Abstract

We conducted a dynamic common pool resource experiment and found large differences among groups in the total benefits (surplus) obtained from the resource. To shed light on the factors underlying the differences, we characterized individual appropriation decisions as irresponsible, sustainable, or constructive, and defined a measure of the intensity of such actions. We then examined the relationships between group-level success and the frequency and intensity of the individual actions, finding that the average intensity of irresponsible actions was the best predictor of group success. We interpreted this as suggestive evidence that policies aimed at preserving and maximizing the benefits of renewable resources should above all else aim to reduce the intensity of irresponsible actions.

Summary

Introduction

Common pool resource experiments tended to implement repeated, static games in which the size of the resource stock was the same in every round [1,2,3]. The management of many common pool resources (especially renewable ones, such as fish) is inherently dynamic. Researchers have begun using resource stocks that evolve over time [4,5,6,7,8,9,10]. The focus is often on the exogenous factors affecting group-level outcomes rather than on individual decisions.. We focused on individual actions by characterizing them based on how they affect the size of the resource stock. We characterized actions as irresponsible, sustainable, or constructive, and defined a measure of their intensity. We examined how group earnings related to the frequency and intensity of the actions, finding that the average intensity of irresponsible actions is the best predictor of group earnings
