On the measurement of aggregate production functions
以索洛1957年论文的测度方法为例，指出若技术变革符合中性和同质性假设，则测得的并非弯曲的生产函数，而是基期加权的产出恒等式，质疑了正统生产理论的实证相关性。
The present paper is addressed to a basic issue concerning the measurement of aggregate production functions using the method of measurement employed in Robert Solow's 1957 paper as an illustration. The author finds that if technical change is appropriately accounted for so as to be consistent with the neutrali ty and homogeneity hypotheses, what would obtain, both analytically and empirically, is not a curved production function bu t an output identity with base-period weights. This suggests that the empirical relevance of the orthodox production theory is suspect. Copyright 1992 by Oxford University Press.
