This paper investigates the optimal timing of greenhouse gas abatement efforts in a multi-sectoral model with economic inertia, each sector having a limited abatement potential. It defines economic inertia as the conjunction of technical inertia --- a social planner chooses investment on...

This article analyzes the eff ect of risk and risk aversion on the long-term equilibrium technology mix in an electricity market. It develops a model where fi rms can invest in baseload plants with a fi xed variable cost and peak plants with a random variable cost, and demand for electricity...

The choice of a portfolio of technologies by risk averse firms is analyzed. Two technologies with random marginal costs are available to produce a homogeneous good. If the risks associated to the technologies are correlated firms might invest in a technology with a negative expected return or...

The optimal timing, sectoral distribution, and cost of greenhouse gas emission reductions is different when abatement is obtained though abatement expenditures chosen along an abatement cost curve, or through investment in low-carbon capital. In the latter framework, optimal investment costs...

The objective of this paper is to analyze the effects public regulatory tools for food safety, notably maximum admitted contamination thresholds and official controls performed at importing country’s borders on both developing countries’ market access and consumers’ health. An Industrial...

In the paper, we propose a methodological way of leading an economical assessment of innovative cropping systems (ICSs). The originality lies in the integration of the crop management flexibility and the farmers’ risk perception and risk preferences. Two conventional cropping systems have been...

Débuté en 2008, le projet de recherche CAP-IRE se proposait d’étudier les différents impacts et les différents rôles de la PAC sur l’économie rurale au sens large. L’objectif général de ce projet était ainsi d’améliorer la compréhension des mécanismes socio-économiques...

Agricultural land fragmentation is widespread and may affect farmers’ decisions and impact farm performance, either negatively or positively. We investigated this impact for the western region of Brittany, France, in 2007. To do so, we regressed a set of performance indicators on a set of...

Agricultural land fragmentation is widespread and may affect farmers’ decisions and therefore have an impact on the performence of farms, wheter in a negative or in a positive way. In this paper we test whether the relationship is positive or negative for French western region of Brittany in...
