Building on previous works on business fluctuations, we model the propagation of financial distress in a network of regions, each populated by heterogeneous interacting firms and banks. In order to diversify risk, firm sell goods outside their own region and borrow from banks located there....

Building on previous works on business fluctuations, we model the propagation of financial distress in a network of regions, each populated by heterogeneous inter- acting firms and banks. In order to diversify risk, firm sell goods outside their own region and borrow from banks located there....

In this paper we introduce an agent-based model with heterogeneous firms which compare their mutual innovation strategies on different network structures. By implementing a dynamic behavioral switching via a fitness mechanism based on agents performance, companies can endogenously modify their...

Financial institutions form multi-layer networks of contracts among each other and exposures to common assets. As a result, the default probability of one institution depends on the default probability of all the other institutions in the network. Here, we show how small errors on the knowledge...

We introduce a general framework for models of cascade and contagion processes on networks, to identify their commonalities and differences. In particular, models of social and financial cascades, as well as the fiber bundle model, the voter model, and models of epidemic spreading are recovered...
