Opium in Afghanistan: Prospects for the Success of Source Country Drug Control Policies
评估了来源国毒品管制政策减少阿富汗鸦片产量的潜力，发现替代发展项目效果有限（减产不到6.5%），而大幅增加作物铲除才能实现适度减产（3%至19.4%）。
Recent estimates suggest that in 2007, Afghan opiate production accounted for about 93 percent of the world’s total. This article presents a framework for estimating the potential for source country drug control policies to reduce this production. It contains a first pass at estimating the potential for policy to shift the supply of opium upward, as well as a range of supply and demand elasticities. The estimates suggest that meager reductions in production can be expected through alternative development programs alone (reductions are less than 6.5 percent in all but one of the specifications presented). They also suggest that substantial increases in crop eradication would be needed to achieve even moderate reductions in production (reductions range from 3.0 percent to 19.4 percent for various specifications). The results also imply that, all else being equal, the cessation of crop eradication would result in only modest increases in opiate production (with estimates ranging from 1.6 percent to 9.6 percent).
