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...

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...

This paper presents a theoretical economic model assessing the effects of the level of mandatory genetically modified (GM) / non-GM coexistence regulations on market and welfare outcomes. We assume vertical differentiation of GM and non-GM goods on the consumer side. Producers are heterogeneous...

In the framework of a two-country, two-good partial equilibrium model where one of the commodities (the bulk commodity) is an intermediate input in the production of the second good (the processed good), we assume that the government wishes to transfer income to both bulk commodity and processed...
