We use a spatially-explicit analytical framework to compare mandatory refuges and a tax on the resistant variety as regulation instruments for pest resistance management. Because the extraction of the common-pool pest susceptibility resource depends on the spatial pattern of pest dispersal, we...

L’utilisation de pesticides et l’introduction de variétés résistantes à certains bioagresseurs (insectes, champignons, virus, bactéries) en agriculture exercent une pression de sélection sur ces populations de bioagresseurs. Au cours du temps, l’efficacité de ces technologies peut...

This presentation gives a perspective on the main findings of the economic literature dealing with pest resistance management and on questions for future research. Resistance to pest damage is embedded in some crop varieties, which thereby have an economic advantage over their conventional...

La protection de l’environnement se fait-elle automatiquement au détriment de la rentabilité des entreprises ? Cet article tend à démontrer que performance environnementale et économique ne sont pas toujours substituts mais peuvent être complémentaires pour l’entreprise. À travers...

Nous testons en laboratoire trois instruments destinés à réguler l’exploitation d’une ressource commune par des agents hétérogènes : un système de taxes et de subventions, des quotas individuels transférables et non transférables. Nous proposons un modèle dans lequel l’objectif...

The paper analyzes the welfare effects of the introduction of GMO technology into a market in which a fraction of consumers refuses to buy GMOs. Our theoretical model recognizes that segregation and identity preservation (IP) of non-GMOs may create costs for both IP producers and non-IP...

In this paper, we conduct an empirical investigation of potential adoption of herbicide-tolerant (HT) genetically modified (GM) rapeseed in France. Our aim is to study ex ante the potential impact of their adoption in France, in terms of adoption level, economic gains, and distribution of these...

We examine the optimal time-variant refuge policy to manage pest resistance to Bt crops in afinite-horizon discrete-time model. We identify analytically the intertemporal effects of refuge fields on the pest population and its susceptibility. The shape of the optimal refuge policy and whether or...
