"Exporters monitor economic and political policies to the developing world, but the consequences of that have been to make developing countries far more sensitive to the constant fluctuations. Developing countries are not always allowed to support their farmers in the same way as the U.S. or Europe is. They're not allowed to have tariff barriers. They're forced, more or less, to shrink their social programs. The very poorest people have fewer and fewer entitlements. The consequence of this has been that there's been a chronic increase in the vulnerability of those economies to price shocks."
