The Measurement of Productive Efficiency: A Reconsideration
推广了Farrell生产效率指数到非齐次生产技术,并保持其成本解释,回顾了前沿成本和生产函数估计模型,讨论了技术、配置和总体效率指数及单因素效率测度,并用电力发电数值例子说明。
The purpose of this paper is to generalize the Farrell indexes of productive efficiency to nonhomothetic production technologies, and at the same time maintain the cost interpretation of the Farrell measures. Since the generalized indexes rely heavily on recent developments in the estimation of frontier cost and production functions, several frontier models are reviewed. In addition to generalized indexes of technical, allocative, and overall productive efficiency, a variety of single-factor efficiency measures are discussed. The applicability of the proposed efficiency measures is illustrated with a numerical example of electric power generation.
