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...

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 Energy Modeling Forum 28 (EMF28) study systematically explores the energy system transition required to meet the European goal of reducing greenhouse gas (GHG) emissions by 80% by 2050. The 80% scenario is compared to a reference case that aims to achieve a 40% GHG reduction target. The...

We critically review the Kyoto Protocol and thirteen alternative policy architectures for addressing the threat of global climate change. We employ six criteria to evaluate the policy proposals: environmental outcome, dynamic efficiency, cost effectiveness, equity, flexibility in the presence of...

Scientific and economic consensus increasingly points to the need for a credible and cost-effective approach to address the threat of global climate change, but the Kyoto Protocol to the U.N. Framework Convention on Climate Change appears incapable of inducing significant participation and...

This paper investigates the economic incentives of countries to cooperate on international adaptation financing. Adaptation is generally implicitly incorporated in the climate change damage functions as used in Integrated Assessment Models. We replace the implicit decision on adaptation with...

The paper proves the existence and uniqueness of a noncooperative steady state in the context of a model of climate change. It also explores the possibility of cooperation and attainment of an optimal steady state. It is shown that the problem is similar to that in the static model (Chander and...

Contrary to current notions about water abundance in Lebanon, the country is facing serious problems of unavailability, both in quantity and quality, geographical and sectoral. Even though this is due to several existing human-related aspects, i.e. management, ill-finance, non-integration and...
