The results of single and multicommodity models are compared to evaluate the importance of multicommodity modeling in policy analysis. The analysis was conducted using wheat, feed grains, and soybean supply and demand models, which incorporate trade and price transmission relationships between major trading regions. Results of an exogenous yield stock indicate that price (export) impacts are generally higher (lower), and implied U.S. export elasticities are lower in cross-commodity than in single-commodity analysis. Trade liberalization impacts are generally, but not always, similar in direction in single and cross-commodity analyses, although magnitudes of impacts differ.
