This paper investigates the relative economic and environmental outcomes of price versus quantity mechanisms to control GHG emissions when abatement costs are uncertain. In particular, we evaluate the impacts on policy costs, CO2 emissions and energy R&D for a stringent mitigation target of 550...

Climate-economy models aiming at quantifying the costs and effects of climate change impacts and policies have become important tools for climate policy decision-making. Although there are several important dimensions along which models differ, this paper focuses on a key component of climate...

This paper analyses the incentives to participate in and the stability of international climate coalitions. Using the integrated assessment model WITCH, the analysis of coalitions' profitability and stability is performed under alternative assumptions concerning the pure rate of time preference,...

Since the framework convention of Rio, actual environmental negotiations on climate change aim at inducing all world countries to sign global environmental agreements to reduce greenhouse gas emissions. Despite the past unsuccessful attempts, even current negotiations seem to pursue the same...

In this paper an n-player non-co-operative game is used to model countries' decision of whether or not to sign an international agreement on climate change control. The stable coalition structure of the game is defined and then computed for a climate game in which the role of carbon leakage is...

In this paper a simple model is used to analyse the strategic behaviour of countries that bargain over CO2 emission reductions. Five main world regions are considered and their incentives to sign an international agreement on climate change control are analysed. A non-cooperative approach to...

The 1998 Kyoto protocol signalled a new earnestness of international intent toward addressing the perceived risk of climate change. Kyoto demands that developed nations turn their economies so as to hit differentiated, sub-1990 level carbon emission targets within the next decade or so. But when...

The paper describes and comments the Italian policies and measures planned to implement the 1997 Kyoto Protocol, with the aim of contributing to the overall reduction of greenhouse gases (GHG) emissions in industrialised countries over the next 10-15 years. The first part of the paper describes...

Within this paper, we analyse the fulfilment of the Kyoto-emissions reduction com-mitment exemplary in Germany and its implication on long-term paths of all macro-variables. Germany, like all other industrial or Annex B coun-tries, has to reduce its emissions by 2010 and after what we call a...

The purpose of the present paper is to describe the role of uncertainty and technical change in an environmental context. Which impact does ecological uncertainty have on physical and R&D investments' decisions? How are pollution trajectories modified when uncertainty is taken into account? To...
