In North America and Europe, wheat is a very important commodity that has been at the heart of trade disputes and policy conflicts. This study uses a dynamic Almost Ideal Demand System (AIDS) to estimate demand elasticities for wheat differentiated by classes, for the United States and the European Union (EU). The results suggest that in the U.S. market imported wheat is more price responsive than domestic wheat. In the EU, however, price responsiveness varies according to the quality of wheat rather than its national origin.
