PRODUCTIVITY IN SWEDISH ELECTRICITY RETAIL DISTRIBUTION

This paper examines productivity growth in electricity retail distribution in Sweden in a multiple output-multiple input framework. The approach used is nonparametric Data Envelopment Analysis (DEA). Productivity is measured by means of the Malmquist index. Productivity comparisons are made between different types of ownership and between different service areas. The study indicates a high rate of productivity growth, due to economies of density, when measured over a period of 17 years. The results show no significant differences in productivity growth between different types of ownership or economic organization.
