Recently developed panel co-integration techniques are applied to data for six African countries to test the FeldsteinHorioka approach to measuring capital mobility. The results suggest three conclusions: savings and investment in panel data are non-stationary series and they are co-integrated; capital was relatively mobile in the African countries during 19702000, with estimated savingsretention ratios of 0.73 (FMOLS), 0.45 (DOLS), 0.51 (DOLS with heterogeneity) and 0.39 (DOLS with cross-sectional dependence effects); and there was a marked drop in the savingsretention ratio from 197085 to 19862000. The results could be interpreted as indicating that capital mobility in African countries has increased, reflecting the implementation of market-orientated reforms, including the privatisation and rationalisation of the public sector, and the partial liberalisation of their exchange rate regimes and financial systems.
