As the linkage between domestic and foreign financial markets grows stronger, concerns have been raised about the inflow and outflow of foreign investment capital as a source of financial instability whenever the financial market becomes unstable. Considering that opening the capital market is not an option, it becomes essential to examine the determinants of foreign investment to maximize the benefits of foreign capital inflows and outflows for sound growth in the real sector as well as the financial sector. Accordingly, this study attempts to produce evidence-based policy implications by empirically analyzing the determinants of the inflow and outflow of foreign investment funds.
