Analysis of Profit-Linked Total-Factor Productivity Measurement Models at the Firm Level
比较了美国生产力中心的全要素模型和乙基公司的“盈利能力=生产率+价格回收”模型，分析两者在方法上的根本差异，帮助企业选择更合适的生产率测量方法。
The purpose of the paper is to present the results of a comparative analysis of two main-line productivity measurement procedures: the American Productivity Center's total factor model, and the Ethyl Corporation's “Profitability = Productivity + Price Recovery” model. Several fundamental differences between the two approaches are identified and analyzed. As demonstrated in the paper, differences such as the method of deflation can substantially affect the proper choice of the more appropriate procedure to use in a given corporate setting.
