Abstract

Risk of stock collapse is a genuine motivation for cooperative fisheries management. We analyse the effect of an endogenously determined risk of stock collapse on the incentives to cooperate in a Great Fish War model. We establish that equilibrium harvest strategies are non-linear in stock and find that Grand Coalitions can be stable for any number of players if free-riding results in a total depletion of the fish stock. The results thus show conditions under which a Great Fish War becomes a Great Fish Pact. However, this conclusion no longer holds upon dropping the standard assumption that payoffs are evaluated in steady states. If payoffs in the transition between steady states are included, the increased incentives to deviate offset the increased benefits from cooperation due to the presence of endogenous risk and the Great Fish Pact returns to being a Great Fish War.
