FERİT YEKTA The tariff is a tax, or duty, levied on a commodity when it crosses a national boundary. The most common tariff is the import duty, that is, the tax imposed on an imported commodity. A less common tariff is the export duty, that is, the tax levied on an exported commodity. The tariff effects on; domestic price, domestic production, the value of production and welfare, domestic consumption, the volume of trade, the international distribution of income. The tariff is the most common instrument of protection, but it is not the only one. Nations may restrict their foreign trade in many other ways. Export taxes: Export taxes are prohibited by the constitution of the United States and are extremely rare phenomena in other industrial nations. but export taxes are not uncommon in developing nations. Export duties are often levied by primary-product exporting countries either to raises revenue or to create scarcity in the world markets and thus raise world prices. For example, rice exports have been taxed by Thailand. Export subsidies: An export subsidy is a negative export tax. For this reason , a detailed analysis of export subsidies is redundant. In general, microeconomic effects of export taxes subsidies are the opposite of the corresponding effects of export taxes. The primary purpose of an export subsidy is to increase exports by switching foreign spending to domestic products. This is accomplished, of course, by effectively reducing the prices that foreigners have to pay for the subsidized exported commodities. Accordingly, the terms-of-trade effect of export subsidies is, in general, unfavourable. DUMPİNG: Dumping is international price discrimination. it occurs when a monopolist(or imperfect competitor) charges a lower price to foreign buyers than to domestic customers for the same (or a comparable) commodity. QUANTITATIVE RESTRİCTİONS Nations may also restrict their foreign trade by directly limiting the physical volume(or value) of exports their imports(import quota) or their exports(export quota).Frequently government use quantitative restrictions to protect domestic industries from foreign competition. The microeconomic effects of these quantitative restrictions are very similar to the effects of import and export taxes. EXPORT REGIME OF TURKEY Turkey has been implementing an export-oriented strategy since 1980. The basic objective of this strategy is to constitute an outward oriented economic structure in the framework of free market economy and to be integrated with world markets. With this new strategy, export intensive measures consisting of various supportive components, arrangements directed to the foreign trade liberalization. In addition to liberal arrangements made to improve exports, some support programs came into effect. The main facilities provided for the exporters were as follows: Corporation tax exemption, tax refund, premium to the Resource Utilization and Support Fund, subsidies obtained from the Support and Price Stabilization Fund. However, the above mentioned supports have been gradually eliminated in accordance with our international commitments since the second half of 1980s. On the other hand, with the establishment of the Turk Eximbank in 1987, supporting exports gained a new dimension. In this respect, in order to increase the competitive strength of the Turkish exporters in foreign markets, some credits and guarantee programs under the international commitments began to be applied to the sectors with high export potentials. Related to particularly support of exports, policies of the foreign trade strategy that was set up under the conditions of 1980s have been reviewed and modified in view of the developments taken place in the world and Turkey in the 1990s. In this respect, State Aids prepared in compliance chiefly with the World Trade Organization and our international commitments were put into practice as of 01.06.1995. The most significant phenomenon in Turkey’s foreign trade policy is the Customs Union established between the EU and Turkey as of 01.01.1996. This development initiated the duration needed for the legal infrastructural consistency of foreign trade strategy with the EU’s norms, and thus both import and export regimes have been made consistent with the regulations of the EU. THE TURKISH IMPORT REGIME OF 2004 The Import Regime of 2004, reflecting both Turkey’s international rights and obligations and the country's economic needs, has been prepared by taking into account the agreement establishing the World Trade Organization (WTO), the Customs Union Agreement between Turkey and the European Union and within this context, the free trade agreements signed with various countries ,and the preferential treatments granted by Turkey to the least developed countries and some developing countries within the context of generalized system of preferences and also the specific needs and requirements of the agricultural and industrial sectors .
