In this study an import demand model (differential production model) is presented that is used in estimating the demand for source and product differentiated goods simultaneously. Unlike the traditional import demand models, this model can account for changes in relative group expenditures....

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...

This study examines the dynamic effects of grain prices and energy prices on catfish feed prices and the price of food-sized catfish at the farm level. Using the autoregressive distributed lag model and bounds testing procedure, a long-run relationship between feed and farm prices and their...

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...

In this study, we estimated catfish feed and farm price reduced form equations. Of particular importance was the impact of the recent increase in grain prices induced by ethanol production on feed cost and farm prices. This relationship was examined using an autoregressive distributed lag (ARDL)...

This study examined Nile perch demand in the Netherlands and assessed the importance of country of origin as a determining factor. Import demand equations were estimated using the absolute price version of the Rotterdam model where Nile perch fillets were differentiated by product form (chilled...
