Potential Irreversible Catastrophic Shifts of the Assimilative Capacity of the Environment

摘要: Pollution accumulation may result in more or less severe losses of natural self-cleaning capacities. We study a polluting resource management problem submitted to potential shift from high low pollution self-regeneration regime be crossed some critical stock threshold. first describe the optimal exploitation policy absent When at threshold, society has two options: either stabilizing level avoid loss capacity deliberately cross threshold and switch regeneration regime. show under fairly general assumptions that there exists unique such thresholds located below this will induce while above it imply maintaining forever. characterize policies these scenarios triggering requires an upward jump consumption rate switching time.
