英文文献摘要：
The use of agricultural decoupled support has increased as World Trade Organization (WTO) member nations implement less trade distortive policies. However, the true production effects of these policies are still unclear. We show how the exclusion restrictions of U.S. direct payments, namely, the fruit and vegetable restriction and the requirement of keeping land in good agricultural use, cause the decoupled payment to become fully coupled over time as relative profits adjust. Theoretically, decoupled payments can be more trade distorting than an equivalent (same level of taxpayer expenditure) fully coupled subsidy.

随着世界贸易组织(WTO)成员国减少实施扭曲贸易的政策，农业脱钩支持的使用有所增加。然而，这些政策的真正生产效果仍不清楚。我们展示了美国直接支付的排除限制，即水果和蔬菜的限制以及保持土地在良好农业用途的要求，是如何随着相对利润的调整，使脱钩支付随着时间的推移而完全耦合的。从理论上讲，脱钩的支付比同等(纳税人相同水平的支出)的完全耦合补贴更能扭曲贸易。
