Abstract
The objective of this paper was to verify the market power of the Argentinean, Brazilian and American exports of soymeal to the European Union, the main consumer market of this commodity. For that, the article is based on the methodology of residual demand. Using the methods Seemingly Unrelated Regression (SUR), Two-Stage Least Squares (2SLS) and Three-Stage Least Squares (3SLS), the results indicated that, though this segment is concentrated by Argentina, Brazil and the United States, none of these countries presented market power for soymeal exports. In other words, they are not able to change soymeal prices without to decrease the exports
