A Computable Game Theoretic Approach to Modelling Competitive Fishing

Abstract

A fishery is considered in which the young are harvested by one nation, and the adults by another. The harvests are sold on separate markets. Finding the optimal strategies of the two nations is treated as a problem in dynamic non-cooperative game theory. While in most other models players make decisions simultaneously at each stage, in this model each player makes his decision separately in time, knowing the action of the previous player. The model is applied to the southern bluefin tuna fishery which is jointly exploited by Australia and Japan. The results of non-cooperative and cooperative strategies are compared.Environmental Economics and Policy, International Development, International Relations/Trade, Resource /Energy Economics and Policy,
