Feldstein-Horioka Puzzle and International Capital Mobility in High Income Countries: A Pool Mean Group Approach

Abstract

This paper reexamines the status of international capital mobility under the Feldstein-Horioka (1980) hypothesis by comparing the results from the OECD and non-OECD high income categories. Data on savings and investment ratios of 21 OECD and 17 non-OECD countries were analyzed using the dynamic heterogeneous panel estimators of Pooled Mean Group (PMG), Mean Group (MG) and Dynamic Fixed Effects (DFE). Based on the series of Hausman post-estimation test, result from the PMG is upheld. The saving-retention coefficient, showing the level of international capital mobility, reads 0.89, 0.93 and 0.16 for the high-income group, OECD category and non-OECD category respectively. This suggests lower capital mobility in high-income as a whole and OECD countries, and higher capital mobility in the non-OECD countries. The contradictory findings confirmed that the Feldstein-Horioka saving-retention coefficient is unlikely, a viable option of measuring cross-border capital mobility. Further researches therefore need to re-observe the qualification of saving-retention coefficient in explaining international capital mobility.
