It should be noted, however, that it is difficult, if not impossible, given available data, to identify mainstream capital market participation by diasporas. Investments made by diaspora members in conventional investment vehicles open to all investors are indistinguishable from other foreign investments. But governments and businesses in some countries of origin have created financial instruments especially designed to tap into the wealth of diaspora populations. While some are aimed at high-net- worth individuals, some are accessible to small-scale savers. Policymakers have not yet tapped the potential of devising reliable and investor-friendly mechanisms and instruments that allow migrants (and other small-scale savers).
