From the Economist:
“For workers from poor countries who venture abroad to earn a better living, sending money home to relatives can be hugely expensive. Such remittances have become an important source of income in many developing countries, dwarfing other inflows of capital from overseas such as foreign direct investment and multilateral aid. But if the money is being sent, say, from America to Venezuela, charges can amount to as much as 34% of the sum involved, according to Dilip Ratha of the World Bank.
“Why are the poor so badly served? The easy answer, that people who have little money do not make suitable clients for sophisticated financial services, is at most a half-truth. A better explanation, this survey will argue, is that the poor have been hurt by massive market and regulatory failure. Fortunately that failure can be, and increasingly is being, remedied.”
