We provide a framework to study the formation of financial networks and investigate the interplay between banks …, creating insufficiently connected financial networks that are excessively prone to contagious defaults. Finally, we show that … banks' private incentives may lead to the formation of financial networks that are overly susceptible to systemic meltdowns …
