The Rotterdam model is used to estimate U.S. source-differentiated meat demand. Price and expenditure elasticities indicate that U.S. grain-fed beef and U.S. pork have a competitive advantage in the U.S. beef and pork markets, respectively. Expenditure elasticities reveal that beef from Canada has the most to gain from an expansion in U.S. meat expenditures, followed by ROW pork, U.S. grain-fed beef, and U.S. poultry. BSE outbreaks in Canada and the United States are shown to have small impacts on meat demand, while seasonality is found to have a significant effect in determining U.S. meat consumption patterns.
