Purpose.

 Methodology / approach. In we used multiple regression techniques to explore a dynamic panel data model based one-step system Generalized Method Moments (System-GMM). Proposed Arellano and Bover further developed Blundell Bond, System-GMM estimator was preferred over other because its efficiency eliminating simultaneous biases that are associated with estimations. Specifically, two-step our estimation due optimal weighting matrices.
 Results. The discovered although interactions between amplify positive set explanatory variables an extent, Africa is insignificant. also discovers net effects interactive terms developing slightly lower than least-developed countries. weighted average index under abysmal 44.54%, indicating moderate insecurity Africa.
