| Economic Experimental Games (EEGs), focused to analyze dilemmas associated with the use of common pool resources, have shown that individuals make extraction decisions that deviate from the suboptimal Nash equilibrium. However, few studies have analyzed whether these deviations towards the social optimum are affected as the stock of resource changes. Performing EEG with local fishermen, we test the hypothesis that the behavior of participants differs under a situation of abundance versus one of scarcity. Our findings show that under a situation of scarcity, players over-extract a given resource, and thus make decisions above the Nash equilibrium; in doing so, they obtain less profit, mine the others-regarding interest, and exacerbate the tragedy of the... |

| Economic Experimental Games (EEG) have challenged the theoretical prediction showing that individuals balance own and collective interests when making decisions that deviate away from suboptimal Nash equilibrium. However, few studies have analyzed whether these deviations from Nash equilibrium towards social optimum are affected as the stock of resource changes. Performing EEG with real fishers we test the hypothesis that behavior of participants –measured as relative deviations from Nash equilibrium- differs under a situation of abundance versus a situation of scarcity. The design of our EEG is based on a profit maximization model that incorporates intertemporal effects of aggregated extraction. Our findings show that in a situation of scarcity, players... |

| The National Natural Park "Corales del Rosario y San Bernardo", located in the Caribbean Sea, is one of the most important parks in Colombia since it hosts high biological biodiversity, receives more tourists than any other natural park in the country and provides sustenance to several communities settled in and around it. However, lack of governance and incompatibility of incentives among authorities, communities and visitors threaten its conservation and sustainability. Using experimental economic games with fisherman communities, we tested different rules related with the management of natural resources in the protected area. In addition to standard rules of communication and external regulation, we tested a rule called co-management, in which we... |
