ABSTRACT
Discussions on major changes in trade and industrial policy are going on right in both Mexico and the United States. Underdeveloped, primary commodity exporters have little need for protection, but tariffs and other indirect taxes are common to raise revenue. US history is replete with tariff conflicts. There undoubtedly would have been conflict no matter where primary responsibility for trade policy was placed, but it is undeniable that the US constitutional provision on trade regulation is tailor-made for engendering strife between the branches. Many aspects of US trade and industrial policy already are affecting Mexico. They could hardly do otherwise in light of the importance to Mexico of the US market for manufactured goods. In the trade-policy field, many of the petitions for what in the United Stages is called "fair-trade" relief have been directed against Mexican industries. There is no reason to believe that the practice of making fair-trade petitions will diminish.
