- 摘要：We extend the traditional G-S model of open access by defining a non-concave harvesting function. We demonstrate the possible existence of multiple equilibria and perverse comparative statics and show that small changes in the underlying economic parameters may trigger large jumps in species' abundance. Finally, we briefly discuss implications for management. © 2002 Elsevier Science B.V. All rights reserved.
