This paper proposes using a control function to correct for endogeneity in recreation demand models. The control function approach is contrasted with the method of alternative specific constants (ASCs), which has been cautiously promoted in the literature. As an application, we consider the case...

En el marco del diseño e implementación del subsistema de Áreas Marinas Protegidas (SAMP) en Colombia, se realiza una valoración económica (VE) comprehensiva que utiliza variados métodos e incluye diferentes agentes que van desde comunidades locales hasta compradores de créditos de...

In an insular region, such as the Archipelago of San Andres, Providencia and Santa Catalina, environmental issues tend to sharpen. As result, its environmental management is different compared to other areas of Colombia, since the vast majority of its territory corresponds to marine surface....

Resumen El establecimiento de Áreas Marinas Protegidas se ha definido como la principal herramienta para la protección y conservación de los ecosistemas marinos y costeros. Dentro de los beneficios que ofrece el establecimiento de estas áreas se encuentran aumentos en la biodiversidad de...

While public investment in conservation such as the Conservation Reserve and Wetlands Reserve Programs have improved the environmental state of the lands, they have not provided an institutional means for production and profit expansion for the same acreage. This type of public investment places...

Forest management aims at building ecological networks that minimize the impacts on timber production. We formalize the construction of ecological networks in forest environments as the optimal control dynamic graph-theoretic problem. The ecological network is based on a set of bioreserves and...

Resumen Las áreas marinas protegidas son reconocidas en la actualidad como una alternativa de conservación de los ecosistemas marinos. Aunque la figura de protección reduce el área disponible para la actividad pesquera, se ha documentado que la misma puede convertirse en una fuente de...

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...

This paper develops an optimal harvesting model for the wild Atlantic salmon (Salmo salar), where various age classes of the population are included. It is shown that the marginal value–fecundity relationship of the spawning population, comprising young and old fish, is crucial for the optimal...

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...
