Cap-and-trade programs such as the European Union’s Emissions Trading System (EU ETS) expose firms to considerable risks, to which the firms can respond with hedging. We develop an intertemporal stochastic equilibrium model to analyze the implications of hedging by risk-averse firms. We show...

Germany aims to phase out coal to achieve its 2030 climate target, for which a UK-style carbon price floor is considered. But this measure comes with risks related to the uncertainty about what price level is sufficient, and the waterbed effect arising from unilateral policy under the EU-ETS....

Die deutsche Klimapolitik benötigt eine grundlegende Neuausrichtung. Deutschland muss im Rahmen der EU-Lastenteilungsverordnung bis 2030 seine Emissionen im Verkehrs-, Gebäude- und Landwirtschaftssektor sowie in Teilen des Industrie- und Energiesektors um 38 Prozent gegenüber 2005 vermindern,...

Germany has an ambitious climate target for 2030 that cannot be achieved without reducing the high share of coal in power generation. In the face of this, the country has set up a commission to phase out coal. A UK-style carbon price floor is one of the options being considered. Yet implementing...

Long-term commitment is crucial for the dynamic efficiency of intertemporal cap-and-trade programs. Discretionary interventions in such programs could destabilize the market, and necessitate subsequent corrective interventions that instigate regulatory instability (Kydland and Prescott, 1977)....
