Since the pioneering work of Gordon (1954), many bioeconomic models for the description of the commercial exploitation of common property renewable resources, such as fisheries, have stressed the problem known as ‘the tragedy of the commons’ (Hardin, 1968; see also Clark, 1990). This problem can be basically identified with a prisoner’s dilemma (see for example, Mesterton-Gibbons, 1993) because...

There is a growing focus around the world on marine spatial planning, including spatial fisheries management. Some spatial management approaches are quite blunt, as when marine protected areas (MPAs) are established to restrict fishing in specific locations. Other management tools, such as zoning or spatial user rights, will affect the distribution of fishing effort in a more nuanced manner. Co...

Strategies for controlling invasive species can be aimed at any or all of the stages in the life cycle. In this paper, we show how to combine biological data on population dynamics with simple economic data on control costs options to determine the least costly set of strategies that will prevent an established invader from continuing to increase. Based on biological data alone (elasticities of...
