This paper reviews the existing literature on modelling the macroeconomic consequences of the transition to a circular economy. It provides insights into the current state of the art on modelling policies to improve resource efficiency and the transition to a circular economy by examining 24...

Energy-Economy-Environment (E3) modelers have called to develop “hybrid” models that aim at reconciling bottom-up and top-down approaches (Hourcade et al. 2006) to overtake their respective limits: on the one hand, engineers focus on the fine representation of technologies but without taking...

Ghersi and Hourcade (2006) proved that the impact of technical constraints (often derived from bottom-up models) may result in strong macroeconomic impacts. Therefore, the modeling choices of the representation of technical change in CGE models affect the evaluation of the cost of climate and...

This study explores the importance of bioenergy to potential future energy transformation and climate change management. Using a large inter-model comparison of 15 models, we comprehensively characterize and analyze future dependence on, and the value of, bioenergy in achieving potential...

This paper presents a dynamic model of the reinsurance market for catastrophe risks. The model is based on the classical capacity-constraint assumption. Reinsurers choose every year the quantity of risk they cover and the level of external capital they raise to cover these risks. The model...

Seven long-term prospective studies representing the energy trajectories consistent with a Factor Four, i.e. a 75% reduction of greenhouse gases emissions in 2050 in France have been identified. We analyze their methodology and the high dispersion of results. Then we discuss the role of...

In addition to the already present Climate and Energy package, the European Union (EU) plans to include a binding target to reduce energy consumption. We analyze the rationales the EU invokes to justify such an overlapping and develop a minimal common framework to study interactions arising from...

Le modèle d'équilibre général Imaclim-R France est utilisé pour examiner différentes stratégies de transition énergétique menant à une trajectoire 'Facteur 4'. Le bilan macroéconomique d'un jeu d'hypothèses sur les conditions techniques de l'offre et la demande d'énergie varie...

In addition to the already present Climate and Energy package, the European Union (EU) plans to include a binding target to reduce energy consumption. We analyze the rationales the EU invokes to justify such an overlapping and develop a minimal common framework to study interactions arising from...

The implementation of climate policies is often hindered by a lack of acceptability as well as the lack of long-term vision of stakeholders. Mitigation scenarios exercises allow the debate; however the scenario design process lacks transparency and stakeholders' (and citizens') involvement, which...
