Abstract: In this study, we apply the Panel Stationary test with both sharp and smooth breaks to test the validity of long-run purchasing power parity (PPP) for 20 African countries using quarterly data over the period 1971I-2012IV. Empirical results of Panel stationary tests with both sharp and smooth breaks indicate that PPP holds true for 10 out of these 20 African countries (i.e., Burkina Faso, Cameroon, Ghana, Kenya, Niger, Senegal, Seychelles, South Africa, Tanzania and Togo) studied.
