Calls for liberalizing cash crop sectors in sub-saharan Africa have been voiced for decades. Yet, the impact of reforms remains elusive in empirical studies. This paper offers new opportunities to solve this problem by creating precise and consistent market organisation indices for 25 African...

We present a spatial international trade model, GEO, which computes transportation costs bynot treating markets as dimensionless points and explicitly represents capacity shortages andinvestment decisions in new production capacities. We link it to CEMSIM, a partialequilibrium model of the world...

This paper analyses harmonization on fuel taxes between two coalitions. Harmonization is considered as a tool to mitigate greenhouse gas emissions, and reduce environmental costs. Domestic fuel producers can sell abroad, and their profits influence national governments in the negotiations. If...

In this paper, we study the main properties of the strong Berge equilibrium which is also a Pareto efficient (SBPE) and the strong Nash equilibrium (SNE). We prove that any SBPE is also a SNE, we prove also existence theorem of SBPE based on the KyFan inequality. Finally, we also provide a...

In this paper, we discuss the results of a sensitivity analysis of Res-IRF, an energy-economy model of the demand for space heating in French dwellings. Res-IRF has been developed for the purpose of increasing behavioral detail in the modeling of energy demand. The different drivers of energy...

This econometric study assesses the efficiency of the tax credit implemented in France in 2005 on dwelling retrofitting investments. A before-after estimation is performed at the extensive and intensive margins on micro data over 2001-2011, focusing on insulation measures (windows, walls, roofs,...

Policy makers as well as many economists recognize geological Carbon Capture and Sequestration (CCS) as a key option to avoid costly emission reduction. While an extreme perspective is to envision CCS as a magic bullet to solve the issue of climate change, the economics perspective is more...

Les politiques de sécurité énergétique et les politiques climatiques sont souvent considérées comme les deux faces d'une même pièce, leurs objectifs étant identiques, ou tout au moins complémentaires. Pourtant, si ces politiques partagent indéniablement une cause commune, la demande...

Climate change mitigation requires to replace preexisting carbon-intensive capital with different types of cleaner capital. Coal power and inefficient thermal engines may be phased out by gas power and efficient thermal engines or by renewable power and electric vehicles. We derive the optimal...

Emission trading systems have been recently proposed in diffrerent regions to reduce polluting emissions (e.g. in the European Union for carbon dioxide). One of the objectives of these systems is to encourage firms to adopt advanced abatement technologies. However permits create an incentive to...
