The Dynamics of an Open Access Fishery
研究了一个开放获取渔业的离散时间非线性确定性模型，分析了1963-1977年北海鲱鱼的开发，发现1977年渔业关闭避免了资源灭绝。
A discrete-time, nonlinear, deterministic model for an open-access fishery is developed and the equilibrium is characterized. The open- access exploitation of North Sea herring during the period 1963-77 is analyzed. Alternative production functions are considered and estimated for the Norwegian purse seine fishery. The bionomic equilibrium and approach dynamics are presented when prices and costs are changing. The results indicate that the resource stock was saved from possible extinction by the closure of the fishery at the end of the 1977 season.
