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...

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

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...

This paper analyzes the formation of self-enforcing climate agreements, or stable climate coalitions, when all countries have the option to fight climate change by purchasing (the right to extract) fossil-energy deposits. First, we consider the stand-alone deposit purchase policy and then...

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...

In Harstad´s (2012) model, climate damage only hits one group of countries, called the coalition, and the coalition´s climate policy consists of capping own fuel demand and supply combined with the purchase of fossil fuel deposits for preservation. Harstad´s Theorem 1 states that if the...

In Harstad's (2012) model, climate damage only hits one group of countries, called the coalition, and the coalition's climate policy consists of capping own fuel de- mand and supply combined with the purchase of fossil fuel deposits for preserva- tion. Harstad's Theorem 1 states that if the...

We analyze strategies to conserve worldwide biodiversity assuming that biodiversity and ecosystem services are positively correlated with that share of land that is effectively protected by land-use restrictions against the deterioration of ecosystems (land-use approach). The willingness-to-pay...
