PRODUCTION FUNCTIONS AND THE DISAGGREGATION OF LABOR INPUTS IN MANUFACTURING PLANTS*
研究质疑了区域模型中劳动投入同质性的假设，发现制造业工厂中非生产性劳动与生产性劳动不可完全分离，因此区域模型需考虑这一差异才能得到可靠结果。
ABSTRACT. This paper investigates the assumption of homogeneous labor inputs underlying the production functions in many regional models. The results indicate that nonproduction and production labor within manufacturing plants are not strongly separable, and the homogeneous labor assumption is not therefore appropriate. Hence, regional models need to take this into account in order to give reliable results. Differences between industries provide useful additional insights into their labor and capital relationships.
