Welfare Effects of the National Pseudorabies Eradication Program
评估美国伪狂犬病根除计划的市场与分配效应，发现该计划总体经济有效，但不同地区养猪户的福利变化存在差异。
Abstract A welfare methodology is adapted to evaluate market and distributional effects of a completed pseudorabies eradication effort in the U.S. The model predicts small market effects from pseudorabies eradication. Welfare analysis suggests that, in states generating relatively large hog numbers, producers will experience a net gain from eradication in all scenarios considered, yet in smaller hog producing areas individual hog operations may lose producer surplus. Consumer surplus changes vary by scenario but are always positive. In general, the national pseudorabies eradication program is shown to be economically efficient.
