Book Description
The paper undertakes a dynamic analysis for service quality in the electricity distribution in Brazil between 2010 and 2014 based on Malmquist indexes constructed upon Data Envelopment Analysis (DEA) distance functions. The motivation for the less usual consideration of efficiency frontiers for service quality, that does not rely on traditional inputs and outputs but rather on quality indicators, builds on previous static applications in the context of telecommunications. The analysis considers undesirable technical indicators for quality as inputs and desirable consumer satisfaction indicators for quality as outputs in the efficiency frontier analysis. The bootstrap-corrected Malmquist indexes indicated service quality deterioration in 38.1 per cent, quality stagnation in 40.5 per cent and quality improvement only in 21.4 per cent of the cases. When one decomposes the Malmquist index, the evidence does not suggest relevant frontier shifts and indicates a dominant role for the catch-up effect. Finally, Malmquist indexes are regressed against variables that may portray heterogeneities, such as firm size, service area, density, ownership and regional dummies in terms of a well-known two-stage procedure. The mostly weak significance results reinforce the plausibility of the initial analysis.

Book Description
The paper undertakes a dynamic analysis for service quality in the electricity distribution in Brazil between 2010 and 2014 based on Malmquist indexes constructed upon Data Envelopment Analysis (DEA) distance functions. The motivation for the less usual consideration of efficiency frontiers for service-quality builds on previous static applications in the context of telecommunications as given by Façanha and Resende (2004), Resende and Façanha (2005) and Resende and Tupper (2009). The analysis treats undesirable technical indicators as inputs and desirable consumer satisfaction indicators as outputs. The bootstrap- corrected Malmquist indexes indicated that service quality is an important concern as the evidence respectively indicates quality deterioration in 38.1%, quality stagnation in 40.5% and quality improvement only in 21.4% of the cases. When one decomposes the Malmquist index, the evidence does not suggest relevant frontier shifts and indicates a dominant role for the catch-up effect.

Book Description
The goal of this article is to demonstrate how the quality policy for the distribution of electricity, managed by the Brazilian regulatory agency - ANEEL - through continuity indicators (DEC and FEC, DIC and FIC), is inefficient and brings damage to poor consumers. The problem involves the definition of electricity quality policy outlined by ANEEL, which allows power distributors to choose to service consumers classified as low-income less efficiently. The results corroborate the hypothesis of the study, with consumers classified as low-income receiving worse-quality electricity.

Book Description
Since the late 1980s, policy makers and regulators in a number of countries have liberalized, restructured or "deregulated their electric power sector, typically by introducing competition at the generation and retail level. These experiments have resulted in vastly different outcomes - some highly encouraging, others utterly disastrous. However, many countries continue along the same path for a variety of reasons. Electricity Market Reform examines the most important competitive electricity markets around the world and provides definitive answers as to why some markets have performed admirably, while others have utterly failed, often with dire financial and cost consequences. The lessons contained within are direct relevance to regulators, policy makers, the investment community, industry, academics and graduate students of electricity markets worldwide. - Covers electicity market liberalization and deregulation on a worldwide scale - Features expert contributions from key people within the electricity sector

Book Description
This book is a comprehensive, clear, and well-organized description of applied quality regulation in the electricity sector as it is today. It creates an essential bridge linking the theoretical aspects of service quality regulation with country-specific applied mechanisms. As a special feature, the book offers a survey of the most innovative regulatory mechanisms under proposal, in test stages, or in effect in European countries.

Book Description
As “market referees”, regulators contribute to the delivery of essential public utilities. Their organisational culture, behaviour, actions and governance are important factors in how they, and the sectors they oversee, perform.
