• Contagion
• interbank networks
• systemic risk

Starting from the growing body of literature on contagion in financial networks, the work provides a computational model of interbank network with the aim of studying how a shock (represented by the failure of a given number of firms) affects the whole system in terms of frequency and extent of contagion. Different settings of the model are proposed to study to what extent the outcomes of the computer simulations depend on finer details like the assumptions about balance sheet managements in bankruptcy events. Taking as benchmark the work of Gai and Kapadia (2010), we will provide a more deep microfuondation by incorporating the real side of the economy and analyzing how the interaction between banks and firms affect the final outcome.
