    Estimating Alternative Technology Sets in Nonparametric Efficiency Analysis: Restriction Tests for Panel and Clustered Data

    Nonparametric efficiency analysis has become a widely applied technique to support industrial benchmarking as well as a variety of incentive- based regulation policies. In practice such exercises are often plagued by incomplete knowledge about the correct specifications of inputs and outputs. Simar and Wilson (2001) and Schubert and Simar (2011) propose restriction tests to support such specification ...

    The Role of Hedging in Carbon Markets

    In the European Emissions Trading System, power generators hold CO2 allowances to hedge for future power sales. First, we model their aggregate hedging demand in response to changes in expectations of future fuel, carbon and power prices from forward prices. This partial equilibrium analysis is then integrated into a two period model of the supply and demand of CO2 allowances considering also emissions ...

    Europäischer Emissionshandel: durch Backloading Zeit für Strukturreform gewinnen

    Der europäische Emissionshandel soll den Ausstoß klimaschädlicher Treibausgase begrenzen und Anreize für Investitionen in emissionsarme Technologien geben. In den letzten Jahren hat sich jedoch ein großer Überschuss an Emissionszertifikaten angesammelt. Gründe hierfür sind vor allem unerwartete Emissionsminderungen aufgrund der Wirtschaftskrise und ein starker Zustrom an internationalen Emissionsgutschriften. ...

    EU Emissions Trading: The Need for Cap Adjustment in Response to External Shocks and Unexpected Developments? Environmental Research of the German Federal Ministry of the Environment, Nature Conservation and Nuclear Safety ; Project-No. (FKZ) 3711 41 504

    The effectiveness of an emissions trading system in terms of reducing greenhouse gas emissions is mainly due to the magnitude of the specified emission cap. Assuming sufficient control, a quantitative emission target defined in such a way is quasi automatically achieved by the limited allocation of emission allowances. In functioning markets, this coincides with a somewhat higher allowance price as ...

    Renewable Electric Energy Integration: Quantifying the Value of Design of Markets for International Transmission Capacity

    Integrating large quantities of supply-driven renewable electricity generation remains a political and operational challenge. One of the main obstacles in Europe to installing at least 200 GWs of power from variable renewable sources is how to deal with the insufficient network capacity and the congestion that will result from new flow patterns. We model the current methodology for controlling congestion ...

    Electric Vehicles in Imperfect Electricity Markets: The Case of Germany

    We use a game-theoretic model to analyze the impacts of a hypothetical fleet of plug-in electric vehicles on the imperfectly competitive German electricity market. Electric vehicles bring both additional demand and additional storage capacity to the market. We determine the effects on prices, welfare, and electricity generation for various cases with different players in charge of vehicle operations. ...

    Removing Cross-Border Capacity Bottlenecks in the European Natural Gas Market: A Proposed Merchant-Regulatory Mechanism

    We propose a merchant-regulatory framework to promote investment in the European natural gas network infrastructure based on a price cap over two-part tariffs. As suggested by Vogelsang (2001) and Hogan et al. (2010), a profit maximizing network operator facing this regulatory constraint will intertemporally rebalance the variable and fixed part of its two-part tariff so as to expand the congested ...

    Merger Efficiency and Welfare Implications of Buyer Power

    This paper analyzes the welfare implications of buyer mergers, which are mergers between downstream firms from different markets. We focus on the interaction between the merger's effects on downstream efficiency and on buyer power in a setup where one manufacturer with a non-linear cost function sells to two locally competitive retail markets. We show that size discounts for the merged entity has no ...

    Rationales und irrationales Verhalten in der russischen Klimapolitik

    Russland nutzt die internationalen Klimaschutzinstrumente nur geringfügig und verspätet, obwohl die russische Wirtschaft davon profitieren könnte. Auch einer Verlängerung des Kyoto-Protokolls steht Russland abweisend gegenüber. Dieses scheinbar irrationale Verhalten hat nachvollziehbare Gründe, wenn man die unveränderte Energieabhängigkeit der russischen Wirtschaft betrachtet. Die Klimaschutzstrategien ...
