Comparison of Different Forms of Trade Barriers
Abstract
I NTERNATIONAL comparison of trade barriers has always been complicated by the problem that the barriers take different, and not easily comparable forms: tariffs, exchange controls, differential sales taxes on domestic and imported products, explicit commodity quotas, implicit or hidden quotas (in the cases of western state trading and all of the trade conducted by the communist nations), and so forth. In 1958 a distinguished panel of experts headed by Gottfried Haberler [4] suggested that the degree of protection can be very roughly judged by the extent to which the price paid to the producer exceeds the world price for importers. . They were well aware of many of the difficulties of this method such as the effect on both domestic and world prices of the goods in question of subsidies given to both exporters and domestic producers. The United Nations Economic Commission for Europe used this technique in 1960 [ 12 ] to study agricultural protection in Western Europe. They also were aware of many of the statistical and methodological pitfalls of this technique and, in particular, called attention to the problems raised by the existence of disequilibrium exchange rates and the levy of tariffs on commodities requiring differential amounts of fabrication in the importer. Several other workers have also found the Gatt approach convenient, e.g., Dardis and Pryor [4, 8]. Pryor, interested in comparing the trade barriers by Eastern and Western Europe, respectively, to the exports of underdeveloped nations as a result of discussions which grew out of UNCTAD I. innovated by adjusting the ratios of domestic to world prices for the fact that the price levels of some nations are biased upward by a relatively large reliance on sales as opposed to income taxation. I point out in this paper two major difficulties with the use of the ratio of domestic to world (or import) price as a proper and unambiguous measure of barrier to imports. The first has to do with problems of defining barrier in view of the several different price ratio-quantity relationships which are possible under differing circumstances and assumptions. Second, the implications for this method of disequilibrium prices and repressed inflation are explored. This is particularly relevant for comparisons involving the Union of Soviet Socialist Republics and Eastern Europe [7] since the economies of these nations have consistently experienced repressed inflation. However, it is also relevant to comparisons which would have included Western Europe after World War II and some of the underdeveloped nations at present.
