Cheap No more: Rising incomes in Asia and ethanol subsidies in America have put an end to a long era of falling food prices

December 6, 2007.  "Cheap No more: Rising incomes in Asia and ethanol subsidies in America have put an end to a long era of falling food prices," The Economist. Cites data, though unfortunately without attribution:
"America's ethanol programme is a product of government subsidies. There are more than 200 different kinds, as well as a 54 cents-a-gallon tariff on imported ethanol. That keeps out greener Brazilian ethanol, which is made from sugar rather than maize. Federal subsidies alone cost $7 billion a year (equal to around $1.90 a gallon)."
