Charting the pacific: an empirical assessment of integration initiatives

Trade negotiations after Uruguay may well be dominated by the Pacific Rim, where two free trade areas (ASEAN Free Trade Agreement, or AFTA; and North American Free Trade Agreement, or NAFTA) already exist and larger agreements are under active discussion (involving the Asia Pacific Economic Cooperation, or APEC, area and an East Asian Economic Group). This article analyzes several initiatives using a simple global general equilibrium model that incorporates conventional welfare gains as well as benefits derived from firm level economies of scale, induced changes in foreign investment, and dynamic increases in productivity. Broad Pacific liberalization—i.e., East Asia, North America, and Australasia—is shown to be superior for each participant to liberalization limited to individual countries or East Asia, but not by much. Most favored nation liberalization is shown to be superior for each participant to preferential liberalization—if the actor is East Asia, but not the Pacific as a whole. These estimates will need to be refined, but they suggest that the benefits from Pacific liberalization could exceed $100 billion per year.
