CHAMPAIGN, Ill. — An ethanol-fueled spike in grain prices will likely hold, yielding the first sustained increase for corn, wheat and soybean prices in more than three decades, according to new research by two University of Illinois farm economists.
Corn, an ethanol ingredient that has driven the recent price surge, could average $4.60 a bushel in Illinois, nearly double the average $2.42 a bushel from 1973 to 2006, said Darrel Good and Scott Irwin, professors of agriculture and consumer economics.
