Ziel dieses Papers ist es, die derzeitige Diskussion bzgl. des sog. Merit-Order Effektes der erneuerbaren Energien auf den Strompreis kritisch zu beleuchten. Veröffentlichungen, welche diesen Effekt quantifizieren, weisen für die Jahre 2005 und 2006 einen Großhandels-Strompreis senkenden...

The increase of fuel extraction costs as well as of temperature will make it likely that in the medium-term future technological or political measures against global warming may be implemented. In assessments of a current climate policy the possibility of medium-term future developments like...

Under which conditions unilateral tightening of climate policy causes a weak or strong green paradox or even decreases social welfare has recently been studied by Hoel (2011). Hoel assumes that the costs of extracting fossil fuel are linear in output. We extend his model by allowing for...

We incorporate three important aspects of current climate policy, unilateralism, demand side approach and a climate target, in a multi-country model with flow dependent fossil fuel extraction costs and a backstop. It turns out that the optimal climate coalition should encompass all countries...

The increase of fuel extraction costs as well as of temperature will make it likely that in the medium-term future technological or political measures against global warming may be implemented. In assessments of a current climate policy the possibility of medium-term future developments like...

The penetration of Variable Renewable Energies (VREs) in the electricity mix poses serious challenges in terms of management of the electrical grids, as the associated variability and non-dispatchability are in contrast with the requirement that the load be instantaneously equalized by the...

With the increasing integration of wind and photovoltaic power in the whole European power system, there is a longing for detecting how to trade energy in the ever-changing intraday market from electric power industries. The intraday trading becomes even more relevant in the wake of the European...

We develop an analytical model to derive the competitive market equilibrium for electricity spot and reserve markets under stochastic demand and uncertain renewable electricity generation. We then derive the welfare-optimal provision of reserves. At first-best, cost of reserve capacity is...

Is green consumerism beneficial to the environment and the economy? To shed light on this question, we study the political economy of environmental regulations in a model with neutral and green consumers where the latter derive some warm glow from buying a good of higher environmental quality...
