The impact of domestic and import prices on U.S. lamb imports: A production system approach. Agricultural and Resource Economics Review 36:293–303

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 respon-sive to domestic and import prices, while the direct opposite is the case for frozen lamb im-ports. 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 respon-sive to import prices while frozen imports became more responsive to import prices
