Conversable Economist: The Rise of Remittances
"Here's a pattern showing the rise in remittances over time compared to some other international financial flows. Back in 1990, international remittances were lower than official development assistance (ODA). Flows of foreign direct investment (FDI) to developing countries were also smaller than ODA, as were flows of private debt and portfolio equity to developing countries. (The FDI flows to developing countries show here exclude China.) Remittances have been larger than development assistance for some years now, and the gap is growing. Perhaps more surprising, remittances also outstripped debt and portfolio equity flows to developing countries in recent years. The flows of remittances also look quite stable compared to other private-sector capital flows."
