Abstract. In this paper, we study the non-linear relationship between total public debt and domestic investment, across a panel of 10 African economies from 1981 to 2010. Our analysis, based on a panel threshold approach proposed by Hansen (1999), confirms the significance of the nonlinear relationship between public debt and domestic investment. The results indicate that public debt lower than 47.31 percent of GDP is positively associated with domestic investment. However, once the debt exceeds this threshold, the relationship between public debt and investment becomes negative. Moreover, we find some evidence that at this level, public debt limits the government’s ability to undertake countercyclical policies.
