The large-scale cultivation of transgenic crops producing Bacillus thuringiensis (Bt) toxins have already lead to the evolution of Bt resistance in some pest populations targeted by these crops. We used the F2 screening method for further estimating the frequency of resistance alleles of the...

The western corn rootworm, Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae), is a major pest of corn, Zea mays L., in North America that has recently invaded Europe. A loss of ovipositional fidelity to cornfields has allowed the species to circumvent crop rotation as a means of...

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...

Regional trade agreements (RTAs) have become increasingly prevalent since the early 1990s. However few studies exist on the effects of RTAs on agrifood trade and very little differentiate trade in raw agricultural products from trade in processed food products. This paper focuses on the agrifood...

We analyze the impact of labour market rigidities on tax competition betweentwo imperfectly integrated countries. Following a shift from a competitive to a unionizedlabour market in both countries, the capital tax can be adjusted upward in the countrywith the less rigid labour market, whereas...
