Before revision:  Using loss-given-default dynamics [ 3 ], "extinction analysis" simulations show that interdependence increased from 2001 to 2007. Our simulations further indicate that default by a single relatively small country like Greece can be absorbed by the network, but that default in combination with defaults of other PIGS countries (Portugal, Ireland, and Spain) could lead to a massive extinction cascade in the global economy.
After revision:  Using loss-given-default dynamics [ 3 ], we model financial interdependence and potential cascading of financial distress through the network. Preliminary simulations indicate that default by a single relatively small country like Greece can be absorbed by the network, but that default in combination with defaults of other PIGS countries (Portugal, Ireland, and Spain) could lead to a massive extinction cascade in the global economy.
