Scientists flag global food pricing too hot to ignore

Sep 27, 2011
Food prices and model simulations - The FAO Food Price Index (blue solid line) [1], the ethanol supply and demand model (blue dashed line), where dominant supply shocks are due to the conversion of corn to ethanol so that price changes are proportional to ethanol production (see Appendix C) and the results of the speculator and ethanol model (red dotted line), that adds speculator trend following and switching between investment markets, including commodities, equities and bonds (see Appendices D and E).

A paper on the surge in world food prices is calling on private and public policy makers to recognize the serious impact that price spikes in food bring to the world’s most vulnerable populations.

The paper, “The Food Crises: A Quantitative Model of Food Prices Including Speculators and Ethanol Conversion,” was prepared by the New England Complex Systems Institute in a study partly funded by the U.S. Army.

The surge in has been frequently linked to numerous factors, while this study maintains two specific reasons account for the price increases. The authors slam and analyze the two culprits—speculators playing in the commodities markets and corn-to-ethanol conversion.

The authors refer to “since-debunked claims of the role of ethanol conversion in energy security and the environment.” They say a significant decrease in the conversion of corn to ethanol is warranted.

Using direct tests and statistical analysis, the paper pinpoints what is going on in global food pricing today. The authors discuss the motivations, techniques, and impact of commodity speculation, weather, development, and additional factors that are rounding out the pricing puzzle—exchange rates and energy costs.

The authors are Marco Lagi, Karla Bertrand, Yavni Bar-Yam, and Yaneer Bar-Yam. “The immediate implications of our analysis are policy recommendations for changes in regulations of commodity markets and production,” the authors state.
