The purpose of this article is twofold: First to discuss three misconceptions in the debate on climate policies: i) that de-growth is necessary, ii) that the market economy is part of the problem rather than part of the solution to climate change, and iii) that the only policy tool needed is to...

Denmark’s green growth strategy focuses on moving the energy system away from fossil fuels and investing in green technologies, while limiting greenhouse gas (GHG) emissions. On the whole, current policies should allow Denmark to reach near-term climate change targets, but may not be...

Korea’s greenhouse gas emissions almost doubled between 1990 and 2005, the highest growth rate in the OECD area. Korea recently set a target of reducing emissions by 30% by 2020 relative to a “business as usual” baseline, implying a 4% cut from the 2005 level. Achieving this objective in a...

We derive the optimal contributions to global climate policy when countries differ with respect to income level and pollution intensity. Countries' growth rates are determined endogenously, and abatement efficiency is improved by technical progress. We show that country heterogeneity has a...

We study clean energy subsidies in a quantitative climate-economy model. Clean energy subsidies decrease carbon emissions if and only if they lower the marginal product of dirty energy. The constrained-efficient subsidy equals the marginal external cost of dirty energy multiplied by the marginal...

We study clean energy subsidies in a quantitative climate-economy model. Clean en-ergy subsidies decrease carbon emissions if and only if they lower the marginal product of dirty energy. The constrained-efficient subsidy equals the marginal external cost of dirty energy multiplied by the...

One of the central ways that the costs of global warming are incorporated into U.S. law is in cost-benefit analysis of federal regulations. In 2010, to standardize analyses, an Interagency Working Group (IAWG) established a central estimate of the social cost of carbon (SCC) of $21/tCO2 drawn...

This paper investigates the joint impact of the European Union Emissions Trading System (EU ETS), Europe’s main climate change policy, on carbon emissions and economic performance of regulated companies. The impact on emissions is analysed using installation-level carbon emissions from...
