英文文献：Acreage Response Estimation Through a Systems Approach
英文文献作者：McKinzie, Lance,Binkley, James,Gardiner, Walt
英文文献摘要：
A simple theoretical model is developed to show the advantages of a multi-equation approach to acreage response estimation. These principally involve the elimination of concern with land costs and the estimation of substitution relations among crops and effects from land expansion. The model is applied to the Midwest.
