Look at the Canada Tariff Finder, a free tool that allows Canadian exporters to find customs duties applicable to a given commodity in a foreign market. However, this distinction between free trade area, customs union, common market, economic and monetary union and political union does not reveal much about the character of a project of individual regionalisation. Mr Plehwe opposes such a multi-level model: “In addition to global interests, the problems of regional integration must be taken into account over the internal problems of the regions, in order to be able to take into account the basis of the specific intensity and the character of regionalisation”. (Plehwe 2000: 9). The reasons for the implementation of a regionalization project, its position on the world market and the internal balance of power are excluded from this model. However, a distinction is useful for determining the intensity of regionalization, since the intensity of regional integration projects always has an internal impact on the different nations in which certain reforms are implemented. However, a free trade agreement creates not only internal pressures, but also pressure for compliance with other nations or regions. The value of free trade was first observed and documented in 1776 by Adam Smith in The Wealth of Nations writing: Free trade policy was not so popular with the general public. The main problems are unfair competition from countries where falling labour costs reduce prices and lose well-paying jobs to producers abroad.
Few topics separate economists from the general public as much as free trade. The research findings indicate that economists at U.S. university faculties are seven times more likely to support free trade policy than the general public. In fact, the American economist Milton Friedman said, “The economic profession almost agreed on the desire for free trade.” The benefits of free trade were outlined in On the Principles of Political Economy and Taxation, published in 1817 by the economist David Ricardo. Narr/Schubert emphasize the search for cooperation between nations in economically strong nations.. . . .
