The Economist covered this topic recently:


Just curious, have I missed "freakonomics" here tying higher food prices to biofuels?

I'm not sure how tight the connection is, but I think there is a contribution to prices from ethanol and oils policy. I'm more surprised that ordinary people seem to think this connection is outlandish. Flour is more expensive because of ethanol? "Get out."
