Abstract. This paper provides estimates of the potential gains to the Asia Pacific region from completely freeing merchandise trade globally and from partial liberalizations that might emerge from the Doha Round. Particular attention is given to agriculture, where the majority of the gains would arise. The results suggest that moving to free global merchandise trade would boost real incomes in the Western Pacific proportionately more than in other regions. The Doha partial liberalization scenarios considered would move the world only a small way towards complete free trade, but inreasingly so the more developing countries themselves are willing to open up.
