Outbreaks of animal diseases such as foot and mouth disease (FMD) are of great concern for agriculture. In this paper, we quantify the potential dynamic impacts of such a disease on Brittany, a French region with an important livestock sector. In order to do this, we develop a dynamic computable...

L'accord agricole du cycle d'Uruguay contient une définition du type d'aides aux agriculteurs pouvant être exemptées de l'engagement de réduction du soutien à l'agriculture. Ces aides, dites "découplées" (indépendantes des quantités produites), sont censées ne pas interférer avec les...

Deux scénarios de suppression des mesures de soutien interne dans le secteur français des céréales et des oléoprotéagineux (COP), avec ou sans maintien de la préférence communautaire, sont simulés avec MEGAAF. Une modélisation du bloc des importations de céréales issues des pays...

Cet article a pour principal objectif de mettre en évidence l'intérêt de la modélisation en équilibre général calculable (EGC) pour l'étude de problèmes agricoles. Les principes de la modélisation en EGC sont d'abord rappelés. Les modèles d'EGC diffèrent des modèles d'équilibre...

The financial development of agricultural markets is not recent. But, starting early 2000, a large amount of investments on commodity markets, including agriculture, have been realized using innovative instruments. And in 2007-08, the continuous increase of investment was simultaneous with...

Crop rotation effects and constraints are major determinants of farmers’ crop choices. Crop rotations are also keystone elements of most environmentally friendly cropping systems. The aim of this paper is twofold. First, it proposes simple tools for investigating optimal dynamic crop acreage...

The European public policy in favor of the biodiesel consumption is highly debated. Available estimates of the induced land use changes conclude that this policy is inefficient to reduce emissions of GreenHouse Gas. We show that the crop yield evolutions in these estimates are significantly...

Thanks to its empirical success, the gravity approach is widely used to explain trade patterns between countries. In this article we question the simple application of this approach to product/sector-level trade on two grounds. First, we demonstrate that the traditional Armington version of...
