The Doha climate talks in December 2012, wrapped up lines of negotiation that were begun years before in Bali. Negotiators resolved contentious questions about the future of the Kyoto Protocol and finally put the constraints of the Bali agenda behind them. Now they need turn to developing by...

In a context of laissez-faire, the propositions established in this paper shed light on the evolution of the problem of greenhouse gas (GHG) accumulation in the atmosphere for each type of strategic behaviour resulting from countries' interconnection on global markets. In a framework of strong...

This paper studies the implications for climate policy of the interactions between environmental and knowledge externalities. Using a numerical analysis performed with the hybrid integrated assessment model WITCH, extended to include mutual spillovers between the energy and the non-energy...

In this paper we argue that when a subgroup of countries cooperate on emission reduction, the optimal response of non-signatory countries reflects the interaction between three potentially opposing factors, the incentive to free-ride on the benefits of cooperation, the incentive to expand the...

We demonstrate the advantages of a climate treaty based solely on rules for international permit markets when there is uncertainty about abatement costs and environmental damages. Such a ‘Rules Treaty’ comprises a scaling factor and a refunding rule. Each signatory can freely choose the...

Some recent papers by Dell et al. (2009) and Dell et al. (2012) (DJO) relating weather and economic outcomes, have delivered meaningful messages with clear implications to the effects of a changing climate. In a nutshell, the authors claim that a 1°C increase in global average temperatures...
