In late 2006 and early 2007, orange crops in Florida were smaller than expected, and the crop in California was put in a deep freeze by an Arctic cold front. As a result, the production of oranges was severely reduced. In addition, in early 2007, President George W.

He proposed an increase in ethanol produced from corn and the stalks and leaves from corn and other grasses. What is the likely impact of these two events on food prices in the United States?
