An Economic Analysis of Scrappage
分析鼓励老旧高污染车辆报废的政策（如1992年布什总统支持的旧车换现金计划）的收益与成本，并探讨其与其他政策（如改进的检测与维护）的互动，最后以洛杉矶为例模拟合理的项目设计参数。
This article examines the impact of policies aimed at encouraging the retirement of older, high-polluting vehicles, such as the cash for clunkers policy endorsed by President George Bush in 1992. The analysis assesses the likely benefits and costs of vehicle scrappage programs. I also address the interaction of a scrappage program with other ongoing policies, such as improved inspection and maintenance. Finally, the simulation for Los Angeles suggests plausible design values for a scrappage program.
