| 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 find that the usual preference for market-based environmental instruments does not necessarily apply to pest resistance management. Mandatory refuges are preferred to a tax on the resistant variety for some assumption sets on heterogeneity between farms and pest dispersal distances. |

| 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 producers. Our results show how GMO-hating consumers may win or lose from the introduction of GMO technology. If IP creates costs for non-IP producers, indifferent consumers and GMO producers may be made worse off because others refuse to consume GMOs. If GMO rejection is strong, IP producers win when GMOs are introduced, even though they do not produce GMOs. |

| 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 gains between farmers and input suppliers. We use French survey data about current plant protection practices, in order to compute pesticide costs with conventional (i.e., non GM) crops for individual farms. Then, based on results of technical studies about GM variety trials in France, we compute a predicted pesticide cost with the GM variety. Next, we study adoption rates and gains or losses of farmers (adopters and non adopters) and upstream companies (sellers of... |
