The EEC's Wheat Price Policies and International Trade in Differentiated Products
分析欧共体小麦市场中进口与国内供应的不完全替代性、同时进出口现象，以及门槛价格与干预价格的不同影响。实证发现干预价格增加净出口，而门槛价格降低净出口，对研究农业贸易政策者有用。
Abstract Several features of the EC wheat market are analyzed including the imperfect substitutability between imports and domestic supplies, the simultaneous import and export of wheat, and the distinct impact of threshold versus intervention policy prices. In theory, the impact of EC price policies on wheat consumption and net trade are found to be indeterminate a priori. Empirical results show that intervention prices have a positive impact on EC net exports, while increases in threshold (import) prices have decreased EC net wheat exports. Competing wheat exporters would prefer the EC to lower the intervention price to world levels but maintain threshold prices.
