Empirical aspects of protectionism: LINK results

General aspects of protectionism as they are revealed or treated in the LINK system are discussed in this paper. Attention is focused on the macroeconomic aspects of protection, about which relatively little is known: most of the vast body of knowledge on this subject concerns the microeconomic aspects of protection. Some simulations of trade liberalization (opposite of protectionism) and of protection within the context of the LINK system are reported. A movement away from protection would benefit the present world economy but not by a large enough extent to deal effectively with pressing international economic problems; therefore, trade liberalization within the context of a larger program of coordination policy among major industrial countries is examined. Finally, the relationship between protectionism and inflation is explored.
