Agricultural Product Supplies and Input Demands: Regional Comparisons
估计了美国十个区域五种产出供给和四种投入需求方程，揭示了生产关系的区域多样性，并说明经济条件与政策变化对不同区域的影响不均。
Abstract Supply equations for five output groups and demand equations for four input groups in ten regions of the United States are estimated and evaluated. The econometric estimation is conducted for complete regional product supply and input demand systems subject to competitive theory. The results document the extreme diversity of production relationships within the United States. They clearly indicate the unequal effects of changes in economic conditions and government policies on major production regions.
