Procreation, Fishing, and Hunting: Renewable Resources and Dynamic Planar Systems
提供分析性和图形化方法，研究可再生资源经济学的动态平面系统，包括全局动态、驻点存在性和局部稳定性，并应用于人口与环境质量、鱼类资源开发以及更新世灭绝与农业起源的经济学问题。
Abstract Many problems in the economics of renewable resources can be put in the form of a dynamic planar system. This paper provides analytic and graphical methods for the study of the global dynamics, existence of stationary points, and local stability properties of such systems, and applies these methods to problems of (1) population and environmental quality; (2) exploitation of a stock of fish; and (3) the economics of the pleistocene extinctions and the origins of agriculture.
