In this paper we measure the recreational economic benefits of the for-hire recreational fishery in the coastal region of North Carolina. We estimate a single trip random utility model for primary purpose and secondary purpose anglers with data from a field survey of charter and head-boat...

This paper develops and applies a new method for estimating the economic benefits of an environmental amenity. The method fits within the household production framework and is based upon the notion of estimating the derived demand for a privately traded option to utilize a freely-available...

Travel cost recreation demand models stem from a simple, but penetrating, insight. Consumption of an outdoor recreation site's services requires the user to incur the costs of a trip to that site. Travel costs serve as implicit prices. These costs reflect both people's distances from recreation...

Catastrophic risk is currently a hotly debated topic. This paper contributes to this debate by showing two results. First it shown that the value function in dynamic optimization can have an infinite derivative at some point even if the model specification has functional forms that are finite...

In commercial fisheries, stock collapse is an intrinsic problem caused by overexploitation or due to pure stochasticity. To analyze the risk of stock collapse, we apply a relatively simple Monte Carlo approach which can capture complex stock dynamics. We use an economic model with downward...

Marine Protected Areas are considered as a hedging tool against some of the uncertainties that trouble many fisheries today. Such tools are always connected with a cost; a premium. An optimal harvest rule is combined with a protected area to manage a fishery. The model ignores uncertainty, and...

We consider an infinite horizon optimization problem with arbitrary but finite periodicity in discrete time. The problem can be formulated as a fix-point problem for a contraction operator, and we provide a solution scheme for this class of problems. Our approach is an extension of the classical...

This study presents a multispecies stochastic model. The model suggests optimal fishing policy for two species in a three species predator prey ecosystem in the Barents Sea. We have employed stochastic dynamic programing to solve a three dimensional model, where catch is optimized by a...

This paper analyzes the optimal management of a natural resource that can shift between different dynamics at random times. Using a classical linear control model I investigate how the switching behavior influences the optimal extraction of the resource. I use exogenous sea-surface temperature...
