    Electricity sector reform in developing countries: an econometric assessment of the effects of privatisation, competition and regulation
    (Springer, 2008-04) Zhang, Yin-Fang; Parker, David; Kirkpatrick, Colin
    Over the last two decades electricity sectors in both developed and developing countries have been subject to restructuring to introduce private capital and increase competition. Although the effects of such reforms in a number of the developed economies are now well documented, apart from a few case studies the experience of developing countries is much less well researched. This paper provides an econometric assessment of the effects of privatisation, competition and regulation on the performance of the electricity generation industry using panel data for 36 developing and transitional countries, over the period 1985 to 2003. The study identifies the impact of these reforms on generating capacity, electricity generated, labour productivity in the generating sector and capacity utilisation. The main conclusions are that on their own privatisation and regulation do not lead to obvious gains in economic performance, though there are some positive interaction effects. By contrast, introducing competition does seem to be effective in stimulating performance improvements.

    An empirical analysis of state and private-sector provision of water services in Africa
    (Oxford University Press, 2006) Kirkpatrick, Colin; Parker, David; Zhang, Yin-Fang
    Under pressure from donor agencies and international financial institutions such as the World Bank, some developing countries have experimented with the privatization of water services. This article reviews the econometric evidence on the effects of water privatization in developing economies and presents new results using statistical data envelopment analysis and stochastic cost frontier techniques and data from Africa. The analysis fails to show evidence of better performance by private utilities than by state-owned utilities. Among the reasons why water privatization could prove problematic in lower-income economies are the technology of water provision and the nature of the product, transaction costs, and regulatory weaknesses
