Estimation of Multicrop Production Functions
比较了可分离性与非联合性在多作物生产函数估计中的适用性，认为非联合性更合理，并提出了在投入分配不可观测情况下的估计方法。
Abstract This paper considers whether separability or nonjointness is the better approach for attaining tractability for multicrop production function estimation. Characteristics of agricultural production associated with allocated inputs, physical constraints, and output determination imply sufficient nonjointness for estimation, whereas separability is less plausible. The paper also addresses estimation of production functions with allocated inputs where allocations are not observed and demonstrates a proposed approach by way of example.
