High world food prices after 2006 concerned governments across the globe. Among various contributing factors, biofuels have received wide attention in recent years with more and more studies analyzing the implication of biofuel policies on global food supply and demand conditions. Relying on a model based upon U.S. biofuel policies, this paper studies the price links between crop and energy commodities induced by biofuel production, and simulates commodity price changes due to market and policy shifts. Results suggest price links exist between crop and energy commodities but more accurate measurement of commodity price changes induced by different market conditions will require the construction of a more detailed structural model.
