text: I may comment further on these reports in a future post. In the meantime, Iwill simply observe that if Babcock is correct, and U.S. biofuel policies have only a small influence on food prices because ???a large expansion in US ethanol production would have occurred even if the subsidies and mandates had not been in place,?? then U.S. taxpayers get little or no energy-security bang for billions of biofuel bucks.
