This paper provides a comprehensive global, regional, and country-level update of: (i) efficient fossil fuel prices to reflect their full private and social costs; and (ii) subsidies implied by mispricing fuels. The methodology improves over previous IMF analyses through more sophisticated...

This paper estimates the long-run elasticity of emissions and carbon-related government revenues to carbon pricing. It is based on the OECD Effective Carbon Rates database, the most comprehensive cross-country longitudinal database on direct and indirect carbon pricing. Econometric estimates...

The persistent uncertainty about mid-century CO2 emissions targets is likely to affect not only the technological choices that energy-producing firms will make in the future but also their current investment decisions. We illustrate this effect on CO2 price and global energy transition within a...

The policy instruments for emissions reductions will be an integral part of a Post Kyoto Climate Regime. In this paper we compare a harmonized international carbon tax to a cap and trade system with different allocation rules for the emission caps. The caps are based either on the requirement...

Because of large economic and environmental asymmetries among world regions and the incentive to free ride, an international climate Regime with broad participation is hard to reach. Most of the so far proposed Regimes base on an allocation of emission rights that is to be perceived as fair....

This paper studies the long-term distribution of energy-efficiency outcomes in the German residential sector. To uncover the underlying energy efficiency of buildings, we estimate the causal response of building-level heat energy demand to variability in heating degree days. We examine...

Different reports including the broadly cited OECD fossil fuel subsidy inventory arrive at high monetary values of fossil fuel subsidies and suggest that phasing out these subsidies has a high potential to increase the efficiency of climate policies. We show that the inventory approach gives...
