Credibility of linear equilibrium strategies in a discrete time fishery management game

In this article the authors consider a two-country dynamic game model of whaling in discrete time. They assume that the countries have exact information, with one-period time delay, about each other’s whaling efforts as measured by the number of vessels involved in whaling. It is shown how strategies that linearly depend on the whaling effort of the other country can be used to support a given Pareto-optimal agreement so that there will not be a temptation for unilateral deviation from the agreed decision. The credibility of these cooperative equilibrium strategies is discussed.
