THE ROLE OF COMMUNICATION IN RESOLVING COMMON DILEMMAS - EXPERIMENTAL-EVIDENCE WITH HETEROGENEOUS APPROPRIATORS

Communication has been shown to be an effective mechanism for promoting efficient resource use in homogeneous common-pool resource settings. Communication allows appropriators the opportunity to agree on an aggregate appropriation target and coordinate over the selection of input allocation rules. When appropriators are identical, these rules result in identical input allocations, which facilitates cooperation. We examine the robustness of communication as an efficiency-enhancing mechanism in settings where appropriators differ in input endowments. This heterogeneity creates a distributional conflict over access to common-pool resources. This conflict can cause self-governance to fail. We present findings from a series of experiments where heterogeneous endowments are assigned: (1) randomly, and appropriators have complete information, (2) through an auction, and appropriators have complete information, and (3) randomly, and appropriators have incomplete and asymmetric information. These findings are contrasted with rules from CPR field settings. (C) 1994 Academic Press, Inc.
