The Impact of Domestic and Import Prices on U.S. Lamb Imports: A Production System Approach

As U.S. lamb imports increased relative to domestic production, and the relative share of chilled to frozen lamb imports increased, importers of chilled lamb have become less responsive to domestic and import prices, while the direct opposite is the case for frozen lamb imports. From 1990 to 2003, chilled lamb imports from Australia and New Zealand became less and less responsive to U.S. prices, and frozen imports became more responsive. Unconditional own-price elasticities also show that, over time, imports of chilled lamb became less responsive to import prices while frozen imports became more responsive to import prices.

Source-Based Preferences and U.S. Salmon Imports

Abstract This study examined U.S. demand for salmon imports differentiated by source (Canada, Chile, and the rest of the world [ROW]), product cut (fillets and other salmon products), and form (fresh and frozen). The Rotterdam model was used in estimation, and source-aggregation tests were performed to determine the significance of source differentiation in analysis. We also performed separability tests to determine if import preferences were source-wise dependent or source independent. Test results strongly reject source aggregation; however, source-wise dependence could not be rejected. Furthermore, source-aggregated demand was significantly more price-elastic when compared to source-wise dependent demand. Results show that import preferences are not homogeneous across exporting countries, and there is significant information loss when source differentiation is not considered.

Country of Origin Labeling: Evaluating the Impacts on U.S. and World Markets

A provision of the Food, Conservation, and Energy Act of 2008 requires country of origin labeling (COOL) for certain agricultural commodities. To comply with the law, producers, processors, and retailers face additional production costs associated with labeling, separating, and tracking commodities. Using estimated costs provided by the U.S. Department of Agricultures Agricultural Marketing Service (AMS), we simulate the impacts of mandatory COOL on U.S. and global agricultural markets using a global static general equilibrium model (STAGEM). The results show resource adjustments that lead to decreases in production, consumption, and trade flows. The results assume no demand premium for labeled commodities relative to unlabeled commodities.

The Impact of Catfish Imports on the U.S. Wholesale and Farm Sectors

The primary objective of this study was to assess the impact of catfish imports and tariffs on the U.S. catfish industry, with particular focus on the U.S. International Trade Commission ruling on Vietnam in 2003. Given the importance of Vietnam to the U.S. catfish market, it was assumed that catfish import prices would increase by 35 percent if the maximum tariff was imposed on catfish from Vietnam. With the tariff, domestic catfish prices at the wholesale level would increase by

Source-differentiated analysis of exchange rate effects on US beef imports

Estimates of price and scale elasticities for U.S. consumed shrimp are derived using aggregate shrimp data differentiated by source country. Own-price elasticities for all countries had the expected negative signs, were statistically significant, and inelastic. The scale elasticities for all countries were positive and statistically significant at the 1% level with only the United States and Ecuador having scale elasticities of less than one. For the most part, the compensated demand effects showed that most of the cross-price effects were positive. Our results also suggest that despite the countervailing duties imposed by the United States, shrimp demand was fairly stable.

Crops and Livestock Productivity Measures for Selected Countries

Citrus fruits make up 1/5 of all fresh fruit consumed in the United States. Given the increasing importance of imported citrus in the diet of American consumers, it is perhaps surprising that no import demand analysis of U.S. citrus has been conducted. Using quarterly U.S. import data for 6 citrus commodities, we employed a demand systems model and evaluated aspects of seasonality. The results suggest wide variations in price responses to different types of imported citrus. The average amplitude and phase shift suggest that all citrus fruits exhibit some seasonality in their imports, likely a result of peak harvesting schedules of exporters.
