This paper addresses the following hitherto unstudied question in renewable resource management: How should a resource manager set the temporal control optimally for renewable resources such as rangelands and fisheries that are managed with spatial and temporal controls? We use a dynamic and...

Biodiversity is often adversely affected by human activities. This reduces social welfare but may be external to private economic decisions. Consequently, these external effects on biodiversity need to be considered explicitly in economic models, which is only partly reflected in the literature....

The evolution of renewable resources is characterized in many cases by different time scales where some state variables such as biomass, may evolve relatively faster than other state variables such as carrying capacity. Ignoring this time scale separation means that a slowly changing variable is...

A key goal of renewable resource managers in developing countries is to take actions to ensure that the resource being managed stays away from irreversible or crisis states in which it provides neither consumptive nor non-consumptive services to humans. However, despite a manager's best efforts,...

We present a simple general equilibrium model of renewable resource and population dynamics that might explain the rise and fall of Easter Island's civilization. The model generates a system similar to the Lotka-Volterra predator-prey model. In our formulation man is the predator and the...

We analyze how the threat of a potential future regime shift affects optimal management. We use a simple general growth model to analyze four cases that involve combinations of stock collapse versus changes in system dynamics, and exogenous versus endogenous probabilities of regime shift. Prior...
