Most renewable biotic resources are subject to random variability in natural growth. We investigate the implications of such variability for long-term management by a risk averse social planner, who maximizes expected long-run utility. In the canonical model of a stochastic fishery, we show that the optimal level of harvesting effort need not necessarily be reduced by variability in stock growth. However, optimal effort is reduced if variability of growth increases for smaller base populations, as suggested in the ecology literature.

生态黄金法则

大多数可再生生物资源在自然生长中会随机变化。我们调查了这种可变性对风险规避的社会规划者的长期管理的影响，该规划者将预期的长期效用最大化。在随机渔业的典范模型中，我们表明，种群增长的可变性不一定会降低最佳的捕捞努力水平。但是，如生态文献所述，如果对于较小的基本种群而言，如果增长的可变性增加，则会减少最佳努力。
