The ‘oilseed tax’ and U.S. soyabean exports to the enlarged European Community
研究通过区分产品来源的模型，评估油籽税对美国向扩大后的欧共体出口大豆的潜在影响，发现扩大欧共体会增加美国大豆出口，但油籽税会显著减少出口。
A model differentiating products by origin was utilised to evaluate the potential impact that the imposition of a tax on oilseed crushing would have on U.S. soya-bean exports to the enlarged EC. Simulation of the enlargement results in a significant increase of U.S. and total soyabean exports to the new EC members, but the imposition of an oilseed tax would cause a substantial decline in U.S. and total soyabean exports to the enlarged EC. The interaction of the proposed tax with the increase in corn tariffs would result in a moderate increase of soyabean imports into Spain and Portugal.
