Lobbying, Trade and Renewable Resource Harvesting
Lobbying, Trade and Renewable Resource Harvesting Richard Damania and E. Barbier The over-exploitation of renewable resources has intensified international concerns over the management of these resources. This has prompted calls for the use of international policy interventions such as trade sanctions and contingent transfers, to encourage sustainable resource management practices in these coun...
متن کاملThe Option Value of Harvesting a Renewable Resource
We analyze multi-period harvest problems for a renewable resource under biological uncertainty when harvesting is size-dependant. First, we show that the decision to harvest can be modeled as a real option and we derive analytical expressions for the value of the resource stock and the mean time between harvests, with and without uncertainty. We then illustrate numerically how uncertainty affec...
متن کاملOptimal harvesting of stochastic spatial resources
We characterize the optimal harvest of a renewable resource in a generalized stochastic spatially explicit model. Despite the complexity of the model, we are able to obtain sharp analytical results. We find that the optimal harvest rule in general depends upon dispersal patterns of the resource across space, and only in special circumstances do we find a modified golden rule of growth that is i...
متن کاملModelling the Dynamics of a Renewable Resource under Harvesting with Taxation as a Control Variable
The present paper describes a model of resource biomass and population with a non-linear catch rate function on resource biomass. The harvesting effort is assumed to be a dynamical variable. Tax on per unit harvested resource biomass is used as a tool to control exploitation of the resource. Pontryagin’s Maximum Principle is used to find the optimal control to maintain the resource biomass and ...
متن کاملOptimal Spatial Harvesting Strategy and Symmetry-Breaking
A reaction-diffusion model with logistic growth and constant effort harvesting is considered. By minimizing an intrinsic biological energy function, we obtain an optimal spatial harvesting strategy which will benefit the population the most. The symmetry properties of the optimal strategy are also discussed, and related symmetry preserving and symmetry breaking phenomena are shown with several ...
