Public disclosure of players’ conduct and common resources harvesting: experimental evidence from a Nairobi slum

We evaluate the effect of information disclosure (feedback on individual contributions and payoffs) on players’ behavior in a multi-period common pool resource game experiment run in an area of notably scarce social capital, such as the Nairobi slum of Kibera. We document that cooperation significantly declines over rounds when such information is revealed. Our results are consistent with the Ostrom (2000) hypothesis that, in the absence of formal punish ment rules, the availability of information about individual behavior makes common resource management more difficult and tragedy of the commons easier.
