Evidences show that IGAD member countries are the most political unstable countires in the world. Onrnthe other hand lietratures on the subject reveal that youth unemployment contributes the most towards thernpolitcal instabilty across the world. Nonethlesless, investigation on the effect of youth unemployment onrnpoltitical instabilty partcilauly in IGAD member countries is very scanty. Thus, the objecive of the currentrnstudy is to investigate the effect of youth unemplyment on poltical instability in IAGD member countries.rnFor this purpose the neccessary secondar data is collected from ICRG, WDI and ILO on five selectedrnIGAD member counrties. To find out the effect of youth unmployment on politcal instabilty; fixed effectrnmodel, instrumental varibale fixed effect model and one step system GMM estmaition on daynamic panelrndata have been employed. The analysis result revealed that there is a significant effect of youthrnunemployment on political instability and we support the hypothesis that youth unemployment causesrnpolitical instability in IGAD member countries. This paper also examined how other social and economicrnfactors can affect political instability. Our results suggest that political instability occurs particularly inrncountries where youth unemployment, as well as inflation, ethnic tensions and government instability, arernhigh. This region specifically needs a sound youth employment policy not only for the sake of youths, butrnalso for the relief of government reducing the burden of controlling continuous internal instabilities.rnMoreover, in region-wise the IGAD countries better to have common youth employment creation policiesrnso that they can manage the internal conflicts arises here and then
