Import tariffs, domestic distortions and ‘market linkages’: 1 Rebalancing EU cereal protection?
用一个两国三商品的一般均衡模型证明，进口品与出口品互补以及国内存在出口补贴时，进口关税更可能降低福利；并分析了欧盟对玉米麸饲料和大豆粕的进口关税的福利效应，发现CAP改革改变了市场关联，使对玉米麸饲料的关税可能提高福利，但对大豆粕则不然。
This paper demonstrates that, in a two-country three-good general equilibrium model, both complementarity between import and export goods and the presence of an export subsidy at home make an import tariff more likely to be welfare-decreasing for the active country. The welfare efficiency of EU import tariffs on corn gluten feed (CGF) or soymeal is then examined, emphasising the role of the CAP reform in altering market linkages by potentially making grains and these ingredients more complementary in feed rations. An import tariff on CGF would be welfare-enhancing for the EU, whereas the CAP reform tends to rule out the welfare efficiency of a tariff on soymeal.
