We analyze a drastic price increase in the German auction market for reserve power, which did not appear to be driven by increased costs. Studying the market structure and individual bidding strategies, we find evidence for collusive behavior in an environment with repeated auctions, pivotal...

The harmonization and integration of separate national energy markets to an interconnected internal European market is a top priority of the European Commission. However, as energy policy largely remains subject to national sovereignty, a higher degree of integration can cause unilateral...

This paper proposes that the national focus of energy ‘rebound’ studies should be extended to an international context in the presence of supra-national agreements such as EU 20-20-20. The potential for energy efficiency improvements in one nation to impact energy use in others means that...

The German response to the Fukushima nuclear power plant incident was possibly the most significant change of policy towards nuclear power outside Japan, leading to a sudden and very significant shift in the underlying power generation structure in Germany. This provides a very useful natural...

Iran is an energy-rich country and one of the world's main oil-exporters, but its own rapid energy consumption in recent years has raised concerns about the ability of the country to continue exporting oil in the future. Economic growth, massive energy subsidies, and mismanagement of the energy...

This article explores key market design issues to be addressed in future electricity markets dominated by intermittent renewable generation with near zero private marginal costs for generating electricity. Changing technology mixes will change market outcomes, but they do not change the...

The benefits of smoothing demand peaks in the electricity market has been widely recognised. European countries such Spain and some of the Scandinavian countries have recently given to the consumers the possibility to face the spot prices instead of having a fixed tariffs determined by...

We compare a range of energy efficiency policies in a durable good market subject to both energy-use externalities and price-quality discrimination by a monopolist. We find that the social optimum can be achieved with differentiated subsidies. With ad valorem subsidies, the subsidization of the...

The Chinese leadership has determined to assign the market a decisive role in allocating resources. To have the market to play that role, getting the energy prices right is crucial because this sends clear signals to both producers and consumers of energy. While the overall trend of China's...

In addition to the already present Climate and Energy package, the European Union (EU) plans to include a binding target to reduce energy consumption. We analyze the rationales the EU invokes to justify such an overlapping and develop a minimal common framework to study interactions arising from...
