Tariffs, Income Distribution and Welfare in a Small Overlapping-Generations Economy
分析小型代际重叠经济中进口关税的福利影响，重点研究关税导致的收入再分配如何决定福利的时间路径，并给出关税在贸易条件不变时提高短期和长期福利的充分条件。
This paper analyzes the welfare implications of an import tariff for a small overlapping-generations economy. The study analyzes the role of income redistribution, induced by the imposition of a tariff, in the determination of the time path of welfare levels. It is shown that despite homotheticity, the (implicit) pattern of distribution of tariff revenues is an integral and prominent component in the assessment of the welfare consequences of a tariff. The analysis provides sufficient conditions under which a tariff increases short-run as well as long-run welfare despite the absence of changes in the terms of trade.
