Targeted Pricing and Consumer Data Sharing among Rivals

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 percent ...

Targeted Pricing and Customer Data Sharing among Rivals

It is increasingly observable that competitors in different industries share customer data, which can be used for targeted pricing. We propose a modified Hotelling model with two-dimensional consumer heterogeneity to analyze the incentives for such sharing and its ensuing welfare effects. We show that these incentives depend on the type of customer data and on consumer heterogeneity in the strength ...

Trade and the Environment: The Role of Firm Heterogeneity

This paper derives a new effect of trade liberalisation on the quality of the environment. We show that in the presence of heterogeneous firms the aggregate volume of emissions is influenced not only by the long-established scale effect, but also by a reallocation effect resulting from an increase in the relative size of more productive firms. We show how the relative importance of these effects, and ...

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 ...

Europe's Twenties: A Study Using the WIATEC Model

In this paper, we use a computable general equilibrium model (WIATEC) to study the potential impact of implementing Europe's 20-20-20 climate policy. The results show that the economic costs of implementing the policy are only moderate and within the range of recent empirical evidence. Furthermore, they also indicate that there is a possibility that the existing allocations to the Europena sectors ...

Green, Brown, and Now White Certificates: Are Three One Too Many? A Micromodel of Market Interaction

Our paper deals with modeling the effects of introducing a market-based tool for improving end-users' efficiency in an energy market which is already regulated through a cap-and-trade system for green house gas emissions and a quota system meant to improve competitiveness of energy produced using renewable resources. Our results show that the regulation of energy demand achieves its underlying objects ...

Supplier Fixed Costs and Retail Market Monopolization

Considering a vertical structure with perfectly competitive upstream firms that deliver a homogenous good to a differentiated retail duopoly, we show that upstream fixed costs may help to monopolize the downstream market. We find that downstream prices increase in upstream firms’ fixed costs when both intra- and interbrand competition exist. Our findings contradict the common wisdom that fixed costs ...

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 ...
