Landing Fees versus Fish Quotas
研究了在实现特定产卵量目标时，上岸费与配额控制两种政策哪种更有效率，基于年利润标准，通过模拟比较了在种群估计不精确、鱼类可获得性变化和价格随机等不确定性下的表现。
<i>The relative efficiency of landing fees versus quota controls to achieve given escapement levels is examined. The criterion is profit per year over a given time horizon. The model employed is a discrete version of the logistic model where growth is influenced by a random variable. Simulations are used to compare landing fees and quota controls under imprecise stock estimates, variable availability of fish, and random fish prices. While ecological uncertainty combined with imprecise stock estimates favors fee control, as shown by Weitzman, the opposite can be the case under uncertainty about the availability of fish or fish price.</i>
