This dissertation studies the spread of crisis over the financial system. More specifically, we aim to develop models that allow us to simulate how an economic shock strikes a few financial agents and from them propagate over the system, becoming a systemic problem. The dissertation is composed by the introduction and by two chapters. In the first chapter, we model the spread of crisis over investment funds using network science. Combining two models of propagation in financial networks, one simulating the propagation of losses in bipartite networks of assets and financial agents and the other simulating the propagation of losses in a network of cross-holdings of shares among financial agents, we develop an algorithm to simulate the spread ...
