Der deutsche Strommarkt ist im Umbruch. Strom aus erneuerbaren Quellen verdrängt solchen aus konventioneller Erzeugung. Gleichzeitig wird immer mehr Elektrizität im Norden Deutschlands produziert und muss zu den Verbrauchern im Süden transportiert werden. Die bestehende Marktordung fordert...

Current climate and energy policy has to operate under an ex-ante unforeseen economic crisis. An obvious consequence is the collapse of prices for carbon emission allowances as, for example, seen in the European Union. However, this price collapse may be amplified by the interaction of a carbon...

One of the most promising ways of meeting climate policy targets is improving energy efficiency, i.e. reducing the amount of scarce and polluting resources needed to produce a given quantity of output. This study undertakes an empirical exercise using the World Input-Output Database (WIOD), a...

We find an asymmetric pass-through of European Emission Allowance (EUA) prices to wholesale electricity prices in Germany and show that this asymmetry has disappeared in response to a report on investigations by the competition authority. The asymmetric pricing pattern, however, was not detected...

In January 2007, first evidence of an asymmetric pass-through of CO2 emission allowance prices was reported for the German electricity spot market. This paper explores the theoretical basis for such an asymmetry in the context of a supply function bidding duopoly. It interprets fluctuating...

This paper studies the effect of forward contracts on the stability of collusion among firms, competing in supply functions on the spot market. A forward market can increase the range of discount factors which allow to sustain collusion. On the contrary, collusion is destabilised when a...

The parameterisation of energy and climate policies often depends on the technology, which is price-setting in electricity markets. We propose two simple approaches to determine marginal technologies in electricity wholesale from available data. Both approaches are complementary, computationally...
