Non-performing loans, systemic risk and resilience in financial networks [pdf]Paper  abstract   bibtex   
The present work investigates the relationship between non-performing loans and systemic risk using a network-based approach. In particular, we analyze how an increase in NPLs at firm level propagates to the financial system through the network of credits and debits. To this end we develop a model with two types of agents, banks and firms, linked one another in a two-layers structure by their reciprocal credits and debits. The model is analyzed via numerical simulations and allows to define a synthetic measure of systemic risk and to quantify the resilience of the financial system to external shocks. For illustrative purposes, in we present an application of the model to Italy, Germany, and United Kingdom, using empirically observed data for the three countries.
