Abstract: This study investigates the degree of convergence in military expenditure and security outcome for the eight regional economic communities (RECs) of Africa spanning 1995–2015. We utilise the methodology of the Phillips and Sul convergence test to each of the region’s military expenditure and security outcome. The results of this study suggest that the convergence club of military expenditure and security outcome cannot be generalised across the RECs of African countries, and likewise for the overall convergence of the regions. The nonconvergence of the full sample and the presence of the different subgroup convergence clubs for both variables imply that RECs of African countries are characterised by individual factors which in turn determine an idiosyncratic course of their own path for defence and security policies. The empirics further confirm that the regions appear to have chosen dissimilar paths for their defence and security measures. Considering the cross-border and multiple security challenges facing the continent, this study recommend that African RECs harmonise their defence and security policies in order to achieve a convergence for a concerted security threats facing the regions.
