Dynamic demand systems have been employed in a number of studies to account for habit formation and inventory adjustments in demand. Few studies have attempted to provide a theoretical foundation for the dynamic demand structures employed. Recently, Bushehri (2003) showed how a generalized...

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...

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...

We estimated a wholesale demand system for beef, pork, lamb, chicken, and turkey using quarterly U.S. data and a dynamic, CBS system (Keller and Van Driel). The CBS system is a differential system, which means that it might be more appropriately applied in those situations where the data have...

Estimates of price and scale demand elasticities for lamb and mutton consumed in the United States are derived. The U.S. lamb and mutton consumption comprises primarily of domestic production, and imports from two countries-Australia and New Zealand. The Netherlands Central Bureau of Statistics...

The non-linear Inverse Almost Ideal Demand System is used in estimating the impact of exchange rates on source-differentiated import demand for beef in the USA. We estimate scale, own and cross-price flexibilities for six major beef suppliers and the rest of the world, incorporating exchange...

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...

The generalized dynamic Rotterdam model was used in estimating U.S. demand for disaggregated catfish. The overall goal was to examine habit persistence in consumption and to determine the adjustment process in demand. Results indicated that it took up to 1 month for catfish-product demand to...

Seasonal unit-root testing and seasonal cointegration methods are employed to investigate the price transmission in U.S. shrimp markets. ARIMA and Vector Error Correction Models (VECM) are used to identify the effect of catastrophic events on individual price series in one region and the...

Farm, wholesale and retail price relationships for U.S. hogs are analyzed. Price transmission estimates indicate partial adjustment in each market category when price changes in any other market. This implies imperfect price transmission between the market levels. Tests of Granger no-causality...
