A Sector Analysis of Alternative Income Support and Soil Conservation Policies
用一个全国性跨区域模型分析不同政策能否同时提高农场收入和减少土壤侵蚀，发现保护导向的土地休耕政策能实现收入增长并大幅减少侵蚀、化学品使用和政府成本。
Abstract For nearly five decades Congress has attempted to legislate both higher farm incomes and soil conservation. A national, interregional, demand‐endogenous, separable programming model is used to analyze the potential of alternative policies to achieve simultaneously the dual goals of increased farm income and reduced soil erosion. The analysis indicates that a conservation‐oriented land retirement policy can be designed to achieve an increase in net farm income equivalent to a traditional general land retirement policy, while simultaneously achieving significant reductions in gross soil erosion, chemical input use, and direct government program costs.
