New Zealand is the only country to date to have implemented forced ownership unbundling of electricity distribution from the rest of the electricity supply industry (in 1998). This paper examines the impact of this policy on electricity prices, quality of service and costs. We find that...

The literature shows that for most UK industries privatization might be necessary but is not sufficient to produce economic benefits. Often prior changes in management or later changes in market structure and regulation have larger impacts than privatization itself. We ask what changes around...

Incentive regulation and efficiency analysis of network utilities often need to take the effect of important external factors, such as the weather conditions, into account. This paper presents a method for estimating the effect of weather conditions on the costs of electricity distribution...

This paper discusses whether a new paradigm is necessary for independent economic regulation of electricity (and closely associated natural gas) systems. We begin by summarising the nature of the traditional model of electricity reform and the place of economic regulation within it. Next we...

The Dutch regulatory process for setting the first X-Factors in the electricity distribution sector has gone badly wrong. During two-and-a-half years four different X-Factors were published by the regulator. These X-Factors fluctuated wildly. We demonstrate that Dutch electricity consumers will...

Argentina was one of the first countries in the world to implement a comprehensive reform of its electricity sector in the recent period. Among developing countries only Chile has had a comparably comprehensive and successful reform. This paper traces the history of the Argentine reform, which...

This paper examines the course of the deregulation and privatisation of public enterprises in the UK since 1979. The UK privatisation programme has been the most significant in the OECD involving the transfer of ownership of over 7% of GDP from the public to the private sectors. We examine the...

In December 1990, the twelve regional electricity companies responsible for the distribution and supply of electricity in England and Wales were privatised. For the first few years following privatisation, real prices, profits and costs in the industry rose. Following two price control reviews,...

Chile was the first country in the world to implement a comprehensive reform of its electricity sector in the recent period. Among developing countries only Argentina has had a comparably comprehensive and successful reform. This paper traces the history of the Chilean reform, which began in...
