The Effects of Growing Groups and Scarcity on the Use of a Common Pool Resource – a Lab-in-the-Field Experiment with Lake Victoria Fishers
通过乌干达渔民的实地实验室实验,研究资源稀缺或丰富以及用户数量增加时,公共池塘资源的使用如何变化,发现渔民在压力下不减少捕捞,导致稀缺资源被快速增长群体过度开发。
Abstract Using a lab-in-the-field experiment with Ugandan fishers, we study if and how the use of a common pool resource changes when the resource is either scarce or abundant and when the number of users increases over time. Both resource scarcity and a growing group require users to be more constrained, that is, more cooperative, in order to maintain the resource. However, the results show that fishers do not curtail their harvesting behavior under increased pressure, leading to rapid overexploitation when scarce resources are used by a growing group. This implies a particular need for sustainable management when scarce resources are exposed to in-migration.
