In deciding to keep or fell a forest stand given its age, the risk of loss of timber through wildfire is an important consideration. If trees also have value from sequestration of carbon, another effect of fire is the unplanned loss of stored carbon. Factors affecting the decision to keep or...

Invasive species eradication programs can fail by applying management strategies that are not robust to potentially large but non-quantified risks. A more robust strategy can succeed over a larger range of possible values for non-quantified risk. This form of robustness analysis is often not...

An optimising model is developed to determine the .sequence of total allowable catches of western mackerel which would result in the maximum present value of the stream of annual rents. It is found that the optimal steady state fishing mortality would be one half to one third of recent levels....

Abstract It is pervasively argued that the equilibrium outcome for an open-access fishery in which harvesting cost is inversely related to fish stock is inefficient, with complete dissipation of within-season rents. However, some argue instead that within-season rents are maximised. Conditions...
