Abstract

Substitutability among United State exports and exports of various competing countries in the world agricultural market is investigated using an elasticity of substitution model (ES). The ES estimation uses OLS, 2SLS, SUR, 3SLS. Data for corn and wheat in nine import markets are used, considering the possibilities of lagged ajustment, correlation of errors across import markets and endogeneity of export prices.
