An EC Feed Grain Spatial Equilibrium Model for Policy Analysis
构建了一个多商品价格内生的欧盟饲料谷物空间均衡模型，利用伪数据方法估计非可积饲料需求函数，并分析了三种欧盟政策调整（取消绿色汇率、降低支持价格、对进口谷物替代品征税）对价格和数量的短期与长期影响。
This paper presents a multicommodity price-endogenous spatial equilibrium model of the EC feed grain sector. The model incorporates nonintegrable feed grain demand functions which were estimated using a pseudodata approach based on a set of representative least-cost LP models of compound feed production in the EC. The price and quantity impacts of three "rebalancing " EC policies are investigated within a comparative statics frameworlc the abolition of the green rates or MCA system, a 10 % cut in support prices for EC grains, and a 10 % tax on the use of imported cereal substitutes. Both 'short-run ' (constant livestock output) and 'long-run ' (variable livestock output) results are reported at the EC level.- 1-
