This gives a ...
Technological change has become a major focus in environmental policy as well as in energy and climate policy. Indeed, there is a growing body of knowledge about how and in which direction technological change might have an impact on environmental resource constraints and how environmental policy might have an impact on this direction. In this article we introduce the contributions to this special ...
This study tests the hypothesis that the ongoing restructuring process in the European electricity sector, as well as market participants' adaptation to the new legal framework, have caused electricity wholesale day-ahead prices to converge towards arbitrage freeness. Using hourly cross-border capacity auction results at the Dutch-German and at the Danish-German border for the years 2002 to 2004, and ...
This paper investigates the degree of integration of natural gas markets in Europe, North America and Japan in the time period between the early 1990s and 2004. The relationship between international gas market prices and their relation to the oil price are explored through principal components analysis and Johansen likelihood-based cointegration procedure. Both of them show a high level of natural ...
