Effects of the EEC's Variable Import Levies
分析了欧共体对农产品使用的可变进口关税机制，关注其对世界市场的不稳定影响，以及如何捕获贸易限制的经济租金和出口国的补贴支付，并提供了相关统计数据。
The mechanics of variable import levies, as used by the EEC for agricultural products, are analyzed. Attention is paid to their destabilizing effects on world markets and to the way in which they can capture not only economic rent associated with trade restrictions but also the subsidy payments of exporting countries. Statistics are provided showing the importance of variable levies in the EEC, their ad valorem incidence, and variation, and a rough estimate is made of their depressing effect on world prices.
