Abstract

The issue of timing and scope of policies to manage invasive species has achieved considerable attention in the economic literature. Whereas many earlier studies compare prevention and control for a single invading species, we focus instead on the optimal balance of adaptation and control when an invasive species competes for scarce resources with a resident species. In particular, we focus on the role that species’ life history, i.e. the degree of evolutionary specialization in survival or reproduction, plays for the choice of strategy. A numerical age-structured optimization model is used for the analysis. Results show that life history is an important factor for the trade-off between direct control of the invader and adaptation of harvesting strategies for the resident species. Life history is also crucial for the trade-off between early and delayed control of the invader. When a direct control technology is not available, there are larger economic losses with a resident species specialized in survival, whereas if such technologies are available, the larger losses occur with a resident species specialized in reproduction.
