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
When tariffs are an integral element of a country's technology strategy, some economists believe that such tariffs can be highly effective in helping to increase and maintain the country's economic health. Other economists might be less enthusiastic, as tariffs may reduce trade and there may be many spillovers and externalities involved with trade and tariffs. The existence of these externalities makes the imposition of tariffs a rather ambiguous strategy. As an integral part of the technology strategy, tariffs are effective in supporting the technology strategy's function of enabling the country to outmaneuver the competition in the acquisition and utilization of technology in order to produce products and provide services that excel at satisfying the customer needs for a competitive advantage in domestic and foreign markets. The notion that government and policy would be effective at finding new and infant technologies, rather than supporting existing politically motivated industry, rather than, say, international technology venture specialists, is however, unproven.
