The effects of random environmental impacts on optimal exploitation of a fish population are investigated using both optimization and simulation, based on a discrete-time age-structured bioeconomic model. The optimization problem is solved as a non-linear programming problem in GAMS. First, a...

In standard models of spatial harvesting, the resource is distributed over the complete domain and the agent is able to control the harvesting activity everywhere all the time. In some cases though, it is more realistic to assume that the resource is located at a single point in space and that...

Fisheries management must manage people in order to manage fish. In this sense, understanding fishing behavior is the … cornerstone of effective fisheries policy. However, the latency of fish stocks is a major obstacle in empirical studies. This …

In most coastal developing countries, the artisanal fisheries sector is managed as a common pool resource. As a result …, such fisheries are overcapitalized and overfished. In Ghana, in addition to anthropogenic factors, there is evidence of …

In many spatial resource models it is assumed that the agent is able to determine the harvesting activity over the complete spatial domain. However, agents frequently have only access to a resource at particular locations at which the moving biomass, such as fish or game, may be caught or...

We explore the effects of free trade in a renewable natural resource between two countries in the presence of incomplete property rights. While resource management by one country may benefit one or both trading partners, we demonstrate that resource management by only one of the partners may...

We consider a robust control model for a spatially distributed commercial fishery under uncertainty, and in particular a tracking problem, i.e. the problem of robust stabilization of a chosen deterministic benchmark state in the presence of model uncertainty. The problem is expressed in the form...
