Abstract

One of the main expectations from power market reform has been a reduction in both price-cost margins and cross-subsidy levels between industrial and residential consumers. This paper focuses on this issue by looking at the impact of the electricity industry reforms on residential and industrial electricity price-cost margins and their effect on cross-subsidy levels between consumer groups. Using panel data for 63 developed and developing countries covering the period 1982-2009, empirical models are developed and analyzed. The research findings suggest that there is no uniform pattern for the impact of reform process as a whole on price-cost margins and cross-subsidy levels. Each individual reform step has different impact on price-cost margins and cross-subsidy levels for each consumer and country group. Our findings imply that reform steps have different impacts in different countries, which supports the idea reform prescription for a specific country cannot easily and successfully be transferred to another one. So, transferring the formal and economic structure of a successful power market in a developed country to developing countries is not a sufficient condition for good economic performance of the electricity industries in developing countries. Furthermore, the study suggests that power consumption, income level and country-specific features constitute other important determinants of electricity price-cost margins and cross-subsidy levels.
