Derived Demand and Distributive Shares in a Multifactor Multisector Model
指出，在宏观层面研究要素派生需求和国民收入分配份额时，常用的总量生产函数方法要求各部门要素密集度完全相同，这一条件过于严格，不适用于大多数实际情况。
Most studies on the derived demand for factor inputs at the aggregate, nationwide level, and on the behavior of distributive shares in national income, form an analytical framework at the aggregate level which is parallel with the one at the industry level, by defining an aggregate production function for the economy as a whole. Unfortunately, the conditions for intersectoral aggregation are extremely restrictive and such an aggregate production function will be consistent with the sectoral technologies if and only if factor intensities are identical across sectors.' For most practical purposes, these conditions must be considered inappropriate.
