Members of a rock and roll band are endowed with different creativity. They match and eventually obtain credit for song writing as well as a share of the returns from sales. More creative members increase the probability of success but may also claim a larger share of the pie. In our theoretical...

Experimental and observational studies have highlighted the importance of agents being conditionally cooperative when facing a social dilemma. We formalize this mechanism in a theoretical model that portrays a small community having joint access to a common pool resource. The diffusion of norms...

Real world observations suggest that social norms of cooperation can be effective in overcoming social dilemmas such as the joint management of a common pool resource – but also that they can be subject to slow erosion and sudden collapse. We show that these patterns of erosion and collapse...

This paper examines the role of pro-social behavior as a mechanism for the establishment and maintenance of cooperation in resource use under variable social and environmental conditions. By coupling resource stock dynamics with social dynamics concerning compliance to a social norm prescribing...

This paper presents an experimental study on the ability of human groups to escape the tragedy of the commons through institutional change. It shows that the groups identify institutional change as a means of resolving social dilemmas and are ready to apply it even if the change requires an...

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...

Ambiguous concepts blur analytical and policy prescription clarity. In the literature on Natural Resources it would be difficult to find a concept as misunderstood as commons. This paper clarifies this confusion and establishes an adequate conceptualisation. A typology of property-rights regimes...

Tariff is a trade measure with both of the trade and environmental effects. This article analyzes the interaction between the tariff rate and the short and long run environmental qualities of imperfectly substitutive imported goods. In the first part, we analyze the effect of changing the tariff...
