In this paper a dierential game model of renewable resource ex- ploitation is considered in which rms compete in exploiting a com- mon resource in a Bertrand price-setting game. The model character- izes a situation in which rms extract a common renewable resource which after harvesting may be...

This paper describes the application of the participatory diagnosis and adaptive management (PDAM) framework to analyze the governance of small-scale fisheries and the potential for adopting the Ecosystem Approach to Fisheries (EAF) in Misamis Occidental, Philippines. Using the Rapid Appraisal...

This paper investigates the role played by cooperation for the sustainable harvesting of an ecosystem. To achieve this, a bio-economic model based on a multi-species Gompertz dynamics with interspecific relationships and multi-agent catches is considered. A comparison between the non...

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...

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...

La gestión eficiente de ciertos recursos renovables caracterizados por la propiedad común y el libre acceso ha estado mediatizada por la denominada «Tragedia de los Comunes». La literatura pionera en este campo enfatizaba la necesidad de un marco regulatorio que superara esta tendencia hacia...

The multispecies fisheries management looks at a bigger picture in addressing the long-term consequences of present decisions. This implies an ecosystem management that includes a number of species and their physical, biological and economic interactions. These interactions make the growth of...

This study examines the spatial nature of optimal bioinvasion control. We develop a spatially explicit two-dimensional model of species spread that allows for differential control across space and time, and we solve for optimal spatial-dynamic control strategies. We find that the optimal...

When every individual's effort imposes negative externalities, self-interested behavior leads to socially excessive effort. To curb these excesses when effort cannot be monitored, competing output-sharing partnerships can form. With the right-sized groups, aggregate effort falls to the socially...

Two agents possess the fishing rights to a lake. Each period they have two options, to catch without restraint, e.g., to use a fine-mazed net, or to catch with some restraint, e.g., to use a wide-mazed net. The use of a fine-mazed net always yields a higher immediate catch than the alternative....
