Refunding ETS Proceeds to Spur the Diffusion of Renewable Energies: An Analysis Based on the Dynamic Oligopolistic Electricity Market Model EMELIE

We use a quantitative electricity market model to analyze the welfare effects of refunding a share of the emission trading proceeds to support renewable energy technologies that are subject to experience effects. We compare effects of supporting renewable energies under both perfect and oligopolistic competition with competitive fringe firms and emission trading regimes that achieve 70 and 80% emission ...

How Emission Certificate Allocations Distort Fossil Investments: The German Example

Despite political activities to foster a low-carbon energy transition, Germany currently sees a considerable number of new coal power plants being added to its power mix. There are several possible drivers for this "dash for coal", but it is widely accepted that windfall profits gained through free allocation of ETS certificates play an important role. Yet the quantification of allocation-related investment ...

Market Driven Power Plant Investment Perspectives in Europe: Climate Policy and Technology Scenarios until 2050 in the Model EMELIE-ESY

EMELIE-ESY is a partial equilibrium model with focus on electricity markets. Private investors optimize their generation capacity investment and dispatch over the horizon 2010 to 2050. In the framework of the Energy Modeling Forum 28, we investigate how climate policy regimes affect market developments under different technology availabilities and climate policies on the European power markets. The ...

The Welfare Impact of Parallel Imports: A Structural Approach Applied to the German Market for Oral Anti-Diabetics

We investigate the welfare impact of parallel imports using a large panel data set containing monthly information on sales, ex-factory prices, and further product characteristics for all 700 anti-diabetic drugs sold in Germany between 2004 and 2010. We estimate a two-stage nested logit model of demand and, based on an oligopolistic model of multiproduct firms, we then recover the marginal costs and ...

Climate Protection through Biochar in German Agriculture: Potentials and Costs

In recent years, there has been much discussion about biochar - a carbonaceous product made of biomass - as a promising technique for mitigating climate change. In particular, this method has the potential to remove carbon dioxide from the atmosphere for the long term by incorporating biochar into the soil while enhancing soil fertility at the same time. A research project conducted by DIW Berlin calculated ...

Crop Failures and Export Tariffs

We analyse a stylized model of the world grain market characterized by a small oligopoly of traders with market power on both the supply and demand side. Crops are stochastic and exporting countries can impose export tariffs to protect domestic food prices. Our first results is that export tariffs are strategic complements and that for poor harvests equilibrium tariffs can explode (shedding some light ...

Financial Incentives for Low Carbon Investment: Dissertation

Zur Bekämpfung des Klimawandels haben politische Entscheidungsträger auf europäischer, nationaler und regionaler Regierungsebene CO2-Reduktionsziele formuliert, die erhebliche Investitionen erfordern. Studien haben zahlreiche Marktbarrieren ermittelt, die diese Investitionen verhindern. Zur Überwindung dieser Barrieren wurden regulatorische, preis- und informationsbasierte Politikinstrumente implementiert. ...

Strategic Behaviour in Energy Markets: Advances in Complementarity and Multi-Stage Equilibrium Modelling ; Dissertation

Diese Dissertation untersucht mehrere energiewirtschaftliche Fragestellungen, in denen Marktmacht eine besondere Rolle spielt; mittels spieltheoretischer Ansätze werden die strategischen Interaktionen mathematisch formuliert und anhand numerischer Methoden Gleichgewichte der Spiele identifiziert. Der Beitrag zum wissenschaftlichen Diskurs rund um den Themenbereich Marktmacht in der Energiewirtschaft ...
