Domestic Distortions and International Trade
提出用距离函数方法衡量国内扭曲的贸易政策等价物，即贸易限制指数，该指数等于与国内税收和补贴模式福利等价的统一关税，并应用于墨西哥农业自由化分析，对贸易谈判者和实证研究者有参考价值。
In this paper, the authors develop techniques for measuring the trade policy equivalent of domestic distortions using a distance function approach. Their measure, the trade restrictiveness index, is shown to equal the uniform tariff that is welfare equivalent to a given pattern of domestic taxes and subsidies. The authors extend the index to incorporate taxes in markets for nontraded goods and factors of production and illustrate its operationality with an application to liberalization in Mexican agriculture. They conclude that their index has considerable potential in empirical work and as an aid to trade negotiators.
