Before revision:  In this paper , we employ two networkanalysis methods on the international investment network derived from the IMF Coordinated Portfolio Investment Survey (CPIS) . Via the "error and attack" methodology [1], we show that the CPIS network is of the " robust- yet-fragile " type, similar to a wide variety of evolved networks 1, 2 . In particular, the network is robust to random shocks but very fragile when key financial centers (e. g., the United States and the Cayman Islands) are affected.
After revision:  In this paper , we employ two networkanalysis methods on the international investment network derived from the IMF Coordinated Portfolio Investment Survey (CPIS) , in two ways. First, through an adaptation of the "error and attack" methodology [1], we show that the CPIS network is of the " robust- yet-fragile " type, similar to a wide variety of evolved networks 1, 2 . In particular, the network is robust to random shocks but very fragile when key financial centers (e. g., the United States and the Cayman Islands) are affected.
