Tariff
In contrast, in economic theory tariffs are viewed as a primary element in international trade with the function of the tariff being to influence the flow of trade by lowering or raising the price of targeted goods to create what amounts to an artificial competitive advantage. When tariffs are viewed and used in this fashion, they are addressing the country's and the competitors' respective economic healths in terms of maximizing or minimizing revenue flow rather than in terms of the ability to generate and maintain a competitive advantage which is the source of the revenue. As a result, the impact of the tariffs on the economic health of the country are at best minimal but often are counter-productive.
Tariff in United States history
Tariffs up to the Smoot–Hawley Tariff Act of 1930, were set by Congress after many months of testimony and negotiations. In 1934, the U.S. Congress, in a rare delegation of authority, passed the Reciprocal Tariff Act of 1934, which authorized the executive branch to negotiate bilateral tariff reduction agreements with other countries. The prevailing view then was that trade liberalization may help stimulate economic growth. However, no one country was willing to liberalize unilaterally. Between 1934 and 1945, the executive branch negotiated over 32 bilateral trade liberalization agreements with other countries. The belief that low tariffs led to a more prosperous country are now the predominant belief with some exceptions. Multilateralism is embodied in the seven tariff reduction rounds that occurred between 1948 and 1994. In each of these "rounds", all General Agreement on Tariffs and Trade (GATT) members came together to negotiate mutually agreeable trade liberalization packages and reciprocal tariff rates. In the Uruguay round in 1994, the World Trade Organization (WTO) was established to help establish uniform tariff rates.
