Within and Between Group Variation of Individual Strategies in Common Pool Resources: Evidence from Field Experiments

No 2006-4, Working Papers from University of Massachusetts Amherst, Department of Resource Economics

Abstract: With data from framed common pool resource experiments conducted with artisanal fishing communities in Colombia, we estimate a hierarchical linear model to investigate within-group and between-group variation in individual harvest strategies across several institutions. Our results suggest that communication serves to effectively coordinate individual strategies within groups, but that these coordinated strategies vary considerably across groups. In contrast, weakly enforced regulatory restrictions on individual harvests (as well as unregulated open access) produce significant variation in the individual strategies within groups, but these strategies are roughly replicated across groups so that there is little between-group variation.
