Regulation and Evolution of Compliance in Common Pool Resources

The paper jointly models the evolution of compliance with regulation and the evolution of a CPR stock, by combining replicator dynamics describing compliance with harvesting rules, with resource stock dynamics. This evolutionary approach suggests that coexistence, in long run equilibrium, of both cooperative and non-cooperative rules under regulation is possible. Stock effects on profits and a certain structure of auditing probabilities could imply the emergence of a limit cycle in areas of low stock levels, as an equilibrium outcome for compliance and the biomass stock. It might be easier for the regulator to obtain full compliance under precommitment to fixed auditing probabilities.
