LONG-RUN MARGINAL COST: The change in the long-run total cost of producing a good or service resulting from a change in the quantity of output produced. Like all marginals, long-run marginal cost is the increment in the corresponding total. What's most notable about long-run marginal cost, however, is that we are operating in the long run. Unlike the short run, in which at least one input is fixed, there are no fixed inputs in the long run. As such, there is only variable cost. This means that long-run marginal cost is the result of changes in the cost of all inputs.

IMPORTS

Goods and services produced by the foreign sector and purchased by the domestic economy. In other words, imports are goods bought from countries. Imports are the counter to exports--goods produced by the domestic economy and purchased by the foreign sector. Imports, together with exports, are the essence of foreign trade--goods and services that are traded among the citizens of different nations. Imports and exports are frequently combined into a single term, net exports (exports minus imports).
