Assumptions in the 1985 RCA: A Review
详细阐述了1985年RCA（区域商品分析）模型所需的基本假设，包括人口、国民生产总值、收入、技术变化、能源成本和资本可用性，并讨论了编程模型中的区域划分、作物部门、土地基础和投入成本假设。
The purpose of this paper is to elaborate on the basic assumptions that have been made or need to be made before the solutions for the 1985 RCA,\nAt the last Project Advisory Committee (PAC) meeting a paper put together by USDA's Basic Assumption Work Group (BAWG) was presented (APPENDIX A). This paper, written by BAWG, examines population levels, gross national product, disposable personal income, institutional and technical change, energy cost, and capital availability. A second paper handed out at the last meeting outlined some of the programming models' assumptions. Many of the points listed in this outline will be examined more completely in this working paper.\nThis paper will state the regions to be used in the programming model, the assumptions used in the creation of the crop sector, the land base, and input costs. It will examine technology and demands.
