Protectionism: An analysis from project LINK

The LINK system of world trade is used to examine present tendencies toward protectionism. In protectionist scenarios we increase the prices of manufactured imports into 13 LINK-OECD countries by 5, 10, and 20 percent respectively, for 1978–1979. If a country's import equations do not depend significantly on relative price, we impose corresponding quantitative import restrictions of 5, 10, and 20 percent. Smaller OECD countries, developing countries, and socialist countries are assumed to be nonprotectionist in these scenarios. The discrepancies between the values of leading variables in the protectionist scenarios and in a baseline case show the effects of the different degrees of protectionism assumed. The results describe and validate Adam Smith's principles of the gains from free trade.
