This article investigated income per capita convergence in the Southern African Development Community (SADC) over the period 1980-2017 in a non-linear time-varying coeﬃcients framework. The ﬁndings of the study suggested no overall income convergence in the SADC region, but evidence supporting the existence of convergence clubs was found indicating that the SADC comprises ﬁve convergence clusters, each converging to its own steady-state equilibrium. These ﬁndings suggest that, to promote convergence in the region, policies that explicitly target ’low-income’ countries are warranted.
