We estimate the elasticity of substitution using two different production functions. The usual Constant Elasticity of Substitution (CES) production function and a Box-Cox production function for Japan (1890-1991), UK (1870-1991), and US (1890-1992; 1929-2000). The main results are that we find the...

This paper studied the United States import market for Chilean tablegrapes, with the objective of analyzing the competitiveness of Chile inthis market. Using the LA/AIDS model (Linear Approximation almost IdealDemand System), the import demand parameters were obtained for Chile,Mexico and the...

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....

This study has used a corrected likelihood ratio, with AIDS and Rotterdam demand models, to test separability in three separable (A, B, C) wheat import demand structures on the French common wheat market. It appears from the study that the three separable Rotterdam structures are accepted by the...

This report provides summaries of the papers and discussions atthe third Consortium on Trade Research held in Washington, D.C.,June 23-24, 1981. The cochairmen of the consortium wereT. Kelley White, Economic Research Service (ERS), George E.Rossmiller, Foreign Agricultural Service (FAS), and...

Cointegration analysis and an Error Correction Model are used to estimate aggregate seafood import demand functions for selected Caribbean countries. The results show that seafood import demand is price elastic. Exchange rate has a negative effect on seafood import quantity. Income and tourist...
