We employ a nine-region electricity spatial and temporal price and allocation (e-STPA) model, à la Takayama and Judge (1971). Our main findings are: (1) currently, IPP entry is so small-scale as to bring about only marginal welfare gains while reallocating the industry's surplus from producers to consumers; and (2) expected future IPP entry could deliver significant welfare gains in all regions with substantial inter-regional transmission., JEL Classification Codes: L94, L51, R12, C61}, title = {A Spatial Equilibrium Analysis of Regulatory Reform in Japan's Electric Power Industry} }
