Fire, Tractors, and Health in the Amazon: A Cost-Benefit Analysis of Fire Policy
研究评估了亚马逊西部阿克里州部分禁止农业火灾并补贴拖拉机的政策，发现五种延长禁令的方案能在补偿拖拉机使用的情况下同时改善呼吸健康和小农福利。
Pollution from agricultural fires is a global health issue that is particularly challenging where smallholders depend on burnings for subsistence. In Acre state, Western Amazon, a partial ban on fire, enforced with fines, is coupled with subsidized tractors. To evaluate this policy, a discrete choice experiment and contingent valuation were merged into a novel statistical variant of the Hicks-Kaldor test that is robust to preference heterogeneity. Among 27 ways to extend the ban, 5 could improve both respiratory health and smallholders’ welfare, when compensated with tractors that are available for longer hours and at the right time of the year.
