The elasticity of substitution and market share models are analyzed and applied to examine the issues of product differentiation and market rigidities in the U.S. exports of wheat, corn and soybeans. The hypothesis of inverse relationship between relative quantities exported by the United States and competing countries and their corresponding relative export prices is confirmed in the two models, for different commodities and under different specifications. Lagged quantity effects are also confirmed in the two models, for different commodities and under different specifications, indicating that some market rigidities exist in international markets. Estimation of the elasticity of substitution model using OLS, 2SLS, SUR and 3SLS procedures suggests that the importing countries with greatest price responsiveness are the Soviet Union and Egypt in the wheat market and Egypt, Taiwan and Mexico in the corn market. Price responsiveness also varies across exporting countries and the different estimation procedures suggest that higher competition prevails among the U.S./ROW and U.S./Argentina exports in the wheat and corn markets. Average estimates of the elasticities of substitution are calculated from all importing countries and values of -4.62 and -5.93 were obtained for wheat and corn, respectively. This result suggests that it is not unrealistic to assume an elasticity of substitution of -3.0 in applications of Armington model to analyze wheat trade flows. |
