We modify the vertically differentiated duopoly model by André et al. (2009) replacing Bertrand with Cournot behaviour, and we characterise the region wherein a Porter-type result takes place. We show that the Porter hypothesis applies in an equilibrium taking always the form of a prisoner's...

In the basic model of international environmental agreements (IEAs) (Barrett 1994, Rubio and Ulph 2006) extended by international trade, self- enforcing - or stable - IEAs may comprise up to 60% of all countries (Eichner and Pethig 2013). But these IEAs reduce total emissions only slightly...

We investigate the performance of a consumption-based carbon tax – implemented by full border carbon adjustment – as an instrument of unilateral climate damage mitigation in a two-period two-country general equilibrium model with a finite stock of fossil fuel. The implementation of that tax...

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...

Acquired wisdom has it that the allocation of pollution rights to firms hinders their willingness to undertake uncertain R&D projects for environmental-friendly technologies. We revisit this issue in a model where firms strategically choose whether to participate in a lottery to attain pollution...

In a multi-country model with mobile capital and global pollution this paper analyzes the stability of self-enforcing environmental agreements (IEAs) when the coalition formed by the signatory countries plays Nash. In accordance with previous environmental literature we show that there exists a...

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...

In the basic model of the literature on international environmental agreements (IEAs) (Barrett 1994; Rubio and Ulph 2006) the number of signatories of selfenforcing IEAs does not exceed three, if non-positive emissions are ruled out. We extend that model by introducing a composite consumer good and...
