Our analysis has two notable features. First, we distinguish three sectors in this industry for analyses of deregulation in detail: power generation, transmission, and distribution. Second, we consider substitution among four energy commodities. Our numerical simulations show a potential for significant welfare improvements and substitution among energy sources from deregulation. Depending on whether dergulation abolishes monopoly rent or x-inefficiency, the effects of deregulation on factor markets would qulitatively differ., JEL Classification Codes: L94, L51, C68}, title = {The Deregulation of Japan's Electricity Industry} }
