Strict Pareto-Improving Multilateral Reforms of Tariffs
研究从关税扭曲的国际贸易均衡出发，多边逐步改革关税（及其他贸易税和补贴）的福利效应，给出了存在严格帕累托改进的多边关税改革（伴随国际收入转移）的充要条件，并应用于比例削减关税、降低最高从价税率等具体方案。
Starting from a tariff-distorted equilibrium of international trade, the authors examine the welfare effects of a gradual multilateral reform of tariffs (and other trade taxes and subsidies). Necessary and sufficient conditions for the existence of strict Pareto improving multilateral (differential) tariff reforms, accompanied by international transfers of income, are obtained. These results are then applied to various concrete tariff reform proposals such as proportional reductions in tariffs and the reduction of the highest ad valorem tariff rates. Some of the authors' theorems extend the generality of previously obtained results and some new tariff reform proposals are also made. Copyright 1991 by The Econometric Society.
