Decomposition of Cost Efficiency and its Application to Japan-US Electric Utilities Comparisons TONE, Kaoru TSUTSUI, Miki cost efficiency technical efficiency price efficiency allocative efficiency DEA https://www.grips.ac.jp/list/facultyinfo/tone_kaoru/ This paper presents a new formula for decomposing cost efficiency into technical, price, and allocative efficiencies in an environment marked by the fact that unit input prices differ among certain enterprises. We employed this formula for comparing cost efficiency between Japan-US electric power companies and found a significant difference in the price-based efficiency between the two countries; however, negligible differences were found in the technical and allocative efficiencies.
