This paper analyzes the optimal mix of adaptation and mitigation expenditures in a cost-effective setting, in which countries cooperate to achieve a long-term stabilization target (550 CO₂-eq). It uses an Integrated Assessment Model (AD-WITCH) that describes the relationships between different...

The reduction of GHG emissions is one of the most important policy objectives worldwide. Nonetheless, concrete and effective measures to reduce them are hardly implemented. One of the main reasons for this deadlock is the fear that unilateral actions will reduce a country’s competitiveness,...

This paper surveys recent advances in climate models by emphasising how quantitative instruments can answer the main crucial questions addressed by the policymakers involved and therefore aid the formulation of effective global climate policies. The limits of existing models are highlighted and...

This paper analyses the costs and benefits of a fiscal reform designed to simultaneously increase environmental quality and employment. The investigation is carried out using an econometric general equilibrium model in which the labour market is unionised and segmented, i.e. in which demand,...

This paper analyses the relationship between different equity rules and the incentives to sign and ratify a climate agreement. A widespread conjecture suggests that a more equitable ex-ante distribution of the burden of reducing emissions would provide the right incentives for more countries -...

It has become commonly accepted that a successful climate strategy should compound mitigation and adaptation. The accurate combination between adaptation and mitigation that can best address climate change is still an open question. This paper proposes a framework that integrates mitigation,...

The reduction of GHG emissions is one of the most important policy objectives worldwide. Nonetheless, concrete and effective measures to reduce them are hardly implemented. One of the main reasons for this deadlock is the fear that unilateral actions will reduce a country's competitiveness, and...

The latest round of international negotiations in Copenhagen led to a set of commitments on emission reduction which are unlikely to stabilise global warming below or around 2°C. As a consequence, in the absence of additional ambitious policy measures, adaptation will be needed to address...

Climate change is likely to have relevant effects on our future socio-economic systems. It is therefore important to identify how markets and policy jointly react to expected climate change to protect our societies and well-being. This study addresses this issue by carrying out an integrated...
