That climate policies are costly is evident and therefore often creates major fears. But the alternative (no action) also has a cost. Mitigation costs and damages incurred depend on what the climate policies are; moreover, they are substitutes. This brings climate policies naturally in the realm...

We propose a development-compatible refunding system designed to mitigate climate change. Industrial countries pay an initial fee into a global fund. Each country chooses its national carbon tax. Part of the global fund is refunded to developing and industrial countries, in proportion to the...

To decarbonize the power sector policy-makers need to commit to long-term credible rules for climate and energy policy. Otherwise, time-inconsistent policy-making will impair investments into low-carbon technologies. However, the future benefits and costs of decarbonization are subject to...

We present a two-good, two-country overlapping generations model where emissions arise from production and each country has a domestic emission permit system. When one country unilaterally reduces her cap on emissions, her output available for domestic and foreign consumption diminishes more...

We model countries' choice of greenhouse gas (GHG) emissions as a dynamic game. Emissions generate immediate benefits to the emitting country but also increase atmospheric GHG concentrations that negatively affect present and future welfare of all countries. Because there are no international...

We study the effect of climate policy on companies' greenhouse gas emissions using emissions data for the headquarters and subsidiaries of the world's biggest manufacturing, energy, and utility companies. Our results suggest that financial incentives and legal requirements to audit energy use...

The future consequences of climate change are highly uncertain. Today, the exact size of possible future damages are widely unknown. Governments try to cope with these risks by investing in mitigation and adaptation measures. Mitigation aims at a reduction of greenhouse gas emissions whereas...

Unintended consequences of a pre-announced climate policy have been studied in a variety of situations. We show that early announcement of a carbon tax gives rise to a “Green-Paradox,” in that it increases polluting emissions in the interim period (between announcement and actual...

Climate mitigation policy should be imposed over a long period, and spur development of new technologies in order to make stabilization of green house gas concentrations economically feasible. The government may announce current and future policy packages that stimulate current R&D in...

This policy note investigates whether the current level of public support to environment-friendly technologies is sufficient to allow European countries to respond to the multiple challenges posed by climate change and other environmental concerns. We first lay out the justifications for...
