Abstract
Most modern economic studies agree that domestic and foreign savings are the basis for economic growth and development in developed or developing countries. Achieving the economic stability requires sufficient financial resources to finance productive investment and contribute to raising the rate of growth. The research deals with the problem of increasing capital flows internationally across countries, because of its positive effects on the economy as it enables decision makers to allocate resources more efficiently, and to give more scope to manage risks and respond to external shocks. On the other hand, recent opinions have emerged against it, indicating that the increase in the movement of foreign capital may increase the possibility of sudden repercussions in capital flows that destabilize economies and cause financial crises, for example, the Asian crisis in 1997, and the Turkish crisis in 2002 and the global crisis 2008. The research aims to analyze and measure the possibility of mobilizing capital to solve the puzzle of (Feldstein and Horioka, 1980), and to uncover the main challenges facing Arab countries. The analysis covered eight Arab economies, namely: Oman, Morocco, Jordan, Saudi Arabia, Egypt, Bahrain, Tunisia, Sudan, using panel data models for the period 1980-2018 and adopting the Generalized Placement Systems SYSGMM (Arellano and Bover, 1995). The research reached results consistent with the original FH hypothesis, (lower S-I gap with higher capital inflow). And capital mobility causes improvement in economic growth.
