Book excerpt: Whether it concerns environmental economics or law and economics, two areas of science in which I feel well at home, publisher Edward Elgar is a front-runner time and again with relevant and solid publications. This time is no exception, with this book edited by Francesco Gullì. Edwin Woerdman, Tijdschrift voor Energierecht Why do power prices seem to be correlated with the carbon price in some markets and not in others? This crucial question is at the centre of Francesco Gullì s enlightening book, through which the contributing authors investigate a number of related issues. In particular, they explore why power firms are not consistent in passing-through into power prices the opportunity cost of carbon. They also examine the relationship between the pass-through mechanism and the structure of the power market. This informative study brings together and interprets original contributions by leading experts from every EU country. Beginning with an overview of the European Union Emissions Trading System (EU ETS) along with an in-depth analysis of the early results and the theoretical issues involved, the book then goes on to explore the main European power markets via a number of empirical case studies. Overall, this volume offers a genuinely comprehensive analysis on the relationship between carbon and power markets and, as such, will prove a valuable contribution to the debate on the EU ETS and to the literature on the interaction between environmental policy and the structure of environmentally regulated markets. Markets for Carbon and Power Pricing in Europe will be of great interest to researchers and academics within general economics, environmental and energy economics. It will also be warmly welcomed by policymakers, regulators and power sector operators.
