摘要：Case-study analysis shows that long-lasting social–ecological systems have institutionalarrangements regulating where, when, and how to appropriate resources instead of how much. Those casestestify to the importance of the fit between ecological and institutional dynamics. Experiments areincreasingly used to study decision making, test alternative behavioral models, and test policies. In typicalcommons dilemma experiments, the only possible decision is how much to appropriate. Therefore,conventional experiments restrict the option to study the interplay between ecological and institutionaldynamics. Using a new real-time, spatial, renewable resource environment, we can study the informalnorms that participants develop in an experimental resource dilemma setting. Do ecological dynamicsaffect the institutional arrangements they develop. We find that the informal institutions developed onwhen, where, and how to appropriate the resource vary with the ecological dynamics in the differenttreatments. Finally, we find that the amount and distribution of communication messages and not the contentof the communication explains the differences between group performances
