Developing Countries and the Gains from Regionalism: Links between Trade and Farm Policy Reforms in Mexico
用多国可计算一般均衡模型模拟北美自由贸易协定，发现墨西哥只有在同时消除国内农业扭曲时才能获益，此时农业的配置效率收益足以抵消因初始关税较高导致的贸易条件损失。
Abstract We use a multi‐country computable general equilibrium (CGE) model with agricultural policy details to simulate the effects of North American Free Trade Agreement (NAFTA). We find that Mexico gains from NAFTA only when it also removes domestic distortions in agriculture. In that case, agriculture can generate allocative efficiency gains large enough to offset the terms of trade losses that arise because Mexico has higher initial tariffs than its NAFTA partners. When an RTA forces a developing country to reform its domestic distortions that are linked to trade restrictions, it becomes a building block toward multilateralism.
