 note = {https://www.grips.ac.jp/list/facultyinfo/tone_kaoru/, This paper, first, points out the shortcomings of the cost efficiency evaluations in DEA models, and then propose a new approach to circumvent this problem. Using this new approach, which is based on cost-production correspondence, we propose a new scheme for measuring cost elasticity of production and compare the results with those in the traditional model. Thus, this paper gives evidence on irrationality latent in the traditional approach, focusing on the cost vs. production elasticity issue. Finally, a case study on Life Insurance Corporation of India is presented to illustrate the potential application of this new scheme to elsewhere in the economy., Research supported by Grant-in-Aid for Scientific Research (C) Japan Society for the Promotion of Science},
