| Inbred line seed producers face competition from their own consumers: farmers who save part of their harvest can costly self-produce. To reduce this competition, seed producers can switch to non-durable hybrid seed production. In a two-period model, we investigate what is the impact of crop durability on self-production, pricing strategies and switching decision. We first study the pricing decisions and switching decisions of an inbred line seed monopoly. Then, we analyze how the monopoly's behavior is affected by the entry of a hybrid seed producer. We also examine how the introduction of royalties on farmers who self-produce improves efficiency. Our main finding is that, for some constellation of costs, an inbred line seed monopoly has an incentive to... |

| 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. |
