It is shown in a North-South world where the South has to cooperate for efficient pricing policy. In addition to the complexities of interactions between three countries, a dynamic game approach leads to the usage of numerical methods in this paper. We used a new algorithm based on adaptive search procedure called genetic algorithm to optimize strategies for three-person discrete dynamic games. Welfare implications are also addressed.EnglishGenetic algorithmDiscrete dynamic gamesThree-country tradeCoalition.Article10.1016/0898-1221(96)00134-41873-7668
