TRADE BARRIER: A restriction, invariably by government, that prevents free trade among countries. The more popular trade restrictions are tariffs, import quotas, and assorted nontariff barriers. An occasional embargo will be even thrown into this mix. The primary use of trade barriers is to restrict imports from entering in country. By restring imports, domestic producers of the restricted goods are protected from competition and are even subsidized through higher prices. Consumers, though, get the short end of this stick with higher prices and a limited choice of goods. In that producers tend to have more political clout than consumers, it's pretty obvious why trade barriers are a "natural" state of affairs.

The change in total revenue resulting from a change in the quantity of output sold. Marginal revenue indicates how much extra revenue a monopoly receives for selling an extra unit of output. It is found by dividing the change in total revenue by the change in the quantity of output. Marginal revenue is the slope of the total revenue curve and is one of two revenue concepts derived from total revenue. The other is average revenue. To maximize profit, a monopoly equates marginal revenue and marginal cost.
