We show that whether intensive or extensive farming is most beneficial to biodiversity depends on the equilibrium of agricultural markets. With higher production costs, extensive farming tends to be more beneficial to biodiversity than intensive farming, except when there is a very high degree...

We show that between intensive and extensive farming, the production method most beneficial to biodiversity depends on the equilibrium of agricultural markets. All other things equal, as long as demand reacts to prices and extensive farming has higher production costs, extensive farming tends to...

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...

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...

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...
