摘要

The production of natural resource-based commodities is frequently affected by environmental uncertainty and the strategic response of producers to uncertainty. We ask when uncertainty induces cooperation. Using a model of Cournot competition under environmentally induced price uncertainty, we consider the conditions under which cooperation is favored over defection. We find that the probability of cooperation depends on the length of the time period over which production levels are adjusted to price shocks. When uncertainty is low, the probability of cooperation is monotonically increasing in the length of this adjustment period. When uncertainty is high, the probability of cooperation initially increases as the adjustment period lengthens, but beyond some threshold starts to fall. In this case, the expected outcome is defection. We consider the broader implications of these findings.
