چکیده

We explore the external validity of a common pool resource (CPR) laboratory experiment. The experimental subjects were artisanal fishers who exploit benthic resources on the coast of Chile. A first set of subjects was recruited from fishers’ unions that comanage their resources through territorial user right areas. These unions differ in their performance, which is largely the outcome of the cooperative efforts of their members. A second set of subjects was recruited among nonunionized fishers who do not participate in the comanagement system. They fish exclusively in open-access areas and barely cooperate in their fishing. Membership of a union and the union’s performance in comanagement were related to the subjects’ behavior in the laboratory. In the CPR experiment, members of high-performance unions showed high cooperation with each other, while members of low-performance unions cooperated significantly less. Nonunionized fishers did not cooperate at all. We also explored how the weak external enforcement of an individual quota can trigger changes in behavior, what we refer to as internalizing the norm. Only the members of high-performance unions internalized the norm. They refrained from overfishing until the end of the game, even though the sanction for exceeding the quota was not strong enough to be dissuasive from the point of view of pure self-interest. This study provided insight on the experimental analysis of cooperation in artisanal fisheries and suggested that the capacity to internalize norms is important to the sustainable exploitation of artisanal fisheries common pool resources. RESUMEN. Exploramos la validez externa de un experimento de laboratorio con un recurso de uso común. Los sujetos del experimento han sido pescadores artesanales que explotan recursos bentónico en la costa de Chile. Un primer grupo de personas proviene de organizaciones de pescadores que utilizan sistemas de co-manejo explotando estos recursos a través de derechos territoriales de uso. Un segundo grupo de pescadores incluidos en este experimento no pertenecían a organizaciones de pescadores y tampoco participaban en sistemas de co-manejo, pescando de forma exclusiva bajo un régimen de acceso abierto y rara vez cooperan entre ellos. Este trabajo realiza un análisis comparativo entre el desempeño en co-manejo entre estas diferentes organizaciones de pescadores y el comportamiento colaborativo de los pescadores. Los resultados indican que los pescadores miembros de organizaciones con elevado desempeño presentan un alto grado de cooperación entre ellos, mientras que aquellos donde se observa bajo desempeño su nivel de cooperación es también significativamente más reducido. El trabajo también demuestra que los pescadores que no forman parte de organizaciones de pescadores tampoco mostraron ningún tipo de cooperación. Asimismo, tamibén investigamos cómo un débil cumplimiento externo de la normativa en relación a las cuotas de capturas puede provocar cambios en el comportamiento de los pescadores, entendido aquí como internalización de las normas. Sólo los miembros de organizaciones con un Elevado desempeño demuestran haber internalizado las normas. Se abstuvieron de continuar sobrepescando hasta el final de juego a pesar de que la sanción prevista por exceder la cuota no era lo suficientemente disuasoria desde la perspectiva de su propio interés. Este estudio aporta nueva luz sobre el análisis experimental de la cooperación en pesquerías artesanales, y sugiere que la capacidad de internalizar las normas es relevante para la explotación sostenible de recursos comunes en pesquerías artesanales.

Exploitation rates of two benthic resources across management regimes in central Chile: Evidence of illegal fishing in artisanal fisheries operating in open access areas

There is an urgent need to quantify the impacts of artisanal fisheries and define management practices that allow for the recovery and conservation of exploited stocks. The extent of illegal catch is particularly critical as a driver of overexploitation in artisanal fisheries. However, the lack of data at proper spatial scales limits the evaluation of illegal fishing and effectiveness of manage...

Optimum Fisheries Management under Climate Variability: Evidence from Artisanal Marine Fishing in Ghana

In most developing coastal 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 rising coastal temperature and its variance, which could impact the environmental carrying capacity of the fish stock. This study investigates the effect of ...

Time Preferences and Natural Resource Extraction Behavior: An Experimental Study from Artisanal Fisheries in Zanzibar

Natural resource users face a trade-off between present and future consumption. Using harmful methods or extracting unsustainably, lowers future consumption. Therefore, it is reasonable to posit that people with higher time preferences extract more as compared to people with lower time preferences. The present study combines experimental methods and questionnaire data in order to understand the...

Why Natural Disasters are a Disaster in Common Property Resources

Developing countries tend to suffer the most from natural disasters, but the mechanisms underlying this outcome are poorly understood. I postulate that the lack of strong and well defined property rights for renewable resources is a key factor increasing the impacts of disasters. Using a theoretical model for renewable resource extraction with irreversible investment, I show that common propert...
