SUMMARY:Networks: Contagion and Resilience - Sanjeev Goyal\, Professor of 
 Economics\, University of Cambridge

DESCRIPTION:Connections between individuals (persons\, firms\, banks\, cit
 ies and countries) facilitate the exchange of goods\, resources and inform
 ation but they also expose an individual to threats and dangers faced by o
 thers.\n\nA key element is that linking activity and investments in securi
 ty are purposeful and take into account the activities of others. In some 
 contexts threats are random (e.g.\, biological viruses or liquidity shocks
  to banks) while in others (e.g.\, hackers\, criminals and military) the t
 hreats come from an ``intelligent'' adversary. As we vary the decision mak
 ing powers regarding links and security and the nature of the threats\, we
  trace out an ensemble of theoretical scenarios. A network is said to be r
 esilient if it performs `well' in the face of threats.\n\nI will talk abou
 t on-going work in which we:\n# Develop an economic framework for the stud
 y of resilient networks.\n# Develop general methods to solve models of res
 ilience.\n# Apply these methods in applications in epidemiology\, infrastr
 ucture\, security and finance.\n
