Abstract This paper studies the behavior of Pacific-Colombian fishermen in a Common-Pool Resource game. The results show that decision-making depends on fishermen’s schooling, sex and last round payoffs. Focusing on individual information, we observe that human capital, measured in years of schooling, has a significant effect on decision-making. Specifically, players with higher schooling adjust their decisions towards on lower levels of harvest, leading closer to the cooperative solution. This behavior could be explained by the better-educated subjects’ improved understanding of the information available to them and possible coordination of efforts due to TURF-based management in the zone.
