Abstract: | I study the effect of a small import tariff imposed by the government of an economic union of countries upon the welfare of workers in its member countries. I examine whether workers in some member countries are made worse off by the tariff imposition. Special attention is paid to the population distribution within the union and the geographical relationship among trading countries. I also examine whether the tariff imposition reduces the gaps between the welfare levels of workers in the member countries. JEL Classification Numbers: F13, R13. |
