In this paper we are primarily concerned with assessing the degree of capital mobility in sub‐Saharan Africa. Using the methodology as proposed by Feldstein and Horioka (1980)—later termed the “Feldstein‐Horioka puzzle”—we test the hypothesis of perfect capital mobility against the alternative of imperfect capital mobility. Following Vamvakidis and Wacziarg (1998) and Isaksson (2000), provision is made in our model to show the dependency of the lesserdeveloped countries on international finance and aid and how a more open economy contributes towards improving the level of capital movement in these countries. We also assess the change in the degree of capital mobility over the time period in an effort to see whether institutional and political changes have been successful. We show that, compared to the region, South Africa is, to a large extent, more developed and should therefore play a leading role in the “African Renaissance”. Stationary panel data estimation techniques are applied to a sample of 36 sub‐Saharan African countries over the time period 1980–2000. The benefits of using one‐way error component models are derived from simultaneously employing time and cross‐section dimensions of the data, resulting in a substantial increase in the degrees of freedom. The fixed and random effects models enable us to acknowledge country heterogeneity within the panel, making provision for differences across countries like capital control policies, financial and capital market structures and exchange rate regimes.
