focus is on the robustness of the network under contraction, and the microscopic mechanisms favouring disassortative links that generate this behaviour.
