摘要
The main purpose of this study is to examine the impacts of deregulation on technical efficiency and its changes over time for large-scale U.S. electric power utilities during the period from 1992 through 2000. We analyze the efficiency of three individual functions, i.e., generation, transmission/distribution, and general administration, and the deregulatory impacts on each of them. In order to implement the analysis, we estimate an input distance function by using a stochastic frontier analysis. The results indicate that there is a significant impact of deregulation on efficiency in the generation and general administration functions, while no effects are observed in the transmission/distribution function.
