In the world economy with interdependent markets for fossil fuel and deposits, some coalition of countries fights climate change by purchasing and preserving fossil fuel deposits, which would be exploited otherwise. If the coalition’s policy parameters are the demand and supply of deposits...

Policies of lowering carbon demand may aggravate rather than alleviate climate change (green paradox). In a two-period three-country general equilibrium model with finite endowment of fossil fuel one country enforces an emissions cap in the first or second period. When that cap is tightened the...

We study the incidence of carbon-reduction and green-energy promotion policies in a general equilibrium small open economy that depends on imports of fossil fuels. The focus is on mixed policies that are either price based (emissions taxes and producer price subsidies for green energy) or...

Scientific expertise suggests that mitigating extreme world-wide climate change damages requires avoiding increases in the world mean temperature exceeding 2° Celsius. To achieve the two degree target, the cumulated global emissions must not exceed some limit, the so-called global carbon...

Internalizing the global negative externality of carbon emissions requires flattening the extraction path of non-renewable fossil-fuel resources (= world carbon emissions). Following Eichner and Pethig (2011b) we set up a two-country two-period model in which one of the countries represents a...

Internalizing the global negative externality of carbon emissions requires flattening the extraction path of world fossil energy resources (= world carbon emissions). We consider governments having sign-unconstrained emission taxes at their disposal and seeking to prevent world emissions from...

This note investigates the suitability of unilateral consumption taxes for alleviating climate change in a two-period two-country general equilibrium model with a finite stock of fossil fuel. We analyze the incidence of a unilateral consumption tax in the first period on world carbon emissions....

The basic model of the literature on self-enforcing international environmental agreements is a model of autarkic countries. We extend that model by international trade and investigate its impact on the performance of "Nash" coalitions and on their stability, in particular, in a general...

Under which conditions unilateral tightening of climate policy causes a weak or strong green paradox or even decreases social welfare has recently been studied by Hoel (2011). Hoel assumes that the costs of extracting fossil fuel are linear in output. We extend his model by allowing for...

We incorporate three important aspects of current climate policy, unilateralism, demand side approach and a climate target, in a multi-country model with flow dependent fossil fuel extraction costs and a backstop. It turns out that the optimal climate coalition should encompass all countries...
