Economic thought on climate policy as an instance of environmental regulation is strongly influenced by the principle of a uniform carbon price. Economists acknowledge that this principle breaks down in a second-best world with other distortions, such as taxes and market power in domestic and...

In this paper we analyze how ratification uncertainty impacts the optimal terms of international environmental agreements (IEAs). We relax the frequent assumption of countries as unitary actors by modeling the ratification stage through uncertain preferences of a ratifying agent (e.g. the...

This paper studies within a multi-country model with international trade the stability of international environmental agreements (IEAs) when countries regulate carbon emissions either by taxes or caps. Regardless of whether coalitions play Nash or are Stackelberg leaders the principal message is...

"After the failure of the Copenhagen conference, climate finance has become the buzzword of international climate negotiations. A "fast-track" volume of 30 billion $ has been promised by industrialised countries for emissions mitigation and adaptation activities in developing countries. A...

We estimate the causal impact of the EU Emissions Trading Scheme on manufacturing firms using comprehensive panel data from the German production census. Semiparametric matching estimators yield robust evidence that the policy caused treated firms to abate one fifth of their CO2 emissions...

The unilateral introduction of an emissions price can induce firms to relocate to other countries with less stringent environmental regulation. However, firms may be able to reduce the emissions costs in their home country by investing into low-carbon technologies or equipment (abatement...

A major concern in climate negotiations is that decarbonization may significantly hurt the development process. This paper shows that international specialization can contribute to making environmental and economic objectives compatible. When carbon efficiency differs between two trading...

Emission inequality across countries and the contribution of the energy mix and the sectoral composition of a country s energy use are of central importance to the climate debate. We analyze the evolution of inequality in global CO2 per capita emissions using both historical data on...
