The economy, and indeed life itself, is increasingly dependent on an intricate web of critical infrastructure systems. The failure or damage of electric power, telecommunications, transportation and water supply systems would cause huge economic disruptions far larger than one might initially expect. Although the work on the resilience of complex networks has triggered enormous interest and debate, most studies have been focused on single isolated networks. Such a situation is, however, more an exception than the norm. Infrastructures show a large number of interdependencies of a different nature: in the world economy, it seems increasingly true that "everything depends on everything else". In this project we will seek new ways to hedge against the intrinsic new risks arising from high-frequency trading. Understanding the interdependence of networks and the effect of inter-dependence on the robustness of economic/financial systems is our overall goal.
