This paper addresses the question of whether the export demand for soybeans and soybean products changed structurally over the 1950 to 1992 period as the U.S. agricultural sector became more integrated with the rest of the world economy. The results suggest that export demands were stable for soybeans, soybean meal and soybean oil over the sample period. Moreover, it is possible to infer conclusively that the long-run soybean and soybean product export price elasticities were in the elastic range. The implications include that for each one percent reduction in the price of soybeans, soybean meal and/or soybean oil brought about through a government program, exports increased by more than one percent, leading to a reduction in the variability of soybean and...

Actual Media Reports on GM Foods and Chinese Consumers' Willingness to Pay for GM Soybean Oil

A Comparative Analysis of the Development of the United States and European Union Biodiesel Industries

Hu, Wuyang; Zhong, Funing; Ding, Yulian.

Information has been proven to have significant impacts on consumers' behavior and willingness to pay (WTP). In this study, information on GM soybean oil is given in the form of real-life cases involving GM food. These cases recorded from actual media reports. Using a hybrid of the double-bounded and payment care elicitation approaches, Chinese consumers' WTP for soybean oil is examined both before and after these cases are presented to them. Results indicate that media reports on positive cases do not increase consumers' WTP significantly, while reports on negative cases drastically lower their WTP.

Hedging Break-Even Biodiesel Production Costs Using Soybean Oil Futures

Carriquiry, Miguel A..

Worldwide production of biodiesel is growing at a rapid pace. Arguably, the European Union (EU) is the global leader in biodiesel production, but the United States has recently expanded its production. The growth of the biodiesel industry in both regions has been fueled by a series of government-provided financial incentives. However, the timing of the growth and incentive provisions, the nature of the main incentives, and the market conditions differ across regions. This article provides a comparative analysis of the EU and U.S. biodiesel industries, highlighting market and policy aspects that are leading to a rapid but distinct growth.

The effectiveness of hedging volatile input prices for biodiesel producers is examined over one- to eight-week time horizons. Results reveal that hedging break-even soybean costs with soybean oil futures offers significant reductions in input price risk. The degree of risk reduction is dependent upon type of hedge, naïve or risk-minimizing, and upon time horizon. In contrast, cross-hedging break-even poultry fat costs with soybean oil futures failed to reduce input price risk.
