Adaptation strategies and collective dynamics of extraction in networked commons of bistable resources

Abstract When populations share common-pool resources (CPRs), individuals decide how much effort to invest towards resource extraction and how to allocate this effort among available resources. We investigate these dual aspects of individual choice in networked games where resources undergo regime s...
