CREDIBILITY OF LINEAR EQUILIBRIUM STRATEGIES IN A DISCRETE-TIME FISHERY MANAGEMENT GAME

In this article we consider a two-country dynamic game model of whalin g in discrete time. We assume that the countries have exact informatio n, with one-period time delay, about each other's whaling efforts as m easured by the number of vessels involved in whaling. It is shown how strategies that linearly depend on the whaling effort of the other cou ntry can be used to support a given Pareto-optimal agreement so that t here will not be a temptation for unilateral deviation from the agreed decision. The credibility of these cooperative equilibrum strategies is discussed.
