The Feldstein–Horioka puzzle in African countries: A panel cointegration analysis

Abstract

This paper investigates the Feldstein–Horioka coefficients for 37 African countries using the recently developed Pooled Mean Group (PMG), Fully Modified OLS (FMOLS), and Dynamic OLS (DOLS) panel cointegration techniques. The empirical findings reported in this paper reveal that savings and investment are non-stationary and cointegrated series. The estimated coefficients using FMOLS, DOLS, and PMG are 0.38, 0.58, and 0.36, respectively, for the sample as a whole for the period from 1970 to 2006. These results confirm previous studies' findings that capital was relatively mobile in African countries compared to OECD countries. In addition, our study shows that there are marked differences in savings retention coefficients for different country groups in Africa (CFA franc zone and non-CFA franc zone countries, oil-producing and non-oil-producing countries, civil law and common law countries). These results have some policy implications.
