Many economists discourage restrictions on trade, emphasizing the costs associated with tariffs and quotas. However, the U. S. government still receives pressure from some to erect trade barriers, and some trade barriers are still in place. Why would policymakers (such as those in Congress) understand the potential benefits from trade yet support trade restrictions? A. The benefits of trade restrictions are reaped by all industries. B. Foreign competition from free trade does not create new jobs. C. It is difficult to identify the number of jobs lost to foreign competition. D. Although trade restrictions have costs, their net benefits are always positive. E. The costs of trade restrictions per consumer are small.
