We examine behavior in one-shot appropriation games with deterministic and probabilistic degradation externalities, where the marginal net benefit from appropriation is endogenous, dependent on individuals' expectations of group appropriation. The experimental design involves a menu of games...

This study presents experimental results on the role that non-binding pledges have on the ability of resource users to manage the threat of probabilistic group damages in two separate environments. First, an environment where agents can work collectively to try to mitigate the root cause of the...
