Questions of burden sharing receive increasing attention in the climate change regime. This paper introduces the WESA-mechanism (WESA = Walrasian Equilibrium with the Stand Alone upper bound) for the fair division of common property resources and monetary compensations. Furthermore, the...

In this paper the climate change effect is an unforeseen earth temperature level above which a negative externality on technology and hence on society's welfare is exerted. We use a dynamic overlapping generations model to develop a positive analysis of the growth path of an economy with the...

We compare taxes and quotas when firms and the regulator have asymmetric information about abatement costs. Damages are caused by a stock pollutant. Uncertainty enters multiplicatively, i.e. it affects the slope rather than the intercept of abatement costs. We calibrate the model using cost and...

When economic agents decide their optimal environmental behavior, they have to take into account non continuos evolutionary trends and irreversible changes characterising environmental phenomena. Given the still non perfect biophysical and economic knowledge, decisions have to be taken in an...

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...

This paper analyses the policy relevance of the dominant uncertainties in our current scientific understanding of the terrestrial climate system, and provides further evidence for the need to radically transform - this century - our global infrastructure of energy supply, given the global...

In this paper, we use the two region CETA-M model to explore some related issues raised by the current interest in CO2 concentration targets as a possible climate change policy objective. First, we identify possible cost and benefit assumptions that would make particular concentration ceilings...

General Circulation Models (GCMs) are considered to provide the best basis for the construction of future climate change scenarios. GCM output cannot, however, be widely or directly used in many impact assessments because of their relatively coarse spatial scale. In order to overcome the...
