The time series data are drawn from various sources. The co-integration approach is applied in this study. From the empirics, it came out clearly that on hand, the foreign aid has an slightly positive effect on economic growth but a highly insignificant on the child mortality rate during this straining civil war; on the hand socio-political stability has a positively significant on child mortality rate but not on economic growth. We recommend that security, good governance and decentralised political governance are the prerequisite for the efficiency of foreign aid.application/pdfArticle
